 本发明的实施方式
参阅图1至图3，本申请提供了一种电池100，电池100包括电池主体110、正极柱120和负极柱130，其中，正极柱120设置在电池主体110的一端面111上，正极柱120凸出于电池主体110的端面111，负极柱130设置在电池主体110的一端面111上，负极柱130凸出于电池主体110的端面111，负极柱130与正极柱120位于同一端面上，负极柱130与正极柱120之间具有间隙，负极柱130与正极柱120分别位于电池主体110的轴截面的两侧，正极柱120的顶面到电池主体110的端面111的高度高于或低于负极柱130的顶面到电池主体110的端面111的高度。
具体的，正极柱120的顶面到电池主体110的端面111的高度与负极柱130的顶面到电池主体110的端面111的高度不同。其中，正极柱120的顶面到电池主体110的端面111的高度高于负极柱130的顶面到电池主体110的端面111的高度，或者，负极柱130的顶面到电池主体110的端面111的高度高于正极柱120的顶面到电池主体110的端面111的高度。
本申请中，通过将正极柱120和负极柱130设置在电池主体110的同一端面111上，且正极柱120和负极柱130之间具有间隙，能够保证正极柱120和负极柱130均设置在电池主体110的同一端的同时，相互隔开且不会产生接触，防止正极柱120和负极柱130连通而引发短路，使汇流排可以集成在电池的同一端，提高动力电池的生产效率，降低生产的时间成本和人力成本，并且，通过将正极柱120和负极柱130设置在电池主体110的轴截面的两侧，正极柱120和负极柱130的高度不同，以便操作者快速区分正极柱120和负极柱130，使操作者在连接电池100时，不需要花费过多注意力和操作即可完成电池100的连接操作，从而起到防呆效果，避免生产时出现连接错误的情况，降低了串并联相邻两个电池100的难度。
本实施例中，正极柱120在电池主体110的端面111上的正投影与负极柱130在电池主体110的端面111上的正投影关于电池主体110的端面的中线对称，能够保证电池主体110的正极柱120和负极柱130的过流面积相同。
