在上述技术方案中，由于电池单体的自身的电连接部和自身的泄压部分别位于电池单体的不同表面上，有利于保证电池单体的电连接部和泄压部之间具有较大的间距，以有效避免在热失控等情况下，电池单体通过自身泄压部排放的排放物中的导电颗粒等流至自身电连接部造成绝缘失效、高压打火等问题，保证电池中各导电部件之间的爬电间隙，以避免发生短路问题。同时，电池单体的电连接部与同一电池组中另一电池排的泄压部并非相对设置，以便使得电池单体的电连接部免受其他电池单体通过泄压部排出的排放物的影响，即减小了电池单体通过泄压部排出的排放物对其他电池单体的电连接部的影响，保证了电池的使用安全性和可靠性。此外，由于同一电池组的两个电池排的电连接部相对设置，有利于实现同一电池组的两个电池排的电连接，从而有利于提高生产效率，并有利于对电连接位置实现集中保护等等。简言之，电池的电连接方便，热失控对电连接的影响较小。

在一些实施例中，多个所述电池组沿第三方向设置以构成多层电池组，所述第三方向垂直于所述第一方向和所述第二方向。在上述技术方案中，电池包括的电池单体的数量更多，电量较高。
在一些实施例中，所述多层电池组中所述电池组的数量小于所述电池排中所述电池单体的数量。在上述技术方案中，在保证电池排布置一定数量的前提下，便于减小电池排在高度方向上承受的挤压力，降低挤压力对电池单体在泄压排放排放物时的剧烈程度造成的影响。
在一些实施例中，所述多层电池组中所述电池组的数量为2～3。在上述技术方案中，在保证电池排布置一定数量的前提下，便于减小电池排在高度方向上承受的挤压力，降低挤压力对电池单体在泄压排放排放物时的剧烈程度造成的影响。

本申请中出现的“多个”指的是两个以上(包括两个)。
本申请中，电池是指包括一个或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组或电池包等。一些电池可以包括用于封装一个或多个电池单体或多个电池模组的箱体。箱体可以避免液体或其他异物影响电池单体的充电或放电。当然，还有一些电池可以不包括上述箱体，直接设置在用电装置的电池安装舱内。
本申请中，电池单体可以包括锂离子二次电池、锂离子一次电池、锂硫电池、钠锂离子电池、钠离子电池或镁离子电池等，本申请实施例对此并不限定。电池单体可呈圆柱体、扁平体、长方体或其它形状等，本申请实施例对此也不限定。电池单体一般按封装的方式分成三种：柱形电池单体、方形电池单体和软包电池单体，本申请实施例对此也不限定。
例如，电池单体可以包括外壳、电极组件和电解液，外壳用于容纳电极组件和电解液。电极组件由正极极片、负极极片和隔离膜组成。电池单体主要依靠金属离子在正极极片和负极极片之间移动来工作。正极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正极集流体凸出于已涂覆正极活性物质层的正极集流体，未涂敷正极活性物质层的正极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负极集流体凸出于已涂覆负极活性物质层的负极集流体，未涂敷负极活性物质层的负极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(polypropylene，聚丙烯)或PE(polyethylene，聚乙烯)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。
电池单体上可以设置极柱等与极耳相连，作为电池单体的电连接部。并且，电池单体上通常具有泄压部，在电池单体内压过大(例如热失控)时，泄压部用于释放电池单体内部物质(例如气体、液体、颗粒物等)，以降低电池单体的内部压力，避免电池单体内部过快加压，而导致电池单体爆燃等危险事故。例如，泄压部可以为防爆阀、防爆片等等。
例如图1和图2所示，一些用电装置A中，采用电池B进行供电，电池B包括箱体B1和电池单体B2，箱体B1包括上壳B11和下壳B12。传统技术中，电池单体通常将电连接部与泄压部设置于电池单体的同侧表面，然而在泄压部发生排放泄压以使电池单体释放内部压力时，电池单体的排放物中的导电颗粒容易移动至电连接部，并与其搭接形成内短路，或者降低电连接部之间的爬电间隙，导致发生高压打火等绝缘失效现象。
为了避免电池单体在释放内部压力时导致的绝缘失效问题，申请人发现，可以将电池单体的电连接部与泄压部分别设置于电池单体的不同端面上；但是，在电池中，为了使得电池具有合适的电压和容量，往往设置多个电池单体，且将多个电池单体呈多排放置，上述结构也仅能使得单各电池单体自身的电连接部远离自身的泄压部，当一各电池单体的泄压部朝向相邻的电池单体的电连接部设置时，仍然存在排放物中的导电颗粒容易移动至电连接部，或者降低导电部件间的爬电间隙，导致发生高压打火等绝缘失效现象。
基于此，申请人经过深入研究，提出了一种电池1000，包括至少一个电池组100，电池组100包括两个电池排10，每个电池排10均包括至少一各电池单体1，每个电池单体1的朝向同组另一电池排10的一侧设有电连接部11，每个电池单体1还设有泄压部12，泄压部12与电连接部11设于电池单体1的不同侧。
在上述这种结构的电池1000中，通过将电池单体1自身的泄压部12和自身的电连接部11分别设在电池单体1的不同端面上，以有效避免电池单体1通过泄压部12排出的排放物例如导电颗粒等流至电连接部11造成高压打火等绝缘失效现象，保证电池1000中各导电部件之间的爬电间隙，以避免发生内短路。
同时，电池单体1的电连接部11与同一电池组100中另一电池排10的泄压部12并非相对设置，以便使得电池单体1的电连接部11免受其他电池单体1通过泄压部12排出的排放物的影响，即减小了电池单体1通过泄压部12排出的排放物对其他电池单体1的电连接部11的影响，保证了电池1000的使用安全性和可靠性。
本申请实施例公开的电池1000可以用于、但不限用于车辆、船舶或飞行器等用电装置2000中，可以使具备本申请公开的电池1000等组成该用电装置2000的电源系统，以保证用电装置2000的使用安全性和可靠性。
例如，本申请实施例公开的用电装置2000可以是、但不限于是车辆、手机、平板、笔记本电脑、轮船、航天器、电动玩具和电动工具等等。车辆可以是燃油车辆、或燃气车辆、或新能源车辆、或轨道车辆，新能源车辆可以是纯电动车辆、混合动力车辆或增程式车辆等；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、电动车辆玩具、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。
下面，参考附图，描述根据本申请实施例的电池1000。
如图3所示，电池1000包括：至少一个电池组100，电池组100包括两个电池排10，每个电池排10均包括至少一各电池单体1，每个电池单体1的朝向同组另一电池排10的一侧设有电连接部11，每个电池单体1还设有泄压部12，泄压部12与电连接部11设于电池单体1的不同侧。本文所述的“同组”指的是同一电池组100。
结合图3-图6，电池单体1的朝向同一电池组100中另一电池排10的一侧表面为第一端壁131，电池单体1的电连接部11设置在第一端壁131上，而电池单体1的泄压部12设 置在电池单体1的除第一端壁131以外的其他壁面上。
由此，由于电池单体1的自身的电连接部11和自身的泄压部12分别位于电池单体1的不同表面上，有利于保证电池单体1的电连接部11和泄压部12之间具有较大的间距，以有效避免在热失控等情况下，电池单体1通过自身泄压部12排放的排放物中的导电颗粒等流至自身电连接部11造成绝缘失效、高压打火等问题，保证电池1000中各导电部件之间的爬电间隙，以避免发生短路问题。
同时，电池单体1的电连接部11与同一电池组100中另一电池排10的泄压部12并非相对设置，以便使得电池单体1的电连接部11免受其他电池单体1通过泄压部12排出的排放物的影响，即减小了电池单体1通过泄压部12排出的排放物对其他电池单体1的电连接部11的影响，保证了电池1000的使用安全性和可靠性。
更具体地说，同一电池组100中两个电池排10的电池单体1的电连接部11与电连接部11面对面设置，各电池单体1的泄压部12均不朝向其他任一电池单体1的电连接部11设置，同一电池排10中的各电池单体1的泄压部12均不朝向本电池排10中的任一电连接部11喷发，也不朝向同一电池组100中另一电池排10的任一电连接部11喷发，从而可以有效保证各电池单体1的电连接部11免受其他电池单体1排出的排放物的影响，保证了电池1000的使用安全性和可靠性。
此外，由于同一电池组100的两个电池排10的电连接部11相对设置，有利于实现同一电池组100的两个电池排10的电连接，从而有利于提高生产效率，并有利于对电连接位置实现集中保护等等。
根据本申请实施例的电池1000，通过将电池单体1的泄压部12和电连接部11分别设在电池单体1的不同表面上，可以有效避免电池单体1通过泄压部12排出的排放物中的导电颗粒等流至电连接部11造成高压打火等绝缘失效问题，保证了电池1000的使用安全性和可靠性。当本申请实施例公开的电池1000用于用电装置2000中时，用电装置2000的电源系统可以采用本申请公开的电池1000，从而可以提升用电装置2000的使用安全性和可靠性。
在一些实施例中，泄压部12设于电池单体1的背向同组另一电池排10的一侧。例如在图3-图5所示的示例中，电池单体1的朝向同一电池组100中另一电池排10的一侧为第一端壁131，电池单体1的背向同一电池组100中另一电池排10的一侧为第二端壁132，电连接部11设于第一端壁131，泄压部12设于第二端壁132。由此，可以进一步拉远电连接部11与泄压部12之间的距离，可以更好地保证电连接部11免受泄压部12排出的排放物的影响，即受影响概率更小，电池1000的使用安全性和可靠性更好。
在一些实施例中，泄压部12与电连接部11分置于电池单体1的长度两端。例如在图3-图5所示的示例中，电池单体1的长度方向指向同一电池组100中另一电池排10，电池单体1沿自身长度方向相对的两侧壁面分别为第一端壁131和第二端壁132，第一端壁131朝向同一电池组100中另一电池排10，电连接部11设于第一端壁131，泄压部12设于第二端壁132。由此，可以有效拉远电连接部11与泄压部12之间的距离，可以更好地保证电连接部11免受泄压部12排出的排放物的影响，即受影响概率更小，电池1000的使用安全性和可靠性更好。
当然，本申请不限于此，例如在本申请的其他实施例中，也可以将电池单体1的宽度方向指向同一电池组100中另一电池排10，此时，电连接部11则设于电池单体1的宽度方向 上的一侧壁面，或者，还可以将电池单体1的厚度方向指向同一电池组100中另一电池排10，此时，电连接部11则设于电池单体1的厚度方向上的一侧壁面，这里不作赘述。
在一些实施例中，例如图3-图5所示，泄压部12与电连接部11分置于电池单体1的水平方向上的两侧。也就是说，当电池1000在使用场景中，设置泄压部12的一侧壁面(例如第二端壁132)并非高于设置电连接部11的一侧壁面(例如第一端壁131)，这样，可以有效地避免泄压部12相对于电连接部11的位置过高，出现泄压部12喷发的排放物的扩散能力较强，引发排放物扩散至相对较低的电连接部11的问题，从而可以更好地避免电连接部11受泄压部12排出的排放物的影响。而且，将电连接部11和泄压部12沿水平方向对置，可以降低电池排10的高度，从而降低电池1000的整体高度。
在另外一些实施例中，例如图8所示，电池单体1的朝向同组(即同一电池组100)另一电池排10的一侧为第一端壁131，电池单体1的背向同组(即同一电池组100)另一电池排10的一侧为第二端壁132，电池单体1的连接在第一端壁131与第二端壁132之间的为周侧壁133，泄压部12设于周侧壁133。由此，电连接部11与泄压部12分别位于电池单体1的相邻侧，可以使得电连接部11与泄压部12之间具有一定的安全距离，降低泄压部12排出的排放物对电连接部11的影响，提高电池1000的使用安全性和可靠性。
在一些可选示例中，如图3-图5所示，每个电池排10均包括沿第一方向F1排列的多个电池单体1，同组的两个电池排10沿第二方向F2排列，电池单体1沿第二方向F2相对的两侧端壁分别为第一端壁131和第二端壁132，第一端壁131朝向同组(即同一电池组100)另一电池排10，第二端壁132背向同组(即同一电池组100)另一电池排10。其中，当电连接部11与泄压部12设于相对两侧时，电连接部11设于第一端壁131，泄压部12设于第二端壁132。
而当电连接部11与泄压部12分别位于电池单体1的相邻侧时，在一些可选示例中，结合图9，周侧壁133可以包括沿第三方向F3相对设置的第一侧壁1331和第二侧壁1332，当电连接部11与泄压部12分别位于电池单体1的相邻侧时，泄压部12可以设于第一侧壁1331，第一方向F1、第二方向F2与第三方向F3两两垂直。由此，泄压部12的设置可以避开同一电池排10多个电池单体1的相邻位置，从而避免在同一电池排10中相邻的两个电池单体1之间的位置进行泄压，有利于排气收集，降低热扩散的影响，而且可以提高结构紧凑性，减小对空间的占用。
在一些实施例中，例如图9所示，当泄压部12设于第一侧壁1331时，电连接部11相对第一侧壁1331靠近第二侧壁1332设置。也就是说，沿着第三方向F3，电连接部11与第一侧壁1331之间的距离大于电连接部11与第二侧壁1332之间的距离。由此，可以进一步拉远电连接部11与泄压部12之间的距离，降低泄压部12排出的排放物对电连接部11的影响，提高电池1000的使用安全性和可靠性。
在一些实施例中，如图9所示，当泄压部12设于第一侧壁1331时，泄压部12相对第一端壁131靠近第二端壁132设置。也就是说，沿着第二方向F2，泄压部12与第一端壁131之间的距离大于，泄压部12与第二端壁132之间的距离。由此，可以进一步拉远电连接部11与泄压部12之间的距离，降低泄压部12排出的排放物对电连接部11的影响，提高电池1000的使用安全性和可靠性。
在一些实施例中，如图3所示，电池单体1的厚度方向(例如图3中所示的第三方向F3)垂直于水平方向。可以理解的是，电池单体1的厚度小于电池单体1的长度，且电池 单体1的厚度小于电池单体1的宽度，电池单体1的长度大于等于电池单体1的宽度。其中，由于电池单体1的厚度方向垂直于水平方向，相当于电池单体1的厚度方向为竖直方向，此时，电池单体1相当于是平躺设置，占用的竖向空间较小，减小电池1000的整体高度，而且可以降低电池单体1的重心高度，缩小电池单体1的喷溅范围。
可以理解的是，电池单体1的重心高度越低，电池单体1通过泄压部12泄压时喷溅的高度也较低，从而可以减小电池单体1喷溅在上下方向上的影响范围，与此同时，电池单体1能够喷溅的距离也就越小，有利于提升安全性能。例如，电池单体1泄压时通过泄压部12排放排放物，由于电池单体1平躺设置，则可以降低泄压部12的高度，能够有效降低泄压部12喷发位置的高度，从而减小扩散区域、减小喷溅区域，提高电池1000整体的安全性能。
进一步地，在一些可选示例中，如图3所示，电池排10可以包括沿电池单体1的宽度方向(例如图3中所示的第一方向F1)排列的多个电池单体1，此时电池单体1的长度方向上的一侧壁面(例如第一端壁131)朝向同一电池组100中的另一电池排10。由此，当电池排10沿电池单体1的宽度方向的尺寸固定时，电池排10可以包括更多数量的电池单体1，从而提高电池1000的容量。
当然，本申请不限于此，例如在本申请的其他实施例中，电池排10还可以包括沿电池单体1的长度方向排列的多个电池单体1，此时电池单体1的宽度方向上的一侧表面朝向同一电池组100中的另一电池排10，这里不作赘述。
在一些实施例中，如图3所示，每个电池排10均包括沿第一方向F1排列的多个电池单体1，同组的两个电池排10沿第二方向F2排列，第二方向F2垂直于第一方向F1。由此，电池组100所包括的电池单体1的数量较多，电量较高。
进一步地，如图3所示，多个电池组100沿第三方向F3设置以构成多层电池组，第三方向F3垂直于第一方向F1和第二方向F2。由此，电池组100所包括的电池单体1的数量更多，电量更高。而且，通过设置“每个电池单体1的朝向同组另一电池排10的一侧设有电连接部11，每个电池单体1的泄压部12与电连接部11设于电池单体1的不同侧”，可以更好地保证多层电池组的安全可靠性，改善电池单体1在泄压过程中，对于其他电池组100的电连接部11的不利影响。
在一些实施例中，如图3所示，多层电池组中电池组100的数量小于电池排10中电池单体1的数量。由此，在保证电池排10布置一定数量的前提下，便于减小电池排10在高度方向上承受的挤压力，降低挤压力对电池单体1在泄压排放排放物时的剧烈程度造成的影响。
在一些实施例中，如图3所示，多层电池组中电池组100的数量为2～3。即多层电池组所包括的电池组100的数量为两个或三个。由此，在保证电池排10布置一定数量的前提下，便于减小电池排10在高度方向上承受的挤压力，降低挤压力对电池单体1在泄压排放排放物时的剧烈程度造成的影响。当然，本申请不限于此，例如在本申请的其他实施例中，多层电池组中电池组100的数量还可以为三个以上等等，这里不作赘述。
在一些实施例中，如图3和图6、图7所示，同组中对置的两个电池单体1构成一个对置单元20，至少一个对置单元20为第二对置单元22，第二对置单元22中的两个电池单体1的电连接部11正对设置，也就是说，沿着第二对置单元22中两个电池单体1的对置方向(例如图中所示的第二方向F2)作正投影，第二对置单元22中两个电池单体1的电连接部 11的正投影重合。由此，容易加工，例如可以实现电池单体1的同规格量产，从而降低成本。
在一些实施例中，如图10所示，第二对置单元22中，至少一对正对的电连接部11抵接支撑。由此，可以减小两者之间的间隙，提高结构紧凑性，提高空间利用率，并且可以提高电池1000的整体结构强度，提高电池1000的稳定性。需要说明的是，抵接支撑可以是直接或间接止抵，可以构成电连接，也可以是绝缘，当电连接时，可以是并联或串联，这里不作限制。
例如在一些可选示例中，电池单体1的朝向同组(同一电池组100)另一电池排10的一侧为第一端壁131，第二对置单元22中，每个电池单体1上的多个电连接部11凸出于第一端壁131的高度不同，两侧正对且凸出高度较大(相对较大)的电连接部11抵接支撑，其余两侧正对的(即凸出高度相对较小的)电连接部11间隙配合。由此，有利于实现同一电池组100的两个电池排10串联。
又例如在一些可选示例中，电池单体1的朝向同组(同一电池组100)另一电池排10的一侧为第一端壁131，第二对置单元22中，每个电池单体1上的多个电连接部11凸出于第一端壁131的高度相同，正对的电连接部11均抵接支撑。由此，有利于实现同一电池组100的两个电池排10并联。
简言之，并联时，两个电池排10正负极柱均相抵，串联时，采用高低极柱设置，高极柱相抵增强结构强度，低极柱尽量低，节省两个电池排10之间的空间。
在一些实施例中，如图11和图12所示，同组中对置的两个电池单体1构成一个对置单元20，至少一个对置单元20为第一对置单元21，第一对置单元21中的两个电池单体1的电连接部11错开设置，也就是说，沿着第一对置单元21中两个电池单体1的对置方向(例如图中所示的第二方向F2)作正投影，第一对置单元21中两个电池单体1的电连接部11的正投影不重合、错开。由此，通过将对侧的电连接部11设置为错开形式，可以使得同一电池组100中两个电池排10之间的距离减小，提高电池1000的空间利用率，提高电池1000的成组效率。
可以理解的是，当对侧的电连接部11错开设置时，相邻两个电池排10也可以通过多样化设计的电连接片实现电连接，这里不作赘述。
此外，可以理解的是，同一电池组100中的两个电池排10为“对侧的”两个电池排10，同一电池组100中一个电池排10上的电连接部11与另一个电池排10上的电连接部11为对侧的电连接部11；同一电池组100中一个电池排10上的泄压部12与另一个电池排10上的泄压部12为对侧的泄压部12；同一电池组100中一个电池排10上的第一端壁131与另一个电池排10上的第一端壁131为对侧的第一端壁131。
此外，电连接部11的错开方向不限。例如在一些实施例中，电池单体1的朝向同组另一电池排10的一侧为第一端壁131，第一对置单元21中，对侧的电连接部11沿第一端壁131的宽度方向错开，由此，可以使得电池单体1的长度尺寸可以减小。
再例如在一些实施例中，电池单体1的朝向同组另一电池排10的一侧为第一端壁131，第一对置单元21中，对侧的电连接部11沿第一端壁131的长度方向错开，由此，可以使得电池单体1的宽度尺寸可以减小。
又例如在一些实施例中，第一对置单元21中，对侧的电连接部11呈对角错开，例如第一对置单元21沿两个的排列方向(例如图中所示的第二方向F2)作正投影，其中一个电池 单体1的两个电连接部11分别位于左上角和右下角，另一个电池单体1的两个电连接部11分别位于左下角和右上角，从而可以充分利用空间，实现错开设置。
另外，使得对侧的电连接部11能够错开的方式可选。例如在一些可选方案中，电池单体1的朝向同组另一电池排10的一侧为第一端壁131，第一对置单元21中，各电连接部11相对第一端壁131的位置相同，且对侧的第一端壁131错开设置。由此，可以实现电池单体1的同规格加工，降低生产成本。
例如在另外一些可选方案中，电池单体1的朝向同组另一电池排10的一侧为第一端壁131，第一对置单元21中，各电连接部11相对第一端壁131的位置不同，且对侧的第一端壁131正对设置。由此，电池组100中的两个电池排10可以达到并排设置的效果，避免两个电池排10整体错开引发的空间浪费问题，可以提高结构紧凑性，节省空间。
在一些实施例中，如图12所示，电池单体1的朝向同组另一电池排10的一侧为第一端壁131，第一对置单元21中，对侧的第一端壁131之间的距离小于或等于对侧的电连接部11凸出于第一端壁131的高度之和。由此，可以进一步提高结构紧凑性，提高空间利用率。
在一些实施例中，如图13所示，同组中对置的两个电池单体1构成一个对置单元20，至少一个对置单元20中的两个电池单体1通过支撑结构30抵接支撑。由此，可以解决结构强度的问题，当对侧的电连接部11正对设置和错开设置时，均可以采用支撑结构30支撑，从而可以提高结构强度，提高电池1000的可靠性。
值得说明的是，当对侧的电连接部11正对设置且抵靠支撑时，电连接部11可以作为支撑结构30。
需要说明的是，当不采用电连接部11作为支撑结构30时，支撑结构30可以仅设置在其中一个电池单体1上，也可以正对且分设在对侧的两个电池单体1上。
例如在一些实施例中，如图13所示，电池单体1的朝向同组另一电池排10的一侧为第一端壁131，支撑结构30包括设于第一端壁131的支撑台31，即设置在同一第一端壁131上的支撑台31与电连接部11是间隔设置的，由此，可以通过支撑台31实现支撑，提高结构强度。而且容易实现两个电池排10之间所需绝缘位置的绝缘要求。
可选地，支撑台31可以位于边缘且零散设置，而非环绕第一端壁131整周的环形结构，从而可以留出空间，方便进行电连接和走线。
可选地，如图13所示，通过支撑结构30抵接支撑的两个电池单体1中每个均设有支撑台31，对侧的支撑台31相对以抵接支撑。由此，电池单体1可以实现统一规格加工，有利于提高生产效率。
或者可选地，通过支撑结构30抵接支撑的两个电池单体1中只有一个设有支撑台31，该支撑台31支撑于对侧的电池单体1的第一端壁131。由此，可以降低装配难度，避免对侧的支撑台31错位导致的支撑不稳等问题。
需要说明的是，支撑台31的加工方式不限，例如在一些实施例中，支撑台31可以一体成型于第一端壁131。由此，可以减少安装时的工序，便于成组。又例如在一些实施例中，支撑台31与第一端壁131可以为分体结构，且支撑台31装配至第一端壁131，从而使得支撑台31可以单独制造，便于成型。
在一些实施例中，支撑结构30可以包括设于对侧的电池单体1之间的填充胶。即通过胶体也可以实现对侧的两个电池单体1的固定支撑，增强结构强度，从而简化电池单体1的加工。值得说明的是，支撑结构30还可以同时包括支撑台31和填充胶等，从而进一步 提高结构强度。
在一些实施例中，电池组100中的两个电池排10之间设有绝缘件40。由此，可以起到绝缘隔离两个电池排10的电连接部11的作用，避免两个电池排10的电连接部11之间由于爬电距离过小出现高压打火问题。而且，热失控时，可以有效避免某个泄压部12排放的排放物在两个电池排10之间导通，引发高压打火问题，从而提高电池1000的安全性与可靠性。
例如在一些可选示例中，如图14所示，绝缘件40可以包括设于两个电池排10之间的绝缘片和绝缘胶，绝缘片通过绝缘胶固定于电池排10，绝缘胶为填充胶或双面胶。由此，可以起到有效的绝缘效果，具有高压防护作用，并且可以提高电池组100的整体结构强度。其中，绝缘片的材质不限，例如可以为云母片等，还可以具有耐高温的防火效果。
例如在另外一些可选示例中，如图15所示，电池组100中的至少一个电池排10上设有绝缘罩41，绝缘罩41罩设相应电池排10(即绝缘罩41所设置的电池排10)上的电连接部11。由此，绝缘罩41的固定方式方便，可以起到较为有效的防高压打火作用。值得说明的是，可以在其中一个电池排10上设置绝缘罩41，也可以在两个电池排10上分别设置绝缘罩41，这里不作赘述。
在本申请的一些实施例中，每个电池排10均包括多个电池单体1，同组(同一电池组100)对侧的电连接部11之间不连接。也就是说，单侧的电池排10内电连接，然后一体对外输出。由此，可以简化电连接。
在本申请的另外一些实施例中，如图16所示，每个电池排10均包括沿第一方向F1排列的多个电池单体1，同组的两个电池排10沿第二方向F2排列，多个电池组100沿第三方向F3设置以构成多层电池组，例如第一方向F1、第二方向F2和第三方向F3两两相互垂直。结合图17，多层电池组中位于同侧的电池排10(即电连接部11朝向相同且相邻的两个电池排10)之间电连接。也就是说，同侧的相邻电池排10之间内电连接，一体对外输出。由此，可以简化电连接。
在本申请的另外一些实施例中，每个电池排10均包括多个电池单体1，同组对侧的电连接部11之间电连接。例如，同组两侧对置的电连接部11直接对焊，由此可以提高结构紧凑性，优化空间利用率。或者，同组对侧的电连接部11通过导电片80连接，即相对两排电池排10用汇流片实现电连接，从而可以降低工艺难度。
在本申请的一些实施例中，如图18所示，电池1000还包括：热管理部件50，热管理部件50包括换热部501且用于与电池单体1换热。例如换热部501与电池单体1换热以带走电池单体1的热量，或者换热部501用于向电池单体1传递热量以实现电池单体1的预热等，便于使得电池单体1具有合适的工作温度，以保证电池单体1的使用寿命。
例如在一些实施例中，如图18-图20所示，热管理部件50可以包括第一梁51，第一梁51设于同组(同一电池组100)两个电池排10之间，且第一梁51的朝向每个电池排10的一侧均具有换热部501。由此，换热部501朝向电连接部11设置，可以用于对电连接部11调节温度，例如可以用于冷却过电流部件，如极柱、汇流片等，从而提高电池1000的工作安全性和可靠性。
例如在一些实施例中，如图21-图22所示，热管理部件50还可以包括第二梁52，第二梁52设于同组(同一电池组100)两个电池排10的相背侧，且第二梁52的朝向相应电池排10的一侧均具有换热部501。也就是说，每个电池排10的远离另一电池排10的一 侧设有第二梁52，第二梁52的朝向电池排10的一侧设有电连接部11，从而对电池排10调节温度。由此，通过将第二梁52远离电连接部11设置，当第二梁52内设有调温液体流路时，在第二梁52发生意外产生漏液时，可以避免漏液对电连接部11造成的短路问题。
在一些实施例中，如图23所示，电池1000还包括箱体部件60，箱体部件60包括侧围板61和分隔梁62，分隔梁62位于侧围板61围绕出的空间内，以将空间划分为多个容置腔，容置腔用于容纳电池排10，分隔梁62构造为热管理部件50。由此，利用分隔梁62作为热管理部件50调节电池单体1的温度，可以节省对空间的占用，提高空间利用率。
在一些实施例中，如图24所示，电池1000还包括排放部件70，排放部件70内形成有排放腔701，排放部件70设于泄压部12朝向的一侧，排放腔701用于接收泄压部12排出的排放物。也就是说，将排放部件70设置在电池单体1的设有泄压部12的一侧，从而有利于收集排放物，避免排放物无序扩散造成的不良影响，降低热失控的扩散影响，提高电池1000的安全性。
可选地，排放部件70的朝向电池排10的一侧还具有换热部501。由此，排放部件70也可以作为热管理部件50，例如上文所述的第二梁52，这样可以使二者合二为一，具有换热和收集排放物双重功能，从而节省对空间的占用，提高空间利用率。
根据本申请第二方面实施例的用电装置2000，包括根据本申请上述第一方面实施例的电池1000，电池1000用于为用电装置2000提供电能。由此，通过采用上述的电池1000，有利于提升用电装置2000的使用安全性和可靠性。
可选地，如图25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。
需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互结合。
以上仅为本申请的优选实施例而已，并不用于限制本申请，对于本领域的技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的保护范围之内。
