导致电池燃烧的危险的内在原因，有电池自身缺陷因素，也有电池自身老化因素。电池自身缺陷因素：设计缺陷和生产缺陷都比较常见，如生产缺陷造成的内部偶发型短路等。电池自身老化因素：有的因为使用或放置时间老化，有的因为环境高温，造成内部析晶现象偶发型短路等。
导致电池燃烧的危险的外在原因，有电池不当使用因素，也有电池意外事故因素。电池不当使用因素：有的因为使用过程中外部短路；也有可充电池，使用过程中过充等。电池意外事故因素：比如使用中发生电池碰撞事故、电池穿刺事故、电池受到挤压、或者事故造成的电池高温、电池破损等。
电池燃烧前，会有一个持续蓄热升温的过程，该升温可持续至电池燃烧熄灭；电池正常使用过程中，虽然温度也会升高，但是被动散热量会随温度升高、温差增大而增大，或者主动散热的介入，总会被限制在一个合理的温度范围；上述合理的温度范围的具体参数一般由电池供应商提供，用户应该在上述合理的温度范围最高温度以下使用电池；上述合理的温度范围的最高温度被称之为正常工作最高温度；当持电池续蓄热升温，超过上述合理的温度范围，被称之为电池异常高温，或被称之为电池过热。
电池异常高温，直至超过燃点，电池会发生一般的燃烧、***、爆燃。区别于一般的燃烧，所谓***就是电池极其剧烈的燃烧，期间电池体积瞬间增大而破裂。区别于一般的燃烧、***，爆燃就是电池一般的燃烧、***交替的发生。电池一般的燃烧、***、爆燃， 都属于广义的燃烧。本申请所述燃烧指广义的燃烧。
电池燃烧，过程可能是：一般的燃烧、***、先一般的燃烧再***、先***再一般的燃烧、先一般的燃烧再***后继续一般的燃烧等。
电池燃烧，可能造成设备的损坏，甚至人身危害。尤其是，当使用多个电池时，由于一个电池的燃烧，蔓延至其他电池燃烧，会造成更严重的设备损坏、人身危害。
现有的电池装置中，为了减少电池燃烧的危险造成的设备损坏、人身危害，采用：将电池原材料全部替换为新型难燃、阻燃材料，此方法尚存在诸如电池能量密度、电池材料成本等研发推广困难，且目前上述难燃、阻燃材料的性能尚不能全部达到不可燃的程度。
或采用：为电池设置灭火装置，考虑到灭火装置的体积、重量、成本等因素，都对灭火装置和其容纳的灭火剂的容量有限制，此方法很难将火彻底熄灭，并且灭火剂释放后电池留在原位，灭火后仍有复燃的危险，进而造成设备损坏和人身危害。
或采用：为电池设置包覆阻燃材料装置，考虑到材料的厚度、重量、成本等因素，都对阻燃效果有限制，此方法电池留在原位燃烧，有可能期间发生***破坏阻燃材料，或者有可能烧透阻燃材料，进而造成设备损坏和人身危害。

电池燃烧危险，可能造成设备的损坏，甚至人身危害。尤其是，当使用多个电池时，由于一个电池的燃烧，蔓延至其他电池燃烧，会造成更严重的设备损坏、人身危害。
发明人研究发现，电池即将发生燃烧危险，常有：电池变型、电池泄露、异常高温、电池电压异常改变、电池电流异常改变等异常现象；电池发生燃烧危险时，过程可能是：燃烧、***、先燃烧再***、先***再燃烧、先燃烧再***后继续燃烧等；电池即将发生燃烧危险，或发生燃烧危险时，电池输出的电压、电流亦会异常变化，比如：被导体穿刺的电池燃烧之前，可能电压、电流急剧减小至近零；电池通过与其他电池串、并联作为电池组的一部分时，即将发生燃烧时电压、电流急剧增大甚至超出额定值、也可能出现负值。
本实施例提供的技术方案中，通过将***装置设置在电池安装位，所述电池发生燃 烧，或所述电池发生上述异常现象时，将所述电池从所述电池安装位炸离，以解决减少所述电池燃烧导致的设备损坏、人身危害的问题。
图1为本实施例1提供的电池装置整体结构示意图，图2为本实施例1提供的电池装置的第一电池安装位和第二电池安装位均未安装电池的整体结构示意图。请结合参照图1和图2，本实施例提供了一种电池装置：包括装置主体和电池。
所述装置主体设置有至少一个电池安装位，包括第一电池安装位、可选的第二电池安装位。
在所述第一电池安装位的安装位主体上，设置有***装置，所述***装置上安装有所述电池。
所述***装置，设置有对所述电池燃烧敏感的***，所述***被引爆后可将所述电池炸离。
如果所述电池燃烧将引爆所述***，将所述电池炸离所述装置主体。
本实施例技术方案至少具有以下优点：
所述电池一旦发生燃烧，即刻被炸离；所述电池直接安装于所述***装置上，结构简单；除了极少数低感度***，绝大多数***都可被燃烧引爆，该方案非常助于实现整体的低成本。
可选的，提高所述***机械感度，使其受到所述电池变形导致的挤压时***，将所述电池炸离所述装置主体。
本实施例该可选技术方案至少具有以下优点：
所述电池一旦变形，变形尚未引发燃烧时，所述***只要受到该变形导致的挤压时便被挤爆，因为所述电池变形可能是燃烧前兆，也可能导致燃烧，所以提前炸离所述电池避免其在所述安装位主体上燃烧。
可选的，提高所述***热感度，所述电池异常高温时便被引爆，将所述电池炸离所述装置主体；虽然通过调整所述***成分、成分比例等方式，将热感度调整刚达到电池异常高温即可实现本实施例可选技术方案功能，但是由于这些方式很难精确控制触发温度，可能会带来误触发，且考虑到所述电池温升刚达到电池异常高温的初期一般不会对所述第一电池安装位有损害；因此，通常所述***热感度温度设置较电池异常高温初期温度更高，只要不高于所述电池可能损害所述第一电池安装位的温度所述***被引爆即可。
本实施例该可选技术方案至少具有以下优点：
所述电池一旦产生异常高温，甚至尚未燃烧时，所述***只要受到该异常高温便被***，因为异常高温可能是燃烧前兆，也可能导致燃烧，所以提前炸离所述电池避免其在所述安装位主体上燃烧。
可选的，所述***有雷酸汞成分，所述电池包装夹层中预置了少量锌铝镁粉，如果所述电池包装破损铝镁粉泄露，所述******，将所述电池炸离所述装置主体。
本实施例该可选技术方案至少具有以下优点：
所述电池一旦产生包装破损泄露，甚至尚未燃烧时，所述***只要接触预置的锌铝镁粉便被 引爆，因为所述电池包装破损可能是燃烧前兆，也可能导致燃烧，所以提前炸离所述电池避免其在所述安装位主体上燃烧。
进一步的，所述***装置，设置有引爆装置。
可选的，本实施例所述引爆装置对火花敏感：所述电池正常工作时，没有火花，所述电池燃烧时，火花触发所述引爆装置，所述引爆装置引爆所述***装置，将所述电池炸离。
可选的，本实施例所述引爆装置与温度有关：所述电池正常工作最高温度为t1，所述电池燃烧时，最高温度为t2；安全裕量Δt，Δt<t2-t1，Δt越小越高灵敏度，Δt越大越低误触发率；所述引爆装置设定温度预设值T，T>t1+Δt，当所述引爆装置温度达到或超过所述温度预设值T时，所述引爆装置引爆所述***装置，将所述电池炸离。
