电池单体包括电极组件和电解液，电极组件由正极片、负极片和隔离膜组成。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。隔膜的材质可以为聚丙烯(Polypropylene，PP)或聚乙烯(Polyethylene，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。
为了满足不同的电力需求，电池中的多个电池单体之间可以串联、并联或混联，其中混联是指串联和并联的混合。可选地，多个电池单体可以先串联、并联或混联组成电池模块，多个电池模块再串联、并联或混联组成电池。也就是说，多个电池单体可以直接组成电池，也可以先组成电池模块，电池模块再组成电池。电池再进一步设置于用电设备中，为用电设备提供电能。
电池技术的发展要同时考虑多方面的设计因素，不仅要考虑能量密度、循环寿命、放电容量、充放电倍率等性能参数，还要考虑电池的组装技术。电池的组装过程较为复杂，需要耗费大量的时间和人力，因此，需要简化电池的组装工序，提高电池的组装效率。
电池通常包括多个电池单体，在电池的内部往往通过汇流部件实现多个电池单体之间的电连接，例如并联或串联或混联。具体地，汇流部件可通过连接电池单体的电极端子实现电池单体之间的电连接。然而，通过汇流部件连接的电池单体往往会形成悬挂式的结构，汇流部件也容易因为外力受到损坏，例如，受到冲击而断裂。因此通常会在多个电池单体形成的电池模组之间增加横梁或隔板，以加强电池单体之间的强度。但这种方式不可避免地会增加电池的组装工序，提高电池组装的难度，降低电池的组装效率。
鉴于此，本申请提供了一种电池单体，电池单体的第一连接器的第一引脚与电极组件的极耳相连，外部连接器与第一连接器插接后能够实现电池单体间的电连接。也就是说，本申请中的电池单体通过第一连接器与外部连接器插接即可实现电池单体间的电连接。传统的实现电池单体间的电连接方式通常是在电池单体上设置电极端子，电极端子需要与汇流部件焊接或者是通过转接片与汇流部件连接来实现电池单体间的电连接，该过程增加了电池组装的难度，耗费了电池组装的时间。而在本申请中，电池单体通过第一连接器与外部连接器插接即可实现电池单体间的电连接，不需要在电池单体上设置电极端子，也不需要设置汇流部件与电极端子连接，提高了组装效率，也节省了汇流部件占据的空间，提高了电池内部空间的利用率。另外，电池单体的外壳在第一方向的端部具有台阶结构，将第一连接器设置于该台阶结构上，台阶结构为第一连接器提供了空间，使得该第一连接器不需要占用电池内部额外的空间，从而能够保证电池内部空间的合理利用，提高电池内部空间的利用率。
本申请实施例描述的技术方案均适用于各种使用电池的用电设备。用电设 备可以是车辆、手机、便携式设备、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；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、电动汽车玩具、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。本申请实施例对上述用电设备不做特殊限制。
以下实施例为了方便说明，以用电设备为车辆为例进行说明。
例如，如图1所示，为本申请一个实施例的一种车辆1的结构示意图，车辆1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1的内部可以设置马达40，控制器30以及电池10，控制器30用来控制电池10为马达40的供电。例如，在车辆1的底部或车头或车尾可以设置电池10。电池10可以用于车辆1的供电，例如，电池10可以作为车辆1的操作电源，用于车辆1的电路系统，例如，用于车辆1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10不仅仅可以作为车辆1的操作电源，还可以作为车辆1的驱动电源，替代或部分地替代燃油或天然气为车辆1提供驱动动力。
电池10可以包括多个电池单体。例如，如图2所示，为本申请一个实施例的一种电池10的结构示意图，电池10可以包括至少一个电池模块200。电池模块200包括多个电池单体20。电池10还可以包括箱体11，箱体11内部为中空结构，多个电池单体20容纳于箱体11内。如图2所示，箱体11可以包括两部分，这里分别称为第一部分111(上箱体)和第二部分112(下箱体)，第一部分111和第二部分112扣合在一起。第一部分111和第二部分112的形状可以根据多个电池单体20组合的形状而定，第一部分111和第二部分112可以中至少一个具有一个开口。例如，如图2所示，第一部分111和第二部分112均可以为中空长方体且各自只有一个面为开口面，第一部分111的开口和第二部分112的开口相对设置，并且第一部分111和第二部分112相互扣合形成具有封闭腔室的箱体11。再例如，不同于图2所示，第一部分111和第二部分112中可以仅有一个为具有开口的中空长方体，而另一个为板状，以盖合开口。例如，这里以第二部分112为中空长方体且只有一个面为开口面，第一部分111为板状为例， 那么第一部分111盖合在第二部分112的开口处以形成具有封闭腔室的箱体，该腔室可以用于容纳多个电池单体20。多个电池单体20相互并联、串联或混联组合后，置于第一部分111和第二部分112扣合后形成的箱体11内。
根据不同的电力需求，电池单体20的数量可以设置为任意数值。多个电池单体20可通过串联、并联或混联的方式连接以实现较大的容量或功率。由于每个电池10中包括的电池单体20的数量可能较多，为了便于安装，可以将电池单体20分组设置，每组电池单体20组成电池模块。电池模块中包括的电池单体20的数量不限，可以根据需求设置。电池可以包括多个电池模块，这些电池模块可通过串联、并联或混联的方式进行连接。
下面结合图3和图4详细说明本申请实施例提供的电池单体20。
如图3所示，是本申请实施例提供的一种电池单体20的结构示意图，该电池单体20包括外壳21、电极组件和第一连接器31，外壳21在第一方向x上的端部具有台阶结构211，电极组件设置于外壳21内，该电极组件包括极耳，第一连接器31设置在台阶结构211处，第一连接器31包括第一引脚311，该第一引脚311与电极组件的极耳连接，第一连接器31被配置为能与外部连接器32插接以实现电池单体20间的电连接。
该外壳21的台阶结构211可以通过多种加工工艺得到，例如，冲压、机加工等，外壳21与台阶结构211也可以一体成型，本申请对此不做限定。
电极组件是电池单体20中发生电化学反应的部件。电极组件可以是圆柱体、长方体等，若电极组件为圆柱体结构，外壳21也可以为圆柱体结构，若电极组件为长方体结构，外壳21也可以为长方体结构。
第一连接器31是指具有传输信号、接通电流功能的电子器件，例如，可以是BTB/FPC连接器、Type-C连接器、USB连接器等，本申请对此不做限定。
由于电池单体20的第一连接器31的第一引脚311与电极组件的极耳相连，外部连接器32与第一连接器31插接后能够实现电池单体20间的电连接。也就是说，本申请中的电池单体20通过第一连接器31与外部连接器32插接即可实现电池单体20间的电连接。传统的实现电池单体20间的电连接方式通常是在电池单体20上设置电极端子，电极端子需要与汇流部件焊接或者是通过转接片与汇流部件连接来实现电池单体20间的电连接，该过程增加了电池10组装的难度，耗费了电池10组装的时间。而 在本申请中，电池单体20通过第一连接器31与外部连接器32插接即可实现电池单体20间的电连接，不需要在电池单体20上设置电极端子，也不需要设置汇流部件与电极端子连接，简化了电池20的组装工序，提高了组装效率，也节省了汇流部件占据的空间，提高了电池10内部空间的利用率。另外，电池单体20的外壳21在第一方向x的端部具有台阶结构211，将第一连接器31设置于该台阶结构211上，台阶结构211为第一连接器31提供了空间，使得该第一连接器31不需要占用电池10内部额外的空间，从而能够保证电池10内部空间的合理利用，提高电池10内部空间的利用率。

台阶结构211设置有垂直于第一方向x的第一台阶面2111和垂直于第二方向y的第二台阶面2112，这样，第一台阶面2111和第二台阶面2112形成的“L”型结构在电池单体20的外壳21上形成方形空间，使第一连接器31设置于台阶结构211时，可以置于该方形空间中，无需占用电池10中的其他区域。第一连接器31可以设置于第一台阶面2111，也可以设置于第二台阶面2112，当第一连接器31设置于第一台阶面2111时，其第一引脚311平行于第二台阶面2112，外部连接器32沿第一方向x与其插接；当第一连接器31设置于第二台阶面2112时，其第一引脚311平行于第一台阶面2111，外部连接器32沿第二方向y与其插接。

设置第一连接器31在第三方向z上的长度L1不大于外壳21在第三方向z的长度L2，从而保证在第三方向z上第一连接器31占用的空间完全为台阶结构211占用的空间，不会占用电池10内部其他区域的空间。
