电池100还可以包括其他结构，例如，该电池100还可以包括汇流部件，用于实现多个电池单体201之间的电连接。
其中，每个电池单体201可以为二次电池或一次电池；还可以是锂硫电池、钠离子电池或镁离子电池，但不局限于此。电池单体201可呈圆柱体、扁平体、长方体或其它形状等。
本申请的一些实施例提供一种电池模块20的端板1，如图4所示，该端板1设有沿第一方向X相对设置的第一端面11和第二端面12，第一端面11被配置为背离电池100的电池单体201，第二端面12被配置为面向电池单体201；端板1设置有于第一端面11凹陷的凹槽13，凹槽13包括连通的第一槽体131和第二槽体132，第二槽体132位于第一槽体131沿第二方向Y的一侧，第二槽体132沿第三方向Z的尺寸大于第一槽体131沿第三方向Z的尺寸，第一方向X、第二方向Y以及第三方向Z两两垂直。

凹槽13可以是设置于端板1上的槽状结构，其可以用于装入吊钩等吊具，使得吊钩等吊具能够通过起吊端板1对电池模块20进行起吊。凹槽13通过在第一端面11凹陷形成，使得外部的吊钩等吊具能够从端板1背离电池单体201的一侧(电池模块20的外侧)进入凹槽13，以使吊钩等吊具与端板1连接。示例性地，凹槽13可以随端板1采用铸造等一体成型的加工方法制成，使得端板1能够进行整体同步制造，不仅使得端板1的加工制造方便，还使得端板1的整体结构具有良好的强度；凹槽13还可以采用铣削等机械加工的方法，通过对端板1进行加工制成，使得该端板1具有较低的加工难度和加工成本。
第一槽体131和第二槽体132分别是凹槽13的部分结构，两者相互连通共同形成凹槽13。其中，第二槽体132设置于第一槽体131沿第二方向Y的一侧，使得吊钩等吊具能够从第一槽体131中沿第二方向Y移动进入第二槽体132，使得吊钩等吊具能够方便地连接于端板1。
第二槽体132沿第三方向Z的尺寸大于第一槽体131沿第三方向Z的尺寸可以是，第二槽体132在第三方向Z上的长度大于第一槽体131在第三方向Z上的长度，这使得凹槽13整体呈L形，使得吊钩等吊具从第一槽体131移动进入第二槽体132中后，能够被壁面限制于第二槽体132凸出于第一槽体131的部分，使得吊钩等吊具能够吊运端板1及其所在的电池模块20。
其中，第一方向X、第二方向Y以及第三方向Z设置为两两垂直，便于该端板1中的结构进行设置。
在上述结构中，凹槽13中的第二槽体132位于第一槽体131沿第二方向Y的一侧且第二槽体132沿第三方向Z的尺寸大于第一槽体131沿第三方向Z的尺寸，使得凹槽13呈L形，外部的吊钩等吊具能够经由第一槽体131进入第二槽体132对该端板1起吊，还能够经由第一槽体131脱开与端板1的接触，减小了吊具对端板1外的空间的占用，从而减小电池100组装时占用的空间，使得电池100组装更加便利，有利于提高电池100的生产效率。
在一些实施例中，第一槽体131延伸至端板1沿第二方向Y的边缘 并形成开口。
通过将第一槽体131延伸至端板1沿第二方向Y的边缘，使得第一槽体131沿第二方向Y通过开口与端板1外部连通，使得吊钩等吊具能够通过沿第二方向Y移动从外部进入凹槽13，使得吊钩等吊具与该端板1的连接方便。
在一些实施例中，开口可以设有倒角，倒角具有导向作用，使得吊钩等吊具能够方便地从开口进入凹槽13。
在一些实施例中，在第二方向Y上，第二槽体132与端板1的边缘间隔设置，第二槽体132与端板1的边缘之间形成限位结构。
限位结构可以为端板1上设置的结构，其用于对吊钩等吊具进行限位。第二槽体132在第二方向Y上与端板1的边缘间隔设置，第二槽体132与端板1的边缘之间形成限位结构，限位结构能够对进入第二槽体132中的吊钩等吊具进行限位，减小第二槽体132中的吊钩等吊具在第二方向Y上的移动，提高吊钩等吊具与端板1连接的稳定性。
在一些实施例中，第二槽体132的槽面包括第一底面1321和两个第一侧面1322，第一底面1321沿第二方向Y面向第一槽体131，两个第一侧面1322沿第三方向Z间隔设置并连接于第一底面1321的两端。

在一些实施例中，第一槽体131沿第三方向Z的一端设置有第二侧面1311，第一侧面1322和第二侧面1311共面。
第二侧面1311可以是第一槽体131中设置在第三方向Z的一端的内壁面。通过将第二侧面1311与第一侧面1322共面设置，使得第一槽体131和第二槽体132在第三方向Z的一端的内壁面共面，从而使第一槽体131连通于第二槽体132在第三方向Z的一端，使得第一槽体131和第二 槽体132形成的凹槽13呈L形。
在一些实施例中，端板1设有第一定位孔14，第一定位孔14与凹槽13连通。
第一定位孔14可以是端板1上设置的孔状结构，其用于将吊钩等吊具与端板1进行定位。第一定位孔14可以用于穿设定位销、连接螺栓等连接件，通过将第一定位孔14与凹槽13连通，使得穿过第一定位孔14的连接件能够与位于凹槽13中的吊具连接，实现吊具与端板1的相对定位，有利于提高吊具吊运端板1时的稳定性。
在一些实施例中，第一定位孔14连通于第二槽体132并沿第三方向Z延伸。
通过使第一定位孔14连通于第二槽体132并沿第三方向Z延伸，使得端板1之外的连接件能够通过第一定位孔14沿第三方向Z插入第二槽体132中，使得连接件能够方便地与位于第二槽体132中的吊具连接。
在一些实施例中，端板1设有第二定位孔15，第二定位孔15设置于凹槽13的内壁上并与第一定位孔14对应。
第二定位孔15可以是端板1上设置的孔状结构，其用于将吊钩等吊具与端板1进行定位。第二定位孔15可以用于穿设定位销、连接螺栓等连接件，通过将第二定位孔15设置于凹槽13的内壁上并与第一定位孔14正对，使得连接件能够穿过第一定位孔14连接于吊具后，还能穿设于第二定位孔15，有利于提高吊具与端板1的连接稳定性。
在一些实施例中，第二定位孔15为盲孔。
通过将第二定位孔15设置为盲孔，能够减小第二定位孔15的加工量，有利于简化第二定位孔15的加工。示例性地，第一定位孔14可以为光孔，连接件可以为连接螺栓，第二定位孔15可以为螺纹孔，连接件可以依次穿过第一定位孔14、吊具后连接于第二定位孔15。
示例性地，第一定位孔14和第二定位孔15可以采用钻孔等机械加工的方法，通过对端板1进行加工制成，使得该端板1具有较低的加工难度和加工成本。
在一些实施例中，第一定位孔14和第二定位孔15分别位于两个第 一侧面1322。
通过将第一定位孔14和第二定位孔15分别设置于两个第一侧面1322上，使得第一定位孔14和第二定位孔15分别连通于第二槽体132的两端，使得位于第二槽体132中的吊具能够被与第一定位孔14和第二定位孔15连接的连接件连接。
本申请的一些实施例还提供一种电池模块20，该电池模块20包括多个电池单体201和两个上述技术方案所提供的电池模块20的端板1，两个端板1沿第一方向X间隔设置，多个电池单体201堆叠于两个端板1之间。
在一些实施例中，两个端板1可以通过钢带等连接件连接起来。通过将多个电池单体201堆叠于两个沿第一方向X间隔设置的端板1之间，使得两个端板1能够将多个电池单体201夹紧以控制电池单体201的膨胀。
由于该电池模块20包括上述技术方案所提供的端板1，外部的吊钩等吊具在吊起该电池模块20时，对端板1外的空间占用较小，减小了电池100组装时占用的空间，使得电池100组装更加便利，有利于提高电池100的生产效率。
本申请的一些实施例还提供一种电池100，该电池100包括箱体10和上述技术方案所提供的电池模块20，电池模块20设置于箱体10的容纳空间中。

下面对吊具与端板1的连接及脱离进行说明。
吊具沿第三方向Z移动至第二槽体132所在的平面后，吊具可通过旋转从第一槽体131的开口进入凹槽13，然后吊具沿第二方向Y向第二槽体132移动，待吊具进入第二槽体132后，吊具沿第三方向Z移动进入第二槽体132相对于第一槽体131凸出的部分，连接件依次穿过第一定位孔14、吊具后连接于第二定位孔15，吊具即可起吊端板1；待吊运结束后，将连接件从第二定位孔15、吊具和第一定位孔14中抽出，吊具沿第三方向Z移动进入第一槽体131，吊具可通过旋转从第一槽体131中脱离凹槽13。由上述方案可知，该端板1能够减小电池100组装时对外界占用的空间，吊使得电池100组装更加便利，有利于提高电池100的生产效率。
