具体实施方式
下面详细描述本申请的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，旨在用于解释本申请，而不能理解为对本申请的限制。
下文的公开提供了许多不同的实施例或例子用来实现本申请的不同结构。为了简化本申请的公开，下文中对特定例子的部件和设置进行描述。当然，它们仅仅为示例，并且目的不在于限制本申请。此外，本申请可以在不同例子中重复参考数字和/或字母。这种重复是为了简化和清楚的目的，其本身不指示所讨论各种实施例和/或设置之间的关系。此外，本申请提供了的各种特定的工艺和材料的例子，但是本领域普通技术人员可以意识到其他工艺的可应用于性和/或其他材料的使用。
近些年，新能源汽车有了飞跃式的发展，在电动汽车领域，动力电池B作为电动汽车A的动力源(如图1和图2所示)，起着不可替代的重要作用。一般动力电池B由箱体和容纳于箱体内的多个电池单体组成。动力电池B作为新能源汽车核心零部件不论在安全性方面，还是循环使用寿命上均有着较高的要求。
申请人发现，传统用作动力电池B的电池中，一旦发生热失控，电池单体会释放大量排放物，排放物中的火焰温度较高，如果任其扩散，容易对电池造成二次伤害或者影响其他电池单体。基于此，申请人认为可以在电池中添加排放组件，排放组件可以收集电池单体的排放物，使得排放物不再处于自由排放状态，同时，可以在排放组件中设置防护件，以阻挡排放物中的火焰，从而避免火焰的高温对电池造成二次伤害或者影响其他电池单体。
需要说明的是，本申请实施例公开的排放组件所应用的电池可以包括传统的箱体，也可以不包括传统的箱体。此外，本申请实施例公开的电池可以但不限用于车辆、船舶或飞行器等用电装置中。例如，本申请实施例提供一种使用电池作为电源的用电装置，用电装置可以为但不限于手机、平板、笔记本电脑、电动玩具、电动工具、电瓶车、电动汽车、轮船、航天器等等。
下面，参照附图，描述根据本申请第一方面实施例的排放组件10。
如图3-图6所示，排放组件10包括排放件1，排放件1内形成有排放腔11，排放件1的壁面12上形成有进口区域13，排放腔11适于通过进口区域13接收电池单体200排出的排放物。
例如，电池单体200设于排放件1外，当发生热失控时电池单体200排出排放物，排放物如火焰、烟雾或气体等，排放物可以通过进口区域13进入排放件1，以存放于排放腔11，或者经由排放腔11导走等等。
其中，进口区域13的形式不限，例如可以是开口形式、或者是薄弱部等等，这里不作限制。因此，本文所述的“与进口区域13连通”指的是，与呈现打开状态的进口区域13连通。
如图3-图6所示，排放组件10还包括防护件2，防护件2设于排放件1内，防护件2适于在防护状态下遮挡进口区域13以至少用于阻挡排放物中的火焰，并形成连通进口区域13与排放腔11的连通通道R以使排放物中的气体可进入排放腔11。
例如，当排放物向进口区域13喷入时，处于防护状态的防护件2可以阻挡排放物中的火焰从进口区域13向排放件1内直喷，即排放物中的至少火焰部分可以被防护件2阻挡，起到较为有效的防火效果，以改善由于热失控导致的热扩散问题，而排放物中的气体可以经由连通通道R到进入排放腔11，满足热失控时的排气要求。
例如，当发生热失控时，电池单体200产生的排放物如火焰、烟雾或气体可通过进口区域13进入排放件1内，通过防护件2的阻挡，能够对排放物中的火焰有效隔离，改善热扩散问题，从而避免热扩散引起其他电池单体200受到热失控的影响，有效避免了二次伤害。
并且，由于防护件2位于排放件1内，防护件2不会占用排放件1外的空间，使得排放件1与电池单体200的配合可以更加紧凑。而且，位于排放件1内的防护件2可以获得排放件1的保护，不易脱落、磕碰损坏等，从而可以提升防护件2的防护可靠性。此外，将防护件2设于排放件1内，无需对电池单体200进行改造，从而保证了电池单体200的能量密度。
值得说明的是，防护件2的设置方式不限。例如在一些实施例中，在电池单体200没有向进口区域13排出排放物之前，防护件2可以始终处于防护状态；又例如在另外一些实施例中，在电池单体200没有向进口区域13排出排放物之前，防护件2可以处于非防护状态，而当电池单体200向进口区域13排出排放物时，或者即将向进口区域13排出排放物时，防护件2可以呈现防护状态。
需要说明的是，“防护件2遮挡进口区域13”当作广义理解，只要防护件2在形成进口区域13的壁面12上的正投影覆盖进口区域13的至少部分即可。例如在一些实施例中，防护件2在形成进口区域13的壁面12上的正投影覆盖进口区域13面积的50％以上，从而可以提升防护效果。又例如在另外一些实施例中，防护件2在形成进口区域13的壁面12上的正投影完全覆盖进口区域13，如覆盖范围恰好与进口区域13相同，或者覆盖范围超出进口区域13，都可以更加有效地提升防护效果。
需要说明的是，连通通道R的形成方式不限，例如在一些实施例中，连通通道R可以是由排放件1与防护件2共同限定出而形成的；又例如在一些实施例中，连通通道R还可以是由防护件2独自限定形成的等等，这里不作限定。
例如在一些具体示例中，如图28所示，当连通通道R由排放件1与防护件2共同限定出时，防护件2在防护状态下，防护件2与形成进口区域13的壁面12内外间隔开设置，以在防护件2与该壁面12之间形成连通通道R，连通通道R从防护件2的边缘处与排放腔11连通，防护件2与进口区域13相对，以使连通通道R与进口区域13连通。由此，结构简单、便于加工。值得说明的是，本文所述的“与壁面12内外间隔开设置”指的是，沿壁面12的厚度方向、与壁面12间隔开设置。
或者，如图28所示，当连通通道R由排放件1与防护件2共同限定出时，防护件2在防护状态下，防护件2与形成进口区域13的壁面12内外间隔开设置，以在防护件2与该壁面12之间形成连通通道R，防护件2上具有与进口区域13错开设置的贯通孔23，即贯通孔23在形成进口区域13的壁面12上的正 投影与进口区域13错开，连通通道R通过贯通孔23与排放腔11连通，从而从进口区域13直喷的排放物中的火焰可以被防护件2阻挡，而排放物中的气流可以通过贯通孔23进入排放腔11，由此也可以满足排气和防火双重要求。
再或者，如图28所示，当连通通道R由排放件1与防护件2共同限定出时，防护件2在防护状态下，防护件2与形成进口区域13的壁面12内外间隔开设置，以在防护件2与该壁面12之间形成连通通道R，连通通道R从防护件2的边缘处与排放腔11连通，同时，防护件2上具有与进口区域13错开设置的贯通孔23，连通通道R还通过贯通孔23与排放腔11连通。由此，可以提升排气效率，提高安全性。
又例如在一些具体示例中，如图29所示，当连通通道R由防护件2独自限定出时，防护件2可以为中空壳体以在防护件2内形成连通通道R，防护件2的周侧壁具有开口24以使连通通道R与排放腔11连通，防护件2与形成进口区域13的壁面12非间隔地贴合设置且使连通通道R与进口区域13连通，防护件2的内侧壁与形成进口区域13的壁面12内外间隔开地设置且遮挡进口区域13以起到防火作用。由此，可以提高排放组件10整体的结构强度。
值得说明的是，排放件1可以仅单侧设有进口区域13，排放件1也可以在相对两侧分别设置进口区域13，在一些实施例中，当两侧的进口区域13均都能被防护件2(可以是同一个防护件2，或者不同的防护件2)遮挡时，防护件2可以起到防止两侧对喷的效果，即避免单侧的排放物直喷到对侧，以避免出现热失控对喷导致的危险，从而提高安全性。
需要说明的是，根据本申请实施例的防护件2的具体构成和材料不限。例如在一些实施例中，防护件2可以为防火件，以具有较好的耐热和隔热作用，从而起到较为有效的防热扩散效果。其中，防火件的形式不限，例如结合图30，防火件可以是防火材料板2a，如云母板等；又例如结合图31，防火件可以包括基体2b和设于基体2b外的防火层2c，防火层2c可以是粘接或喷涂于基体2b，例如防火层2c可以是气凝胶层、聚丙烯等材料层、或防火漆层等，基体2b可以是板体、或梁体等等。
值得说明的是，本申请的防护件2不限于是防火件，例如在本申请的其他实施例中，防护件2还可以具有除防火以外的其他功能，例如还可以具有烟雾吸附功能、绝缘功能、防水功能等等，这里不作赘述。
此外，在本申请的一些其他实施例中，排放组件10除了包括防护件2之外，例如还可以包括其他功能件，例如结构支撑件、冷却件、颗粒物收集件等等。
在本申请的一些实施例中，排放组件10用于电池1000，电池1000包括至少一个电池单体200。由此，通过设置根据本申请实施例的排放组件10，在发生热失控时既能满足排气需求，又能改善热扩散问题，从而避免电池1000的热扩散失效问题。例如，电池单体200可以设于排放件1的形成有进口区域13的位置外侧，电池单体200的泄压区域2002(如泄压结构或薄弱部)面对进口区域13设置，以便于热失控时朝向进口区域13快速排放。或者，当电池单体200未设置泄压区域，如传统的软包电池单体，可以在每一个软包电池单体处对应设置一个进口区域13，排放物能够经由较短的路径即进入排放件1内。
根据本申请一些实施例的电池1000，可以包括用于封装一个或多个电池单体200的箱体，箱体可以避免液体或其他异物影响电池单体200的充电或放电。或者，根据本申请另一些实施例的电池1000，电池1000也可以不包括用于封装一个或多个电池单体200的箱体，例如，直接将排放组件10和电池单体200设于用电装置2000的安装腔内等等。
当电池单体200为多个时，可以是将多个电池单体200无模组化地直接设置于箱体或用电装置2000的安装腔内，此时，多个电池单体200之间可串联和/或并联，或者，也可以将多个电池单体200组成电池模组，将多个电池模组放置于箱体或用电装置2000的安装腔内，此时，各电池模组中的多个电池单体200之间可串联和/或并联，多个电池模组之间也可串联和/或并联。
需要说明的是，根据本申请实施例的电池单体200的形状及类型不限，按照形状可以为圆柱体、扁平片体、或长方体或其它形状等，按照封装类型可以为柱形电池单体、方形电池单体、或软包电池单体等。此外，电池单体200可以包括锂离子二次电池单体、锂离子一次电池单体、锂硫电池单体、钠锂离子电池单体、钠离子电池单体或镁离子电池单体等，对此不作限定。
例如，电池单体200可以包括电极组件和电解液。电极组件包括正极极片、负极极片和隔离膜，电极组件可以是卷绕式结构或叠片式结构等。其中，正极极片包括正极集流体和正极活性物质层，负极极 片包括负极集流体和负极活性物质层。以锂离子电池为例，正极集流体的材料可以为铝，正极活性物质可以为钴酸锂、磷酸铁锂、三元锂或锰酸锂等，负极集流体的材料可以为铜，负极活性物质可以为碳或硅等，这里不作赘述。
当发生热失控时，电池单体200产生的排放物如火焰、烟雾或气体可通过进口区域13进入排放件1内，通过防护件2的阻挡，能够对排放物中的至少火焰进行一定程度的隔离，改善热扩散问题，从而避免热扩散引起电池1000内的其他电池单体200受到热失控的影响，有效避免了热扩散对电池1000造成的二次伤害。
在本申请的一些实施例中，如图6和图7所示，排放件1包括第一壁面121，进口区域13包括形成在第一壁面121上的多个第一进口区域131，防护件2包括第一防护件21，第一防护件21在防护状态下与第一壁面121内外间隔开且在第一壁面121上的正投影覆盖第一进口区域131。由此，通过第一防护件21与第一壁面121的间隔设置可以形成连通通道R，通过第一防护件21在第一壁面121上的正投影覆盖第一进口区域131，可以起到遮挡第一进口区域131以阻挡从第一进口区域131直喷进入的火焰。因此，第一防护件21的设置方案简单，容易实现，且可以具有较好的防护效果。
值得说明的是，本文所述的“与第一壁面121内外间隔开设置”指的是，沿第一壁面121的厚度方向、与第一壁面121间隔开设置。
在本申请的一些实施例中，如图8所示，第一防护件21为多个且间隔开设置，每个第一进口区域131分别由一个对应的第一防护件21防护。也就是说，第一防护件21的数量与第一进口区域131的数量相同且一一对应设置，以实现一对一地单独防护。由此，可以减小第一防护件21的面积和成本，而且，相邻两个第一防护件21之间的间隔位置可以形成连通排放腔11与连通通道R的流体路径，有利于连通通道R快速向排放腔11排气，提升排气效率，提高安全性。
在本申请的另外一些实施例中，如图9所示，至少两个相邻第一进口区域131由同一个第一防护件21防护。也就是说，第一防护件21的数量少于第一进口区域131的数量，以实现一对多地防护。由此，可以减少第一防护件21的数量，提高第一防护件21的安装效率。
例如在一些示例中，如图10所示，全部第一进口区域131由同一个第一防护件21防护，也就是说，第一防护件21在防护状态下在第一壁面121上的正投影覆盖全部第一进口区域131。由此，第一防护件21更加便于安装，提高排放组件10的整体生产效率。
例如在一些示例中，如图10所示，多个第一进口区域131沿排放件1的长度方向X排列以形成第一入口排141，第一入口排141中的各第一进口区域131由同一个第一防护件21防护，例如，第一防护件21可以沿排放件1的长度方向X延伸，且第一防护件21在防护状态下在第一壁面121上的正投影覆盖第一入口排141中全部第一进口区域131。由此，第一防护件21的结构简单、便于安装，可以提高排放组件10的生产效率。
需要说明的是，排放件1的长度方向即为排放组件10的长度方向，均为图中标识的X方向。排放件1的宽度方向即为排放组件10的宽度方向，均为图中标识的Y方向。排放件1的高度方向即为排放组件10的高度方向，均为图中标识的Z方向。
进一步地，如图11所示，第一壁面121上形成有沿排放件1的高度方向Z排列的多个第一入口排141，对应各第一入口排141设置的第一防护件21沿排放件1的高度方向Z间隔开设置，例如，第一防护件21的数量与第一入口排141的数量相同，多个第一防护件21沿排放件1的高度方向Z间隔设置，以实现第一防护件21与第一入口排141的一对一设置。由此，在满足第一防护件21的结构简单、便于安装的前提下，由于沿高度方向Z间隔开设置的相邻两个第一防护件21之间的间隔位置可以形成连通排放腔11与连通通道R的流体路径，有利于连通通道R快速向排放腔11排气，提升排气效率，提高安全性。
例如在一些示例中，如图12所示，多个第一进口区域131沿排放件1的高度方向Z排列以形成第一入口列151，第一入口列151中的各第一进口区域131由同一个第一防护件21防护。例如，第一防护件21可以沿排放件1的高度方向Z延伸，且第一防护件21在防护状态下在第一壁面121上的正投影覆盖第一入口列151中全部第一进口区域131。由此，第一防护件21的结构简单、便于安装，可以提高排放组件10的生产效率。
进一步地，如图12所示，第一壁面121上形成有沿排放件1的长度方向X排列的多个第一入口列151，对应各第一入口列151设置的第一防护件21沿排放件1的长度方向X间隔开设置。例如，第一防护件21的数量与第一入口列151的数量相同，多个第一防护件21沿排放件1的长度方向X间隔设置，以实现第一防护件21与第一入口列151的一对一设置。由此，在满足第一防护件21的结构简单、便于安装的前提下，由于沿长度方向X间隔开设置的相邻两个第一防护件21之间的间隔位置可以形成连通排放腔11与连通通道R的流体路径，有利于连通通道R快速向排放腔11排气，提升排气效率，提高安全性。
在本申请的一些实施例中，如图3-图6所示，排放件1为长条形结构，也就是说，排放件1的长度大于宽度和高度，且排放件1的长度、宽度、高度三者两两相互垂直。第一进口区域131设于排放件1的宽度方向Y至少一侧，由此，通过将第一进口区域131设置于宽度方向Y至少一侧，从而可以利用排放件1的较大的壁面设置第一进口区域131，增多第一进口区域131的数量，有利于排放件1与更多数量的电池单体200配合。
在本申请的一些实施例中，如图13所示，第一防护件21上可以具有第一贯通孔211，第一贯通孔211在第一壁面121上的正投影与第一进口区域131错开。由此，可以利用第一贯通孔211形成连通排放腔11与连通通道R的流体路径的至少部分，有利于连通通道R快速向排放腔11排气，提升排气效率，提高安全性。例如，从第一进口区域131直喷进入的排放物中的火焰可以被第一防护件21有效阻挡，而从第一进口区域131直喷进入的排放物中的气体可以经由第一贯通孔211排出到排放腔11，从而可以在保证防火效果的同时满足排气要求，提高安全性。
需要说明的是，无论第一防护件21用于遮挡几个第一进口区域131，第一防护件21上均可以根据需求设置第一贯通孔211，即第一贯通孔211的设置方案不限于图13所示实施例。
在一些具体示例中，如图14所示，通过第一防护件21的边缘形成连通排放腔11与连通通道R的流体路径的一部分，通过第一贯通孔211形成连通排放腔11与连通通道R的流体路径的一部分，从而可以更加有利于连通通道R向排放腔11的快速排气，有利于提升排气效率。
在本申请的一些实施例中，如图14所示，排放件1包括第二壁面122，进口区域13包括形成在第二壁面122上的多个第二进口区域132，第一防护件21在防护状态下与第二壁面122内外间隔开且在第二壁面122上的正投影覆盖第二进口区域132。由此，通过第一防护件21与第二壁面122的间隔设置可以形成连通通道R，通过第一防护件21在第二壁面122上的正投影覆盖第二进口区域132，可以起到遮挡第二进口区域132以阻挡从第二进口区域132直喷进入的火焰。因此，第一防护件21具有双重防护功能，即可以防护第一进口区域131又可以防护第二进口区域132，从而可以简化防护件2的设置和安装。
值得说明的是，本文所述的“与第二壁面122内外间隔开设置”指的是，沿第二壁面122的厚度方向、与第二壁面122间隔开设置。
需要说明的是，第一壁面121与第二壁面122的相对位置不限，例如可以是相邻的壁面，又例如还可以是相对的壁面。例如，当第一壁面121与第二壁面122是相邻的壁面时，结合图15所示，第一防护件21可以为折角形式。又例如，结合图14所示，当第一壁面121与第二壁面122是相对的壁面时，例如排放件1的宽度方向两侧壁面时，第一防护件21为板形、梁形等等。
例如在一些实施例中，如图14所示，第二壁面122与第一壁面121为排放件1的相对两侧壁，第一防护件21位于第一壁面121与第二壁面122之间，第二壁面122位于第一防护件21背离第一壁面121的一侧。由此，第一防护件21的形状不限，可以实现灵活设置。另外，通过在相对两侧之间设置第一防护件21进行防护，可以起到防两侧对喷的效果，进一步提高安全性。
其中，如图16所示，第一进口区域131与第二进口区域132可以是正对的，从而使得第一壁面121外侧的电池单体200与第二壁面122外侧的电池单体200可以是正对设置的，从而有利于提高空间利用率，提高能量密度。或者，如图17所示，第一进口区域131与第二进口区域132也可以是错开的，即非正对设置，从而可以进一步起到防两侧对喷的效果，提高安全性。
在本申请的一些实施例中，排放件1为长条形结构，也就是说，排放件1的长度大于宽度和高度，且排放件1的长度、宽度、高度三者两两相互垂直。第二壁面122与第一壁面121为排放件1的宽度两侧壁，从而第一进口区域131可以设于排放件1的宽度一侧，第二进口区域132设于排放件1的宽度另 一侧，从而可以利用排放件1的较大壁面设置第一进口区域131和第二进口区域132，增多第一进口区域131和第二进口区域132的数量，有利于排放件1与更多数量的电池单体200配合，提高能量密度。结合图14，第一防护件21位于第一壁面121与第二壁面122之间的中央位置，例如第一防护件21沿排放件1的长度方向延伸且位于排放件1宽度方向的中央位置。由此，可以简化结构设计，且具有较好的防护效果以及较大的排气空间。
在本申请的一些实施例中，如图14所示，第一防护件21上具有第一贯通孔211，第一贯通孔211在第一壁面121上的正投影与第一进口区域131错开，且第一贯通孔211在第二壁面122上的正投影与第二进口区域132错开。由此，可以利用第一贯通孔211形成连通第一防护件21的两侧，增大排气容积，避免排气容积不足导致的憋爆问题，提高安全性。例如，从第一进口区域131直喷进入的排放物中的火焰可以被第一防护件21有效阻挡，而从第一进口区域131直喷进入的排放物中的气体可以经由第一贯通孔211排出到排放腔11，同时，从第二进口区域132直喷进入的排放物中的火焰可以被第一防护件21有效阻挡，而从第二进口区域132直喷进入的排放物中的气体可以经由第一贯通孔211排出到排放腔11，从而可以在保证防火效果的同时满足排气要求，提高安全性。
在一些具体示例中，如图14所示，通过第一防护件21的边缘形成连通排放腔11与连通通道R的流体路径的一部分，通过第一贯通孔211形成连通排放腔11与连通通道R的流体路径的一部分，从而可以更加有利于连通通道R向排放腔11的快速排气，有利于提升排气效率。而且可以连通第一防护件21的两侧，增大排气容积，避免排气容积不足导致的憋爆问题，提高安全性。
综上，通过设置第一防护件21，可以有效地解决对喷问题，起到较为有效的防对喷效果，同时又平衡了排气空间和能量密度两个维度的设计。
在本申请的一些实施例中，如图18和图19所示，排放件1包括第二壁面122，进口区域13包括形成在第二壁面122上的多个第二进口区域132，防护件2包括第二防护件22，第二防护件22在防护状态下与第二壁面122内外间隔开且在第二壁面122上的正投影覆盖第二进口区域132。由此，通过第二防护件22与第二壁面122的间隔设置可以形成连通通道R，通过第二防护件22在第二壁面122上的正投影覆盖第二进口区域132，可以起到遮挡第二进口区域132以阻挡从第二进口区域132直喷进入的火焰。因此，第二防护件22的设置方案简单，容易实现，且可以具有较好的防护效果。
值得说明的是，本文所述的“与第二壁面122内外间隔开设置”指的是，沿第二壁面122的厚度方向、与第二壁面122间隔开设置。
由此，第一防护件21和第二防护件22分别对应不同壁面12上的进口区域13防护，从而可以实现第一防护件21和第二防护件22的灵活设计，具有多种实施方式。需要说明的是，第一壁面121与第二壁面122的相对位置不限，例如可以是相邻的壁面，又例如还可以是相对的壁面。
例如在一些实施例中，如图18和图19所示，第二壁面122与第一壁面121为排放件1的相对两侧壁，第二防护件22设于第一防护件21的靠近第二壁面122的一侧。即第一防护件21和第二防护件22均位于第一壁面121与第二壁面122之间，第一防护件21相对第二防护件22靠近第一壁面121设置，第二防护件22相对第一防护件21靠近第二壁面122设置。由此，结构简单、便于加工、防护效果较好。
另外，通过在相对两侧之间设置第一防护件21和第二防护件22进行防护，可以起到防两侧对喷的效果，进一步提高安全性。其中，结合图16，第一进口区域131与第二进口区域132可以是正对的，从而使得第一壁面121外侧的电池单体200与第二壁面122外侧的电池单体200可以是正对设置的，从而有利于提高空间利用率，提高能量密度。或者，结合图17，第一进口区域131与第二进口区域132也可以是错开的，即非正对设置，从而可以进一步起到防两侧对喷的效果，提高安全性。
在本申请的一些实施例中，排放件1为长条形结构，也就是说，排放件1的长度大于宽度和高度，且排放件1的长度、宽度、高度三者两两相互垂直。第二壁面122与第一壁面121为排放件1的宽度两侧壁，从而第一进口区域131可以设于排放件1的宽度一侧，第二进口区域132设于排放件1的宽度另一侧，从而可以利用排放件1的较大壁面设置第一进口区域131和第二进口区域132，增多第一进口区域131和第二进口区域132的数量，有利于排放件1与更多数量的电池单体200配合，提高能量密度。第一防护件21和第二防护件22均沿排放件1的长度方向X延伸且均位于第一壁面121与第二壁面122之间，第一防护件21相对第二防护件22靠近第一壁面121设置，第二防护件22相对第一防护件21靠 近第二壁面122设置。由此，可以简化结构设计，且具有较好的防护效果以及较大的排气空间。
在一些实施例中，如图18和图19所示，第二防护件22与第一防护件21间隔开设置，从而可以在第一防护件21与第二防护件22之间形成排放腔11的至少部分，这样既可以兼顾较大的排气空间，又可以起到较为可靠的防护效果。
在本申请的一些实施例中，如图20所示，第二防护件22为多个且间隔开设置，每个第二进口区域132分别由一个对应的第二防护件22防护。也就是说，第二防护件22的数量与第二进口区域132的数量相同且一一对应设置，以实现一对一地单独防护。由此，可以减小第二防护件22的面积和成本，而且，相邻两个第二防护件22之间的间隔位置可以形成连通排放腔11与连通通道R的流体路径，有利于连通通道R快速向排放腔11排气，提升排气效率，提高安全性。
在本申请的另外一些实施例中，如图21所示，至少两个相邻第二进口区域132由同一个第二防护件22防护。也就是说，第二防护件22的数量少于第二进口区域132的数量，以实现一对多地防护。由此，可以减少第二防护件22的数量，提高第二防护件22的安装效率。
例如在一些示例中，如图22和图23所示，全部第二进口区域132由同一个第二防护件22防护，也就是说，第二防护件22在防护状态下在第二壁面122上的正投影覆盖全部第二进口区域132。由此，第二防护件22更加便于安装，提高排放组件10的整体生产效率。
例如在一些示例中，如图24所示，多个第二进口区域132沿排放件1的长度方向X排列以形成第二入口排142，第二入口排142中的各第二进口区域132由同一个第二防护件22防护，例如，第二防护件22可以沿排放件1的长度方向X延伸，且第二防护件22在防护状态下在第二壁面122上的正投影覆盖第二入口排142中全部第二进口区域132。由此，第二防护件22的结构简单、便于安装，可以提高排放组件10的生产效率。
进一步地，如图24所示，第二壁面122上形成有沿排放件1的高度方向Z排列的多个第二入口排142，对应各第二入口排142设置的第二防护件22沿排放件1的高度方向Z间隔开设置，例如，第二防护件22的数量与第二入口排142的数量相同，多个第二防护件22沿排放件1的高度方向Z间隔设置，以实现第二防护件22与第二入口排142的一对一设置。由此，在满足第二防护件22的结构简单、便于安装的前提下，由于沿高度方向Z间隔开设置的相邻两个第二防护件22之间的间隔位置可以形成连通排放腔11与连通通道R的流体路径，有利于连通通道R快速向排放腔11排气，提升排气效率，提高安全性。
例如在一些示例中，如图25所示，多个第二进口区域132沿排放件1的高度方向Z排列以形成第二入口列152，第二入口列152中的各第二进口区域132由同一个第二防护件22防护。例如，第二防护件22可以沿排放件1的高度方向Z延伸，且第二防护件22在防护状态下在第二壁面122上的正投影覆盖第二入口列152中全部第二进口区域132。由此，第二防护件22的结构简单、便于安装，可以提高排放组件10的生产效率。
进一步地，如图25所示，第二壁面122上形成有沿排放件1的长度方向X排列的多个第二入口列152，对应各第二入口列152设置的第二防护件22沿排放件1的长度方向X间隔开设置。例如，第二防护件22的数量与第二入口列152的数量相同，多个第二防护件22沿排放件1的长度方向X间隔设置，以实现第二防护件22与第二入口列152的一对一设置。由此，在满足第二防护件22的结构简单、便于安装的前提下，由于沿长度方向X间隔开设置的相邻两个第二防护件22之间的间隔位置可以形成连通排放腔11与连通通道R的流体路径，有利于连通通道R快速向排放腔11排气，提升排气效率，提高安全性。
在本申请的一些实施例中，如图23所示，第二防护件22上具有第二贯通孔221，第二贯通孔221在第二壁面122上的正投影与第二进口区域132错开。由此，可以利用第二贯通孔221形成连通排放腔11与连通通道R的流体路径的至少部分，有利于连通通道R快速向排放腔11排气，提升排气效率，提高安全性。例如，从第二进口区域132直喷进入的排放物中的火焰可以被第二防护件22有效阻挡，而从第二进口区域132直喷进入的排放物中的气体可以经由第二贯通孔221排出到排放腔11，从而可以在保证防火效果的同时满足排气要求，提高安全性。而且通过设置第二贯通孔221，可以增大排气容积，避免排气容积不足导致的憋爆问题，提高安全性。
需要说明的是，无论第二防护件22用于遮挡几个第二进口区域132，第二防护件22上均可以根据需求设置第二贯通孔221，即第二贯通孔221的设置方案不限于图23所示实施例。
当第二防护件22上具有第二贯通孔221，第二贯通孔221在第二壁面122上的正投影与第二进口区域132错开时，在一些示例中，第一防护件21上同时可以具有第一贯通孔211，第一贯通孔211在第一壁面121上的正投影与第一进口区域131错开。由此，从第一进口区域131直喷进入的排放物中的火焰可以被第一防护件21有效阻挡，而从第一进口区域131直喷进入的排放物中的气体可以经由第一贯通孔211排出到排放腔11，同时，从第二进口区域132直喷进入的排放物中的火焰可以被第二防护件22有效阻挡，而从第二进口区域132直喷进入的排放物中的气体可以经由第二贯通孔221排出到排放腔11，从而可以在保证防火效果的同时满足排气要求，提高安全性，而且可以增大排气容积，避免排气容积不足导致的憋爆问题，提高安全性。其中，第一贯通孔211与第二贯通孔221可以是正对的，也可以是错开的，可以根据需要具体设计，这里不作限制。
在一些实施例中，如图5和图6所示，第二壁面122与第一壁面121为排放件1的宽度两侧壁，排放件1内设有沿排放件1的长度方向X延伸的支撑梁16，第一防护件21设于支撑梁16的朝向第一壁面121的一侧，第二防护件22设于支撑梁16的朝向第二壁面122的一侧，支撑梁16上具有第三贯通孔161。
由此，通过设置支撑梁16，可以使得排放件1的结构强度较好，并且通过在支撑梁16上设置第三贯通孔161，从第一进口区域131进入的气体可以经由第一贯通孔211和第三贯通孔161来到支撑梁16的朝向第二防护件22的一侧，从第二进口区域132进入的气体可以经由第二贯通孔221和第三贯通孔161来到支撑梁16的朝向第一防护件21的一侧，从而使得排放件1内的排气空间较大，避免排气容积不足导致的憋爆问题，提高安全性。
其中，第三贯通孔161与第二贯通孔221可以是正对的，也可以是错开的，可以根据需要具体设计，这里不作限制。同理，第三贯通孔161与第一贯通孔211可以是正对的，也可以是错开的，可以根据需要具体设计，这里不作限制。
例如在上述实施例中，排放腔11的一部分可以位于第一防护件21与支撑梁16之间，排放腔11的另一部分可以位于第二防护件22与支撑梁16之间。或者还可以是，排放腔11的一部分可以位于第一防护件21与支撑梁16之间，排放腔11的一部分可以位于第二防护件22与支撑梁16之间，排放腔11的其余部分可以位于支撑梁16内，等等。这里不作赘述。
综上，通过设置第一防护件21和第二防护件22，可以有效地解决对喷问题，起到较为有效的防对喷效果，同时又平衡了排气空间和能量密度两个维度的设计。
在本申请的一些实施例中，至少一个防护件2的设置位置固定。当防护件2相对排放件1是不可调节位置时，可以降低防护件2的设置难度，容易加工，且防护件2常呈现防护状态，防护效果较为可靠。
例如结合图26，排放件1内设有支撑梁16，防护件2固定地设于支撑梁16上。由此，在提高排放件1结构强度的前提下，可以降低防护件2的设置难度，保证防护件2的设置位置固定，使得防护件2可以起到较为有效的防护效果。需要说明的是，防护件2与支撑梁16的连接方式不限，例如可以是直接或间接装配形式连接(如粘贴、卡扣连接、螺纹连接、焊接等等)，又例如还可以是涂层形式连接，等等。
当防护件2固定地设于支撑梁16上时，在一些实施例中，防护件2与支撑梁16相应位置的壁面形状相匹配，从而可以提高连接可靠性，提高支撑梁16对防护件2的支撑效果，并且使得配合位置更加紧凑，节省空间，提高排气空间。当然，本申请不限于此，例如在本申请的其他实施例中，也可以将防护件2与支撑梁16设置为形状不是匹配的，以满足不同设计要求。
例如，当防护件2为板形时，可以包括平行于形成有进口区域13的壁面12的平板、倾斜于形成有进口区域13的壁面12的斜面板、以及曲面板等等，这里不作限定。
当然，本申请不限于此，防护件2也可以并非设置位置固定，例如在一些实施例中，至少一个防护件2的位置或形状可变化设置，从而可以满足其他设计要求。
例如结合图5，至少一个防护件2沿相应进口区域13的进入方向可变形或可移动。这样，在防护件2阻止火焰时，可以通过防护件2的位置或形状变化，增大连通通道R，从而可以提升排气效率，提高安全性。
具体而言，实现上述移动的方式可以有多种，例如可以是通过驱动而实现移动，或者也可以是自动 移动。例如在一些具体示例中，结合图5和图6，排放组件10包括支撑件4，支撑件4用于支撑位置可变化的防护件2，支撑件4构造为在排放物的温度作用下可融化，以使相应的防护件2的位置可变化。例如，可以在支撑梁16与防护件2之间设置支撑件4，当防护件2阻挡排放物中的火焰时，支撑件4可以发生融化，以使防护件2的位置可移动，从而可以增大排气空间，提高排气效率。需要说明的是，支撑件4的选材不限，例如可以是泡棉等。
又例如，结合图27，至少一个防护件2沿同一壁面12上多个进口区域13的间隔开方向可移动，以可选择地防护不同进口区域13。这样，在发生热失控时，可以将防护件2的位置调节到有排放物进入的进口区域13，以阻挡火焰，从而可以减少防护件2的设置数量，降低防护件2的成本。
具体而言，实现上述移动的方式可以有多种，例如可以是通过驱动而实现移动，或者也可以是自动移动。例如在一些具体示例中，结合图27，排放组件10包括驱动装置3，驱动装置3用于驱动可移动的防护件2。可选地，驱动装置3可以与监测***相连，监测***可监测到哪一电池单体200要排出排放物，从而驱动装置3可以根据监测结果驱动防护件2运动到对应的位置，这里不作赘述。其中，驱动装置3的具体构成不限，可以灵活选择，只要能够实现驱动防护件2移动即可。
在本申请的一些实施例中，结合图32，排放组件10还可以包括：阻隔件5，阻隔件5设于排放腔11内，且阻隔在同侧相邻两个进口区域13之间。由此，可以避免相邻两个进口区域13之间的蹿火问题。需要说明的是，本文所述的阻隔件5至少具有防火功能。
需要说明的是，根据本申请实施例的排放件1的功能不限于此。例如在本申请的一些实施例中，排放件1还可以包括换热部，换热部用于与电池单体200和排放腔11中的至少一个交换热量，以为电池单体200和排放腔11中的至少一个散热，从而实现冷却的效果，降低热蔓延的概率。由此，排放件1在保证排气功能的前提下，还兼具散热功能。
例如，换热部可以包括换热腔，换热腔内可以填充可流动的换热流体，换热流体可以在换热腔中流动，依靠流动性不断地与排放腔11内的排放物进行热量交换，将排放腔11中聚集的热量带走，降低出现热量集中的概率，提高安全性，降低发生热蔓延的概率。
例如图3-图6所示，排放件1可以包括支撑梁16和设于支撑梁16外的冷板17，支撑梁16上设有防护件2，或支撑梁16与冷板17之间设有防护件2，支撑梁16内限定出排放腔11，或者支撑梁16与防护件2之间限定出排放腔11，冷板17上形成有与排放腔11连通的进口区域13，冷板17内形成有换热腔。例如，支撑梁16的宽度方向Y两侧分别设有冷板17，每个冷板17的背离支撑梁16的一侧分别设有电池单体200，如电池单体200成单排或多排放置于冷板17的外侧，排放腔11位于冷板17的内侧。
由此，排放件1为分层设置，便于加工制造，而且能够增大换热腔与电池单体200热交换的面积，同时，还能够增大换热腔与排放腔11的导热面积，有利于提高散热冷却效果。冷板17还可以将排放腔11与电池单体200分隔，避免高温的排放物对电池单体200造成不良的热影响。另外，排放件1宽度方向Y两侧的电池单体200共用同一个排放件1，可以提高结构紧凑性。
下面，参照附图，描述根据本申请第二方面实施例的箱体100。
如图33-图36所示，根据本申请实施例的箱体100，限定出用于容置电池单体200的容置腔1001，即可以将电池单体200设置于容置腔1001内，箱体100包括根据本申请第一方面实施例的排放组件10。由此，根据本申请实施例的箱体100，由于设置有排放组件10，热失控时，电池单体200产生的排放物如火焰、烟雾或气体可通过进口区域13进入排放件1内，通过防护件2的阻挡，能够对排放物中的火焰有效隔离，改善热扩散问题，从而避免热扩散引起其他电池单体200受到热失控的影响，有效避免了二次伤害。
而且，将排放组件10集成于箱体100，排放组件10在实现排气功能的同时，还能够作为箱体100的一部分加强结构，例如作为箱体100的梁，使得箱体100可以减少、甚至去除一些梁结构，使得采用该箱体100的电池1000的空间利用率更高，结构更紧凑，能量密度更高。需要说明的是，排放组件10在箱体100的设置位置不限，例如，下面介绍一些实施例。
例如，如图33-图36所示，箱体100包括边框20和分隔梁30，分隔梁30位于边框20围绕出的空间内，以将空间划分为多个容置腔1001，边框20和分隔梁30中的至少一个构造为排放组件10，此时电池单体200可以位于排放组件10的水平一侧，热失控时电池单体200可以沿水平方向排放。
此外，当在分隔梁30的两侧分别设置电池单体200，且将分隔梁30构造为排放组件10时，两侧电池单体200可以共用排放组件10，从而可以减少排放组件10的数量，降低成本，提高排放效率，而且可以提高结构紧凑性，进而提高能量密度。
例如，如图35所示，分隔梁30包括沿箱体100的长度方向F1延伸的纵梁40(而不包括沿箱体100的宽度方向F2方向延伸的横梁50)，纵梁40构造为排放组件10。
例如，如图36所示，分隔梁30包括沿箱体100的宽度方向F2方向延伸的横梁50(而不包括沿箱体100的长度方向F1延伸的纵梁40)，横梁50构造为排放组件10。
例如，如图34所示，分隔梁30包括沿箱体100的长度方向F1延伸的纵梁40和沿箱体100的宽度方向F2方向延伸的横梁50，纵梁40和横梁50中的至少一个构造为排放组件10。
例如，如图33所示，箱体100包括顶盖60(而不包括底板70)，顶盖60包括排放组件10，此时电池单体200可以位于排放组件10的下方，热失控时电池单体200可以向上排放。
例如，如图33和图34所示，箱体100包括底板70(而不包括顶盖60)，底板70包括排放组件10，此时电池单体200可以位于排放组件10的上方，热失控时电池单体200可以向下排放。
例如，如图33和图34所示，箱体100包括顶盖60和底板70，顶盖60和底板70中的至少一个包括排放组件10。
例如，箱体100同时包括边框20、分隔梁30、顶盖60和底板70，其中，边框20、分隔梁30、顶盖60和底板70中的至少两个包括排放组件10。
由此可以看出，排放组件10的设计灵活，可以满足不同箱体100的设计要求，应用范围广泛。
此外，在本申请的实施例中，当分隔梁30构造为排放组件10且包括排放路径时，边框20、顶盖60和底板70中的至少一个上可以具有排出路径，排放路径与排出路径连通，从而可以将排放物排出。例如图38所示，分隔梁30构造为排放组件10时，进入排放组件10内的排放物可以向下朝向底板70排放。例如图39-图41所示，分隔梁30构造为排放组件10时，进入排放组件10内的排放物可以沿长度方向朝向边框20排放。
下面，参照附图，描述根据本申请第三方面实施例的电池1000。
如图33和图34所示，根据本申请实施例的电池1000，包括：箱体100和电池单体200，箱体100为根据本申请第二方面实施例的箱体100，电池单体200为多个且设于容置腔1001。由此，根据本申请实施例的电池1000，由于箱体100设置有排放组件10，热失控时，电池单体200产生的排放物如火焰、烟雾或气体可通过进口区域13进入排放件1内，通过防护件2的阻挡，能够对排放物中的火焰有效隔离，改善热扩散问题，从而避免热扩散引起其他电池单体200受到热失控的影响，有效避免了二次伤害。
在本申请的一些实施例中，箱体100包括用于将箱体100内的空间划分为多个容置腔1001分隔梁30，分隔梁30构造为排放组件10，因此排放组件10可以为长条形的梁体结构，分隔梁30的长度方向即为排放组件10的长度方向X，分隔梁30的宽度方向即为排放组件10的宽度方向Y，分隔梁30的高度方向即为排放组件10的高度方向Z，高度方向Z、宽度方向Y与长度方向X三者两两相互垂直，例如当电池1000应用于车辆时，长度方向X和宽度方向Y均可以水平设置，高度方向Z可以竖直设置。
在一些实施例中，如图33所示，排放组件10的宽度方向Y上的至少一侧设有电池排300，电池排300包括沿排放组件10的长度方向X依次排列的多个电池单体200，每个电池单体200分别单独向排气路径排放。由此，设置方案简单，排放组件10可以用于多个电池单体200热失控时的排放，电池1000的结构紧凑性更好，能量密度更高。需要说明的是，电池排300中的多个电池单体200可以是并联和/或串联，这里不作限制。
在一些具体示例中，如图33所示，排放组件10的宽度方向Y上的两侧分别设有电池排300。由此，两侧的电池排300可以共用同一个排放组件10排放，使得结构紧凑，可以提高空间利用率，提高电池1000的能量密度。
例如可选地，如图33所示，当排放组件10的宽度方向Y上的两侧分别设有电池排300时，宽度方向Y两侧的电池排300在排放组件10的长度方向X上正对，即其中一侧的电池排300中的多个电池单体200与另外一侧的电池排300中的多个电池单体200沿排放组件10的宽度方向Y一一正对，从而可以进一步提高空间利用率，提高电池1000的能量密度。
或者可选地，当排放组件10的宽度方向Y上的两侧分别设有电池排300时，宽度方向Y两侧的电池排300在排放组件10的长度方向X上错开，即其中一侧的电池排300中的多个电池单体200与另外一侧的电池排300中的多个电池单体200沿排放组件10的宽度方向Y一一斜对，从而可以较为有效地避免热失控时的对喷问题。
在一些具体示例中，如图33所示，排放组件10的宽度方向Y上的至少一侧设有沿排放组件10的高度方向Z依次排列的多个电池排300，由此，排放组件10可以用于更多数量的电池单体200排放，进一步提高结构紧凑性和空间利用率，提高电池1000的能量密度。
例如可选地，如图33所示，宽度方向Y同侧的多个电池排300在排放组件10的长度方向X上正对，即同侧的其中一个电池排300中的多个电池单体200与另一个电池排300中的多个电池单体200沿排放组件10的高度方向Z一一正对，从而可以进一步提高空间利用率，提高电池1000的能量密度。
或者可选地，宽度方向Y同侧的多个电池排300在排放组件10的长度方向X上错开，即同侧的其中一个电池排300中的多个电池单体200与另一个电池排300中的多个电池单体200沿排放组件10的高度方向Z一一斜对，这里不作赘述。
当排放组件10的宽度方向Y上的至少一侧设有沿排放组件10的高度方向Z依次排列的多个电池排300时，在一些实施例中，如图33所示，电池单体200的厚度方向与排放组件10的高度方向Z相同，从而可以在排放组件10的高度方向Z上容纳更多排电池排300，从而可以进一步提高空间利用率，提高电池1000的能量密度，有效解决了高能量密度的电池1000带来的安全失效风险。
此外，通过上述设置，还可以降低电池单体200相对于箱体100的高度，从而降低电池单体200的排放位置(如防爆阀或薄弱处)相对于箱体100的高度，进而能够有效降低电池单体200喷发的位置高度，使得排放物在高度方向Z上的影响范围较小，以减小扩散区域，提高电池1000整体的安全性能。
需要说明的是，宽度方向Y同侧所设置的电池排300的数量不限，例如排数可以少于各电池排300所包括的电池单体200的数量，例如可以为1排、2排或3排，从而可以减小由于排数较多造成的挤压力，减轻电池单体200所受外界挤压力，进而降低电池单体200***喷发的剧烈程度，提高安全性能。另外，当排放组件10的宽度方向Y侧面具有换热部时，如此排列的电池单体200可以使得换热组件同时为更多数量的电池单体200冷却散热。
在本申请的一些实施例中，如图37和图42所示，电池单体200的朝向排放组件10的一侧壁面为第一端面2001，第一端面2001具有泄压区域2002，例如，泄压区域2002可以是防爆阀或者薄弱部等，在热失控情况下，电池单体200可冲破泄压区域2002向排放组件10内排出排放物，通过将泄压区域2002朝向排放组件10设置，可以缩短排放路径，降低高温排放物冲击其他电池单体200造成二次伤害，提高安全性。
在一些实施例中，如图37所示，电池单体200的电连接端2004设于电池单体200的除第一端面2001以外的其他壁面上，例如电连接端2004可以为极耳、电极端子等。由此，通过将电连接端2004与泄压区域2002设于不同壁面，可以拉远电连接端2004与泄压区域2002之间的距离，降低从泄压区域2002喷出的排放物对电连接端2004造成的不良热影响以及绝缘失效的概率。
例如在一个具体示例中，如图37所示，电池单体200的背离排放组件10的一侧壁面为第二端面2003，电池单体200的电连接端2004设于第二端面2003。即泄压区域2002与电连接端2004分别设于电池单体200的相对两侧，且电连接端2004背离排放组件10设置，从而可以更好地拉远电连接端2004与泄压区域2002之间的距离，降低从泄压区域2002喷出的排放物对电连接端2004造成的不良热影响以及绝缘失效的概率。
此外，在一些示例中，当电池单体200为裸电芯采用卷绕的方式形成时，便于在卷绕轴向两端分别设置电连接端2004和泄压区域2002，可以缩短电连接端2004的引出路径，并且，还可以使得排气更顺畅。
在一些实施例中，如图37所示，第一端面2001和第二端面2003为电池单体200的长度两侧端面，当电池单体200的长度方向X沿水平方向延伸，厚度方向沿竖向延伸且为电池1000的高度方向F3时，将电池单体200的电连接端2004设于第二端面2003，将泄压区域2002设于第一端面2001，可以降低电池单体200在电池1000的高度方向F3上的空间占用率，使得电池1000整体在高度方向Z上结构更为 紧凑，有利于降低电池1000的整体高度尺寸，当将电池1000安装用车辆的底盘时，有利于解决底盘离地间隙的问题，减少由于车辆底盘过低使得电池容易磕碰刮擦的问题，使得电池1000使用寿命更长。
此外，当排放组件10的朝向电池单体200的一侧为换热部，且换热部内流通冷却介质时，可以利用换热部对电池单体200的泄压区域2002以及排放物有效降温，降低热失控蔓延的概率，而且，一旦冷却介质泄露，泄露处与电池单体200的电连接端2004也相距较远，安全性较高。
当然，本申请不限于此，当泄压区域2002设于电池单体200的长度一端时，例如还可以将电池单体200的电连接端2004设于电池单体200的厚度侧壁面，从而可以降低电连接难度。
本申请还不限于此，在一些实施例中，电池单体200的电连接端2004也可以同时设于第一端面2001，即电连接端2004与泄压区域2002位于电池单体200的同侧，此时，可以在电连接端2004与排放组件10之间设置绝缘件，从而避免排放物引发绝缘失效的问题。
在本申请的一些实施例中，电池单体200的固定方式不限，例如可以安装于排放组件10，从而便于电池单体200的安装，且保证电池单体200向排放组件10的排放可靠性，提高安全性。需要说明的是，电池单体200与排放组件10的连接方式不限，例如电池单体200可以直接粘贴于排放件1，从而提高连接效率。
需要说明的是，根据本申请实施例的电池1000的具体构成不限于此，例如结合图42，还可以包括设于电池排300中每相邻两个电池单体200之间的隔热件400，以及设于电池排300的长度两端的端板500等，这里不作赘述。此外，需要说明的是，根据本申请实施例的电池100所包括的分隔梁30、电池排300等的数量和排布不限，可以根据实际要求具体设定，这里不作赘述。
下面，参照附图，描述根据本申请第四方面实施例的电池1000。
如图3-图4所示，电池1000包括：排放件1、电池排300和防护件2。
排放件1为长条形结构且排放件1内形成有排放腔11，排放件1的宽度方向上的两侧壁面12上分别形成有进口区域13，排放腔11适于通过进口区域13接收电池单体200排出的排放物。
排放件1的宽度方向上的两侧分别设有电池排300，电池排300包括沿排放件1的长度方向依次排列的多个电池单体200，电池单体200的朝向排放件1的一侧具有泄压区域2002，每个电池单体200分别对应一个泄压区域2002设置。
防护件2设于排放件1内，防护件2与壁面12内外间隔开设置且遮挡进口区域13以至少用于阻挡排放物中的火焰，并在防护件2与壁面12之间形成连通进口区域13与排放腔11的连通通道R以使排放物中的气体可进入排放腔11。
值得说明的是，本文所述的“与壁面12内外间隔开设置”指的是，沿壁面12的厚度方向、与壁面12间隔开设置。
当发生热失控时，电池单体200产生的排放物如火焰、烟雾或气体可通过进口区域13进入排放件1内，通过防护件2的阻挡，能够对排放物中的火焰有效隔离，改善热扩散问题，从而避免热扩散引起其他电池单体200受到热失控的影响，有效避免了二次伤害。
并且，由于防护件2位于排放件1内，防护件2不会占用排放件1外的空间，使得排放件1与电池单体200的配合可以更加紧凑。而且，位于排放件1内的防护件2可以获得排放件1的保护，不易脱落、磕碰损坏等，从而可以提升防护件2的防护可靠性。此外，将防护件2设于排放件1内，无需对电池单体200进行改造，从而保证了电池单体200的能量密度。
需要说明的是，根据本申请第四方面实施例的电池1000可以包括传统的箱体，也可以不包括传统的箱体。此外，需要说明的是，根据本申请第四方面实施例的电池1000中的防护件2的具体可选实施例，在不矛盾的前提下，可以参考根据本申请第一方面实施例的排放组件10中的防护件2的实施例，根据本申请第四方面实施例的电池1000中的电池单体200的具体可选实施例，在不矛盾的前提下，可以参考根据本申请第三方面实施例的电池1000中的电池单体200的实施例。为简化描述，这里不作赘述。

如图43所示，根据本申请实施例的用电装置2000，包括根据本申请任一实施例的电池1000，电池1000用于为用电装置2000提供电能。由此，可以提高用电装置2000的安全性。
需要说明的是，根据本申请实施例的用电装置2000的类型不限，例如可以是车辆、手机、便携式设 备、笔记本电脑、轮船、航天器、电动玩具和电动工具等等。车辆可以是燃油汽车、燃气汽车或新能源汽车，新能源汽车可以是纯电动汽车、混合动力汽车或增程式汽车等；航天器包括飞机、火箭、航天飞机和宇宙飞船等等；电动玩具包括固定式或移动式的电动玩具，例如，游戏机、电动汽车玩具、电动轮船玩具和电动飞机玩具等等；电动工具包括金属切削电动工具、研磨电动工具、装配电动工具和铁道用电动工具，例如，电钻、电动砂轮机、电动扳手、电动螺丝刀、电锤、冲击电钻、混凝土振动器和电刨等等。
例如，如图43所示，当电池1000用于车辆时，电池1000可以设置在车辆的底部或头部或尾部。电池1000可以用于车辆的供电，例如，电池1000可以作为车辆的操作电源。车辆还可以包括控制器和马达，控制器用来控制电池1000为马达供电，例如，用于车辆的启动、导航和行驶时的工作用电需求。在本申请一些实施例中，电池1000不仅仅可以作为车辆的操作电源，还可以作为车辆的驱动电源，代替或部分地代替燃油或天然气为车辆提供驱动动力。
