节能减排是汽车产业可持续发展的关键。在这种情况下，电动车辆由于其节能环保的优势成为汽车产业可持续发展的重要组成部分。而对于电动车辆而言，电池技术又是关乎其发展的一项重要因素。
随着电池技术的不断发展，对电池的性能提出了更高的要求，希望电池能够同时考虑多方面的设计因素。
发明内容
本申请提供一种电池、用电装置、制备电池的方法和制备电池的装置，以提高电池的安全性。
第一方面，提供了一种电池，包括：电池单体；箱体；和分隔组件，用于将所述箱体分隔成第一收纳部和第二收纳部，所述第一收纳部用于收纳电气部件，所述第二收纳部用于收纳所述电池单体，在所述分隔组件形成有连通部，所述电气部件与所述电池单体经由连接部件电连接，所述连接部件贯通于所述连通部中，所述分隔组件具有相连的第一分隔部件和第二分隔部件，通过装配所述第一分隔部件和所述第二分隔部件而形成所述连通部。
在电池中，利用箱体收纳电池单体和高压、低压的电气部件。当电池单体发生破坏等情况下，从电池单体泄放的高温、高压的排放物可能对电气部件造成不良影响，甚至可能导致起火、***等问题。
本申请实施例的技术方案，将箱体利用分隔组件分隔为收纳电气部件的第一收纳部和收纳电池单体的第二收纳部，由此，即使电池单体发生破坏而喷发出高温、高压的排放物，也能够利用分隔组件阻挡该排放物，防止对电气部件的影响，增加电池的安全性。而且，由于分隔部件由第一分隔部件和第二分隔部件形成，能够提高分隔组件的安装性能，能够高效地生产具有分隔组件的箱体。为了将第一收纳部中收纳的电气部件与第二收纳部中收纳的 电池单体电连接，需要在分隔组件形成连通部，使电连接的部件贯穿该连通部。本申请中，连通部通过装配第一分隔部件和第二分隔部件而形成。由此，与直接在一体的分隔组件中挖出通孔等的形成方式相比，能够直观且简单地观察到连通部的状态，且能够便于将连接部件稳定地设置于连通部，从而能够提高分隔组件以及整个箱体的装配性能，且提高生产率。
在一些实施例中，所述第一分隔部件和所述第二分隔部件以可拆卸的方式连接。由此，能够方便地拆分第一分隔部件和第二分隔部件。而且，能够将第一分隔部件和第二分隔部件分别与箱体的上盖和箱壳安装，能够进一步提高分隔组件的安装和拆卸性能。
在一些实施例中，所述第一分隔部件和所述第二分隔部件中的一者设置有凹槽，所述凹槽的端部具有开口，通过装配所述第一分隔部件和所述第二分隔部件，所述开口被封闭并形成所述连通部。
在一些实施例中，所述凹槽沿第一方向贯穿所述第一分隔部件和所述第二分隔部件中的一者。
在一些实施例中，所述开口沿第二方向设置于所述第一分隔部件和所述第二分隔部件中的一者的端部，所述第二方向与所述第一方向垂直。
由此，在未将第一分隔部件和第二分隔部件安装在一起时，能够清楚地观察到凹槽内的状态，能够简单地在凹槽中放置连接部件，并且仅通过将第一分隔部件和第二分隔部件配合安装，就能够将一个分隔部件的凹槽的开口利用另一个分隔部件的平坦的端面封闭而形成连通部，且能够稳定地保持连接部件。
在一些实施例中，在所述第一分隔部件和所述第二分隔部件均形成有凹槽，通过装配所述第一分隔部件和所述第二分隔部件，所述第一分隔部件的凹槽和所述第二分隔部件的凹槽相对配置，而形成所述连通部。由此能够提高第一分隔部件和第二分隔部件的通用性，安装的操作者不需要为了确认两个分隔部件的上下位置关系而耗费时间，能够更简便地安装分隔组件。
在一些实施例中，所述箱体具有相连的上盖和箱壳，所述第一分隔部件与所述上盖连接，所述第二分隔部件与所述箱壳连接。由此明确在将箱体以上盖处于上方的方式立式设置时，第一分隔部件位于上方，第二分隔部件位于下方。
在一些实施例中，所述上盖包括第一盖和第二盖，所述第一盖、所述分 隔组件和所述箱壳包围的空间形成所述第一收纳部，所述第二盖、所述分隔组件和所述箱壳包围的空间形成所述第二收纳部。在一些实施例中，所述第一盖和所述第二盖相互分离设置。由于利用分隔组件将箱体内的空间分隔成了相互独立的第一收纳部和第二收纳部，且第一盖和第二盖分离设置，因此，在需要对电气部件进行维护和更换时，仅将第一盖卸下即可，能够减少繁琐的操作，节省操作空间。
在一些实施例中，所述第一分隔部件以可拆装的方式密封固定于所述第一盖和所述第二盖。由此明确第一分隔部件安装于第一盖和第二盖两者，确保能够利用一个分隔组件将箱体内的空间分隔为第一收纳部和第二收纳部。在第一盖与第二盖之间的高度不同时，能够在第一分隔部件的与第一盖固定的部分和与第二盖固定的部分之间形成高度差。而且，第一分隔部件与第一盖和第二盖均密封。由此，能够防止第二收纳部中的电池单体发生破坏而喷发出高温高压的排放物时，从第一分隔部件与第一盖和第二盖的连接处泄漏至箱体的外部，从而能够提高电池整体的安全性。
在一些实施例中，所述第二分隔部件与所述箱壳一体形成。由此能够在原料阶段提供已形成有第二分隔部件的箱体，从而提高分隔组件的加工和装配效率。
在一些实施例中，所述第二分隔部件以可拆装的方式固定于所述箱壳。由此能够增加装配的自由度。例如，能够将第一分隔部件和第二分隔部件预先装配在一起后再装配于箱体，也能够在将第二分隔部件安装于箱壳之后，相对于第二分隔部件安装第一分隔部件。第二分隔部件也可以与箱壳密封固定。
在一些实施例中，在所述连通部内设置有安装部件，所述安装部件用于安装所述连接部件。由此能够利用安装部件更稳定地设置连接部件，提高装配可靠性。
在一些实施例中，所述安装部件用于将所述连接部件与所述分隔组件绝缘。本申请中的连接部件包括高压线缆，通过利用安装部件使连接部件与分隔组件绝缘，能够进一步提高连接部件的绝缘安全性。
在一些实施例中，所述安装部件与所述连通部卡合，并且所述安装部件形成有卡扣凹部，所述卡扣凹部用于固定所述连接部件。由此，安装部件与连通部卡合并且卡扣固定连接部件，能够简便且稳定地安装连接部件。
在所述第一分隔部件和所述第二分隔部件中的一者形成有定位凸部，在另一者形成有定位凹部，所述定位凸部和所述定位凹部沿所述分隔组件的延伸方向设置，通过将所述定位凸部和所述定位凹部嵌合而装配所述第一分隔部件和所述第二分隔部件。即，为了保证第一分隔部件和第二分隔部件的定位精度，在分隔部件设置有用于定位的凹部和凸部。由此能够提高分隔组件的装配精度。

本申请的实施例所提到的电池是指包括多个电池单体以提供更高的电压和容量的单一的物理模块。例如，本申请中所提到的电池可以包括电池模块或电池包等。
电池单体包括电极组件和电解液，电极组件包括正极片、负极片和隔离膜。电池单体主要依靠金属离子在正极片和负极片之间移动来工作。正极片包括正极集流体和正极活性物质层，正极活性物质层涂覆于正极集流体的表面，未涂敷正极活性物质层的集流体凸出于已涂覆正极活性物质层的集流体，未涂敷正极活性物质层的集流体作为正极极耳。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。负极片包括负极集流体和负极活性物质层，负极活性物质层涂覆于负极集流体的表面，未涂敷负极活性物质层的集流体凸出于已涂覆负极活性物质层的集流体，未涂敷负极活性物质层的集流体作为负极极耳。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。为了保证通过大电流而不发生熔断，正极极耳的数量为多个且层叠在一起，负极极耳的数量为多个且层叠在一起。隔离膜的材质可以为PP或PE等。此外，电极组件可以是卷绕式结构，也可以是叠片式结构，本申请实施例并不限于此。
电池技术的发展要同时考虑多方面的设计因素，例如，能量密度、循环寿命、放电容量、充放电倍率等性能参数，另外，还需要考虑电池的安全性。
目前，电动车辆的电池往往需要几十甚至上千个电池单体构成。在电池的箱体中容纳电池单体以及各种电气部件。该电气部件包括汇流部件、高低压线等。在电池由于存在异常状况而发生破坏时，可能会从电池单体泄放出高温、高压的排放物。这样的排放物如果直接喷泄于电气部件，会对电气部件造成不良影响，甚至可能导致起火、***等事故。
鉴于此，本申请提供了一种电池，包括：电池单体；箱体；和分隔组件，用于将所述箱体分隔成第一收纳部和第二收纳部，所述第一收纳部用于收纳电气部件，所述第二收纳部用于收纳所述电池单体，在所述分隔组件形成有连通部，所述电气部件与所述电池单体经由连接部件电连接，所述连接部件贯通于所述连通部中，所述分隔组件具有相连的第一分隔部件和第二分隔部件，通过装配所述第一分隔部件和所述第二分隔部件而形成所述连通部。
通过将箱体利用分隔组件分隔为收纳电气部件的第一收纳部和收纳电池单体的第二收纳部，即使电池单体发生破坏而喷发出高温、高压的排放物，也能够利用分隔组件阻挡该排放物，防止其对电气部件的影响，增加电池的安全性。而且，由于分隔部件由第一分隔部件和第二分隔部件形成，能够提高分隔组件的安装性能，能够高效地生产具有分隔组件的箱体。为了将第一收纳部中收纳的电气部件与第二收纳部中收纳的电池单体电连接，需要在分隔组件形成连通部，使电连接的部件贯穿该连通部。本申请中，连通部通过装配第一分隔部件和第二分隔部件而形成。由此，与直接在一体的分隔组件中挖出通孔等的形成方式相比，能够直观且简单地观察到连通部的状态，并且能够便于将连接部件稳定地设置于连通部，提高连接部件的安装操作性。从而能够提高分隔组件以及整个箱体的装配性能，且提高生产率。
本申请一个实施例提供了一种用电装置，电池用于提供电能。
本申请实施例描述的技术方案均适用于各种使用电池的装置，例如，手机、便携式设备、笔记本电脑、电瓶车、电动玩具、电动工具、电动车辆、船舶和航天器等，例如，航天器包括飞机、火箭、航天飞机和宇宙飞船等。
应理解，本申请实施例描述的技术方案不仅仅局限适用于上述所描述的设备，还可以适用于所有使用电池的设备，但为描述简洁，下述实施例均以电动车辆为例进行说明。
例如，如图1所示，为本申请一个实施例的一种车辆100的结构示意图，车辆100可以为燃油汽车、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。车辆100的内部可以设置马达2，控制器3以及电池1，控制器3用来控制电池1为马达2的供电。例如，在车辆100的底部或车头或车尾可以设置电池1。电池1可以用于车辆100的供电，例如，电池1可以作为车辆100的操作电源，用于车辆100的电路***，例如，用于车辆100的启动、导航和运行时的工作用电需求。在本申请的另一 实施例中，电池1不仅仅可以作为车辆100的操作电源，还可以作为车辆100的驱动电源，替代或部分地替代燃油或天然气为车辆100提供驱动动力。
为了满足不同的使用电力需求，电池1可以包括多个电池单体10，其中，多个电池单体10之间可以串联或并联或混联，混联是指串联和并联的混合。
例如，如图2所示，为本申请一个实施例的电池1的立体结构示意图。电池1包括箱体20，箱体20内部为中空结构，在箱体20内容纳电池单体10(表示于图3)。如图2所示，箱体20可以包括两部分，这里分别称为上盖21和箱壳22。上盖21和箱壳22扣合在一起。上盖21和箱壳22的形状可以根据多个电池单体10组合的形状而定。例如，可以是上盖21和箱壳22均为中空长方体且各自只有一个面为开口面，上盖21的开口和箱壳22的开口相对设置，并且上盖21和箱壳22相互扣合形成具有封闭腔室的箱体20。也可以是上盖21为具有开口的长方体而箱壳22为板状，或者箱壳22为具有开口的长方体而上盖21为板状，上盖21和箱壳22相对设置并扣合而形成具有封闭腔室的箱体20。
如图3所示，为图2中去除上盖21后的状态的结构示意图。电池1具有多个电池单体10，多个电池单体10能够沿第一方向X和第二方向Y排列，其中第一方向X与第二方向Y正交。即，电池1中的多个电池单体10可以排列成矩阵状的结构。可选地，电池1也可以只有一个电池单体10、或者具有多个沿第一方向X排列的电池单体1、或者具有多个沿第二方向Y排列的电池单体10。多个电池单体10相互并联或串联或混联组合后，置于上盖21和箱壳22扣合后形成的箱体20内。
如图3所示，利用分隔组件30能够将箱体20分隔成第一收纳部40和第二收纳部41，第一收纳部40用于收纳电气部件42，第二收纳部41用于收纳电池单体10。如图2所示，上盖21包括第一盖210和第二盖211。由此，第一盖210、分隔组件30和箱壳22包围的空间形成了第一收纳部40，第二盖211、分隔组件30和箱壳22包围的空间形成了第二收纳部41。第一盖210和第二盖211相互分离设置。为了将第一收纳部40和第二收纳部41连通，在分隔组件30形成有连通部33，电气部件42与电池单体10经由连接部件34电连接，连接部件34贯通于连通部33中。
由于本申请中将箱体20利用分隔组件30分隔为收纳电气部件42的第一收纳部40和收纳电池单体10的第二收纳部41，即使电池单体10发生破坏而 喷发出高温、高压的排放物，也能够利用分隔组件30阻挡该排放物，防止对电气部件42造成冲击，能够增加电池1的安全性。
而且，由于利用第一盖210、第二盖211、分隔组件30将箱体20内的空间分隔成了相互独立的第一收纳部40和第二收纳部41，且第一盖210和第二盖211分离设置，在需要对电气部件42进行维护和更换时，仅将第一盖210卸下即可，能够减少繁琐的操作，节省操作空间。
如图3所示，分隔组件30具有第一分隔部件31和第二分隔部件32。第一分隔部件31与上盖21连接，第二分隔部件32与箱壳22连接。即，在将箱体20在第三方向Z上以上盖21处于上方的方式设置时，第一分隔部件31位于上方，第二分隔部件32位于下方。
第一分隔部件31以可拆装的方式密封固定于第一盖210和第二盖211。在第三方向Z上，第一盖210与第二盖211的高度不同时，能够在第一分隔部件31的与第一盖210固定的部分和与第二盖211固定的部分之间形成高度差。而且，第一分隔部件31与第一盖210和第二盖211均密封，例如涂有密封胶或密封衬件等。由此，能够防止第二收纳部41中的电池单体10发生破坏而喷发出高温高压的排放物时，从第一分隔部件31与第一盖210和第二盖211的连接处泄漏至箱体20的外部，从而能够提高电池1整体的安全性。
第二分隔部件32可以与箱壳22一体形成。由此能够在原料阶段提供已形成有第二分隔部件32的箱体20，从而提高分隔组件30的加工和装配效率。或者，第二分隔部件32也可以以可拆装的方式固定于箱壳22。由此能够增加装配的自由度。例如，能够将第一分隔部件31和第二分隔部件32预先装配在一起后再装配于箱体20，也能够在将第二分隔部件32安装于箱壳22之后，相对于第二分隔部件32安装第一分隔部件31。第二分隔部件32也可以密封固定于箱壳22。
如图4(a)所示，为分隔组件30的示意结构图。在图4(a)中表示了在分隔组件30中具有供高压连接部件和低压连接部件分别通过的两个连通部33的结构。如图4(b)所示，放大表示分隔组件30中的一个连通部33，另一个连通部33的结构也相似，因此省略说明。另外，分隔组件30中的连通部33的个数没有限定，能够根据连接部件34的设计而设置。
如图4(b)所示，分隔组件30具有第一分隔部件31和第二分隔部件32。为了将第一收纳部40和第二收纳部41连通，在分隔组件30形成有连通部33， 连接部件34沿第一方向X贯通于连通部33中。第一分隔部件31和第二分隔部件32以可拆卸的方式连接。由此，能够方便地拆分第一分隔部件31和第二分隔部件32。连通部33通过装配第一分隔部件31和第二分隔部件32而形成。
在一体的分隔组件中开出通孔等的形成连通部的方式中，操作者需要凭借经验将连接部件***连通部中，无法直观地看到连通部内部的状况，也无法确定是否稳定地固定了连接部件。而本申请中，使连通部33通过装配第一分隔部件31和第二分隔部件32而形成，从而能够直观且简单地观察到连通部33的状态，且能够便于将连接部件34稳定地设置于连通部33，从而能够提高分隔组件30以及整个箱体20的装配性能，提高生产率。
作为装配第一分隔部件31和第二分隔部件32而形成连通部33的方式，例如如图4(b)所示，在第二分隔部件32中设置有凹槽35，凹槽35的端部具有开口36，凹槽35沿第一方向X贯穿第二分隔部件32，开口36沿第二方向Y设置于第二分隔部件32的端部。其中，第二方向Y是分隔组件30的延伸方向，且第二方向Y与第一方向X正交。通过装配第一分隔部件31和第二分隔部件32，第二分隔部件32的凹槽35的开口36被第一分隔部件31的平坦的端面封闭而形成连通部33。
在连通部33内设置有安装部件37，安装部件37用于安装连接部件34。而且，安装部件37能够将连接部件34与分隔组件30绝缘。由此能够进一步提高连接部件34的绝缘安全性。
如5(a)和图5(b)中表示装配第一分隔部件31和第二分隔部件32而形成连通部33的其它方式。
如图5(a)所示，在第一分隔部件31中设置有凹槽35，凹槽35的端部具有开口36，凹槽35沿第一方向X贯穿第一分隔部件31，开口36沿第二方向Y设置于第一分隔部件31的端部。由此，通过装配第一分隔部件31和第二分隔部件32，第一分隔部件31的凹槽35的开口36被第二分隔部件32的平坦的端面封闭而形成连通部33。
如图5(b)所示，在第一分隔部件31和第二分隔部件32中均设置有凹槽35，各凹槽35的端部均具有开口36，凹槽35沿第一方向X贯穿第一分隔部件31和第二分隔部件32，开口36沿第二方向Y设置于第一分隔部件31和第二分隔部件32的端部。由此，通过装配第一分隔部件31和第二分隔部 件32，第一分隔部件31的凹槽35和第二分隔部件32的凹槽35相对配置，而形成所述连通部33。
在图4(b)、图5(a)所示的实施例中，未将第一分隔部件31和第二分隔部件32安装在一起时，都能够清楚地观察到凹槽35内的状态，能够简单地在凹槽35中放置连接部件34，并且仅通过将第一分隔部件31和第二分隔部件32配合安装，就能够将一个分隔部件的凹槽35的开口利用另一个分隔部件的平坦的端面封闭而形成连通部33，且能够稳定地保持连接部件34。
特别是在图5(b)所示的实施例中，通过在第一分隔部件31和第二分隔部件32均形成有凹槽35，通过装配第一分隔部件31和第二分隔部件32，第一分隔部件31的凹槽35和第二分隔部件32的凹槽35相对配置，而形成连通部33。由此，能够提高第一分隔部件31和第二分隔部件32的通用性，安装的操作者不需要为了确认两个分隔部件的上下位置关系而耗费时间，能够更简便地装配分隔组件30。
在图4(a)和图4(b)中表示了安装部件37的结构，根据图6(a)～图6(d)进一步说明安装部件37的具体结构。安装部件37与连通部33卡合，而且安装部件37形成有卡扣凹部38，卡扣凹部38用于固定连接部件34。由此，如图6(a)～(d)所示，安装部件37的外表面与连通部33卡合，并且安装部件37的内表面形成与连接部件34的外形形状匹配的卡扣凹部38，以卡扣固定连接部件34，从而能够简便且稳定地安装连接部件34并加强绝缘性。在图6(a)中表示了连通部33为方孔且连接部件34的外形为方形时的安装部件37的结构。在图6(b)中表示了连通部33为方孔且连接部件34的外形为弧形时的安装部件37的结构。在图6(c)中表示了连通部33为弧形孔且连接部件34的外形为弧形时的安装部件37的结构。在图6(d)中表示了连通部33为弧形孔且连接部件34的外形为方形时的安装部件37的结构。连通部33和连接部件34的形状并不限于图示的方形和弧形，也可以形成为任意的形状。只要安装部件37的外表面与连通部33卡合、且卡扣凹部38与连接部件34卡合即可。
如图7所示，为第一分隔部件31和第二分隔部件32间的定位结构的示意图。在第一分隔部件31形成有定位凸部50，在第二分隔部件32形成有定位凹部51，定位凸部50和定位凹部51沿分隔组件30的延伸方向(即第二方向Y)设置，通过将定位凸部50和定位凹部51嵌合而定位第一分隔部件31 和第二分隔部件32。由此能够提高分隔组件30中的第一分隔部件31与第二分隔部件32之间的定位精度。另外，也可以是定位凹部51形成于第一分隔部件31、定位凸部50形成于第二分隔部件32。
如图8所示，为第一分隔部件31和第二分隔部件32装配完成的结构示意图。其中省略了连接部件34的图示。如图8所示，第一分隔部件31和第二分隔部件32利用螺栓52紧固固定。但分隔组件30的固定方式不限于此，只要能够将第一分隔部件31和第二分隔部件32牢固地固定，则可以是其它的方式，例如粘接、铆接等。
