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。
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PP或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。
为了提高电池的容量，通常是将串联的多个电池单体装入具有一定强度的外壳内形成电池。在电池使用过程中，电池单体之间的连接处会晃动，存在撕裂风险。
有鉴于此，本申请实施例提供了一种电池，在两个串联的电池单体之间设置支架，并使两个电池单体的连接部设置在支架的容纳空间内，可以较好地固定电池单体的连接处，防止连接处的晃动，从而可以降低撕裂风险，提高电池的电连接稳定性。
本申请实施例描述的技术方案均适用于各种使用电池的装置，例如，手机、便携式设备、笔记本电脑、电瓶车、电动玩具、电动工具、电动车辆、船舶和航天器等，例如，航天器包括飞机、火箭、航天飞机和宇宙飞船等。
应理解，本申请实施例描述的技术方案不仅仅局限适用于上述所描述的用电装置，还可以适用于所有使用电池的设备，但为描述简洁，下述实施例均以电动车辆为例进行说明。
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80，控制器60以及电池100，控制器60用来控制电池100为马达80的供电。例如，在车辆1的底部或车头或车尾可以设置电池100。电池100可以用于车辆1的供电，例如，电池100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100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。
图2示出了本申请实施例的电池100的一种示意立体图。如图2所示，电池100包括电池模组110，电池模组110包括沿第一方向X串联设置的第一电池单体111和第二电池单体112，第一电池单体111的第一电极输出部111a和第二电池单体的第二电极输出部112a通过焊接的方式电连接，第一方向X为电池100的长度方向；电池100还包括支架120，支架120设置在第一电池单体111和第二电池单体112之间，支架120设置有第一容纳空间121，第一容纳空间121在第一方向X上贯通支架120，第一容纳空间121用于容纳第一电极输出部111a和第二电极输出部112a。
为了便于描述，此处先对各个方向进行定义。如图2所示，第一方向X为电池100的长度方向，第二方向Y为电池100的宽度方向，第三方向Z为电池100的厚度方向。
本申请中的电极输出部可以是指上文中所描述的极耳穿出电池单体外包装的部分，也可以理解成在电池单体的外包装的外部与极耳电连接的电连接片，本申请实施例对此不作限定。
本申请实施例中的电池模组110可以包括多个电池单体，多个电池单体串联连接，即一个电池单体的正极输出部与相邻的另一个电池单体的负极输出部连接。多个电池单体可以如图2所示，沿第一方向X呈一排设置。可选地，多个电池单体也可以沿第一方向X呈多排设置。
本申请实施例中的第一电池单体111的第一电极输出部111a和第二电池单体112的第二电极输出部112a通过焊接的方式电连接，可以包括第一电极输出部111a和第二电极输出部112a采用超声波焊接电连接或者激光焊接电连接。可选地，第一电极输出部111a和第二电极输出部112a可以直接焊接或者通过一个连接件间接焊接。由于第一电池单体111的第一电极输出部111a和第二电池单体112的第二电极输出部112a在装配支架120之前已经焊接，故支架120必须设置有在第一方向上贯穿支架120的第一容纳空间121，才能使得连接后的第一电极输出部111a和第二电极输出部112a沿第二方向Y穿入第一容纳空间内121，并由第一容纳空间121容纳第一电极输出部111a和第二电极输出部112a。
因此，在实施例中，在串联的第一电池单体111和第二电池单体112之间设置支架120，并使第一电池单体111和第二电池单体112的连接部设置在支架120的第一容纳空间121内，可以较好地固定电池单体的连接处，防止连接处的晃动，从而可以降低连接处撕裂的风险，提高电池100的电连接稳定性；另外，支架120的存在能够增加电池模组110的整 体刚度，从而方便电池模组110入壳装配。
虽然本申请实施例是以第一电池单体111和第二电池单体112的连接为例描述的，但当一排设置有两个以上电池单体时，本申请的电池100可以包括多个支架，每个支架的结构和功能均可参见第一电池单体111和第二电池单体112之间的支架120，为了简洁，本文不过多描述其他电池单体之间的支架。
图3示出了本申请实施例的电池100的另一种示意立体图。如图3所示，电池100包括电池模组110，电池模组110包括沿第一方向X串联设置的第一电池单体111和第二电池单体112，电池模组110还包括沿第一方向X串联设置的第三电池单体113和第四电池单体114，其中，第一电池单体111和第三电池单体113沿第三方向堆叠设置，第二电池单体112和第四电池单体114沿第三方向堆叠设置。第一电池单体111的第一电极输出部111a和第二电池单体112的第二电极输出部112a通过焊接的方式电连接，第三电池单体113的第三电极输出部113a和第四电池单体114的第四电极输出部114a通过焊接的方式电连接。电池100还包括支架120，支架120设置有第一容纳空间121和第二容纳空间122，且第一容纳空间121和第二容纳空间122沿第三方向Z间隔设置，第一容纳空间121用于容纳第一电极输出部111a和第二电极输出部112a，第二容纳空间122用于容纳第三电极输出部113a和第四电极输出部114a。
在实施例中，采用一个支架120固定沿两排设置的两对相邻电池单体的连接部，能够加强相邻两排电池单体的整体强度，并且能够提高电池100的能量密度。
可选地，第一容纳空间121在第一方向X上贯通支架120，第二容纳空间122也在第一方向X上贯通支架120。
需要说明的是，当本申请中的电池模组110包括的多个电池单体沿 第一方向X呈两排以上设置时，支架120可以沿第三方向Z间隔设置两个以上容纳空间，每个容纳空间容纳对应的两个电池单体的连接部，本申请实施例对此不作限定。
图4示出了本申请实施例的电池100的装配示意图。如图4所示，需要先将位于同一排的相邻两个电池单体的电极输出部焊接，例如，将第一电池单体111的第一电极输出部111a和第二电池单体112的第二电极输出部112a在焊接点115处焊接。其中，第一电极输出部111a和第二电极输出部112a中的一个为负极输出部，另一个为正极输出部。进一步地，可以在两个相邻电池单体之间沿第二方向Y插入支架120。例如，将第一电池单体111的第一电极输出部111a和第二电池单体112的第二电极输出部112a的焊接位置插入支架120的第一容纳空间121，直至支架120在第二方向Y上横跨整个电池单体为止。

在实施例中，采用结构胶将各个电池单体与所述支架120固定连接，可以加强电池模组110与支架120之间的刚度，防止电池模组110与支架120的相对位移，降低对电池单体的损伤。
可选地，继续参见图7，支架本体123的用于支撑第一电极输出部111a和第二电极输出部112a的壁上设置有沿第二方向Y延伸的第一容纳槽1233，第一容纳槽1233容纳有第一采样端子，第一采样端子用于采集第一电池单体111和/或第二电池单体112的参数。
第一采样端子可以是温度传感器，例如，负温度系数(Negative Temperature Coefficient，NTC)温度传感器。第一采样端子还可以是电压传感器、电流检测器等，本申请实施例对第一采样端子的类型不作限定。
在实施例中，通过在支架本体123的用于支撑第一电极输出部111a和第二电极输出部112a的壁上设置第一容纳槽1233以容纳第一采样端子，可以实现对第一电池单体111和/或第二电池单体112的实时监测，从而可以提高电池100的安全性。
进一步地，第一容纳槽1233还容纳有结构胶，第一采样端子和所述支架120通过结构胶固定连接。
在实施例中，将第一采样端子和支架120通过结构胶固定连接，可以避免第一采样端子的晃动，从而可以提高第一采样端子的采样准确性。
类似地，继续参见图7，支架本体123的用于支撑第三电极输出部113a和第四电极输出部114a的壁上设置有沿第二方向延伸的第二容纳槽1234，第二容纳槽1234容纳有第二采样端子，第二采样端子用于采集第三电池单体113和/或第四电池单体114的参数。
第二采样端子可以是温度传感器，例如，NTC温度传感器。第二采样端子还可以是电压传感器、电流检测器等，本申请实施例对第二采样端子的类型不作限定。
在实施例中，通过在支架本体123的用于支撑第三电极输出部113a和第四电极输出部114a的壁上设置第二容纳槽1234以容纳第二采样端子，可以实现对第三电池单体113和/或第四电池单体114的实时监测，从而可以提高电池100的安全性。
进一步地，第二容纳槽1234还容纳有结构胶，第二采样端子和所述支架120通过结构胶固定连接。
在实施例中，将第二采样端子和支架120通过结构胶固定连接，可以避免第二采样端子的晃动，从而可以提高第二采样端子的采样准确性。
可选地，在本申请实施例中，在第三方向Z上，第二固定件125和第一固定件124相对于支架本体123对称设置。对称设置可以是指第二固定件125和第一固定件124的结构完全一致且位置对称，也可以仅仅指第二固定件125和第一固定件124的位置对称而结构不完全一致。
在实施例中，第二固定件125和第一固定件124相对于支架本体123对称设置，可以降低支架120的生产难度。
图9为图3所示的电池100的主视图。图10为图3所示的电池100的俯视图。可选地，如图9所示，在第三方向Z上，支架120的尺寸 为H1，电池模组110的尺寸为H2，其中，H1大于H2。应理解，H2可以是电池模组110在第三方向Z上的最大尺寸。可选地，如图10所示，在第二方向Y上，支架120的尺寸为W1，电池模组110的尺寸为W2，其中，W1大于W2。
在实施例中，在第三方向Z上，将支架120的尺寸H1设置成大于电池模组110的尺寸H2，以及在第二方向Y上，将支架120的尺寸W1设置成大于电池模组110的尺寸W2，可以在电池100受到震动冲击时，支架120先与壳体接触，起到缓冲作用，降低电池单体的损坏。
图11示出了本申请实施例的电池100的示意性爆炸图。如图11所示，电池100还包括壳体130，壳体130用于容纳电池模组110和支架120。
在一种实施例中，壳体130可以是金属壳，例如，壳体130可以是铝壳。在此情况下，支架120为绝缘支架，以避免电池模组110中电池单体之间的电极输出部与壳体130接触，提高电池100的安全性。例如，支架120为塑胶支架。
在另一种实施例中，壳体可以是绝缘壳，例如，壳体130为塑胶壳体。此时，支架120可以是任意材质的支架。
在实施例中，将电池模组110和支架120设置在壳体130内，可以降低在电池100受到震动冲击时电池单体被损坏的风险。
可选地，壳体130设置有开口，电池100还包括：端盖，端盖盖合开口，以将电池模组110和支架120封装在壳体130内。需要说明的是，本申请实施例对开口的数量和位置不作限定。例如，壳体130可以设置一个开口，开口可以设置在任何一个方向上，对应地，电池100包括一个端盖。再例如，壳体130可以设置两个开口，两个开口可以沿任何一个方向相对设置，对应地，电池100包括两个端盖。
进一步地，端盖还设置有正电极端子和负电极端子，正电极端子与所述电池模组110的正极输出部电连接，所述负电极端子与所述电池模组110的负极输出部电连接。
如图11所示，壳体130沿第一方向X设置有第一开口131和第二开口132，电池100还包括：第一端盖141和第二端盖142，第一端盖141和第二端盖142可以分别盖合壳体130的第一开口131和第二开口132，以将电池模组110和支架120封装在壳体130内。例如，第一端盖141盖合第一开口131，第二端盖142盖合第二开口132。
电池模组110的正极输出部1101与正电极端子151电连接，负极输出部1102与负电极端子152电连接，正电极端子151和负电极端子152设置在两个端盖中的同一端盖中，例如，正电极端子151和负电极端子152均设置在第一端盖141上。
换句话说，电池模组110的正极输出部1101和负极输出部1102设置在电池模组110沿第一方向X的同一端。
本申请一个实施例还提供了一种用电装置，用电装置可以包括前述各种实施例中的电池100，以用于为用电装置提供电能。可选地，用电装置可以为车辆、船舶或航天器。
通过在用电装置中设置前述实施例的电池100，由于在串联的第一电池单体111和第二电池单体112之间设置支架120，并使两个电池单体的连接部设置在支架的容纳空间内，可以较好地固定电池单体的连接处，防止连接处的晃动，从而降低连接处撕裂的风险；另外，支架120的存在能够增加电池模组110的整体刚度，从而方便电池模组110入壳装配。
虽然已经参考优选实施例对本申请进行了描述，但在不脱离本申请的范围的情况下，可以对其进行各种改进并且可以用等效物替换其中的部件。尤其是，只要不存在结构冲突，各个实施例中所提到的各项技术特 征均可以任意方式组合起来。本申请并不局限于文中公开的特定实施例，而是包括落入权利要求的范围内的所有技术方案。
