下面结合附图和实施例对本申请的实施方式作进一步详细描述。以下实施例的详细描述和附图用于示例性地说明本申请的原理，但不能用来限制本申请的范围，即本申请不限于所描述的实施例。
除非另有定义，本文所使用的所有的技术和科学术语与属于本申请的技术领域的技术人员通常理解的含义相同；本文中所使用的术语只是为了描述具体的实施例的目的，不是旨在于限制本申请；本申请的说明书和权利要求书及上述附图说明中的术语“包括”和“具有”以及它们的任何变形，意图在于覆盖不排他的包含。
本申请的说明书和权利要求书或上述附图中的术语“第一”、“第二”等是用于区别不同对象，而不是用于描述特定顺序或主次关系。
在本申请中提及“实施例”意味着，结合实施例描述的特定特征、结构或特性可以包含在本申请的至少一个实施例中。在说明书中的各个位置出现该短语并不一定均是指相同的实施例，也不是与其它实施例互斥的独立的或备选的实施例。本领域技术人员显式地和隐式地理解的是，本申 请所描述的实施例可以与其它实施例相结合。
在本申请的描述中，需要说明的是，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”、“附接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本申请中的具体含义。
本申请中术语“和/或”，仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：存在A，同时存在A和B，存在B这三种情况。另外，本申请中字符“/”，一般表示前后关联对象是一种“或”的关系。
本申请中出现的“多个”指的是两个以上(包括两个)，同理，“多组”指的是两组以上(包括两组)，“多片”指的是两片以上(包括两片)。
电池技术的发展要同时考虑多方面的设计因素，例如，能量密度、放电容量、充放电倍率等性能参数，另外，还需要考虑电池的装配效率。
电池单体组包括层叠设置且电连接的多个电池单体，结构紧凑，占用较小的装配空间。
电池包括箱体、分隔梁和电池单体组，分隔梁和电池单体组设置于箱体内，分隔梁将箱体的内部空间分隔为多个空间，多个空间分别设置电池单体组和其他部件(如线束等)。在一些实施例中，分隔梁的两侧均设置电池单体组，这两个电池单体组通过连接构件电连接，连接构件通常悬空设置，也即，连接构件位于分隔梁的上方，连接构件的两端分别连接于两个电池单体组，此种情况下，连接构件仅连接于两个电池单体组，连接构件与电池单体组的连接可靠性较差，当电池受到振动时，连接构件与电池单体组的连接处容易损坏，进而引发安全风险。
鉴于此，为了解决连接构件与电池单体组的连接可靠性较差导致的电池的安全性较差的问题，发明人经过深入研究，设计了一种技术方案，通过将连接构件固定于固定座，约束连接构件的移动，降低因连接构件移动而导致的连接构件与电池单体组的连接处损坏的风险，来提高电池的安全性。
在这样的电池中，固定座设置于分隔梁，连接构件固定于固定座，连接构件与分隔梁装配稳定，在电池受到振动时，连接构件能够被固定座约束，连接构件相对于分隔梁移动困难，能够减低连接构件与电池单体组的连接处损坏的风险，使得电池具有较高的安全性。
本申请实施例公开的电池可以但不限用于车辆、船舶或飞行器等用电设备中。可以使用具备本申请公开的电池组成该用电设备的电源系统。

在电池100中，电池单体21可以是多个，多个电池单体21之间可串联或并联或混联，混联是指多个电池单体21中既有串联又有并联。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21之间的电连接。
其中，电池单体21可以为二次电池或一次电池；电池单体21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。

分隔梁30为设置于箱体10内的部件，分隔梁30用于将箱体10内部分隔出多个空间，多个空间能够分别容纳电池单体组和其他部件(如线束等)。同时，分隔梁30设置于箱体10内，还能够提高箱体10的整体强度。
分隔梁30的材质可以与箱体10的材质相同，也可以与箱体10的材质不同。分隔梁30的材质可以为铝、铝合金、不锈钢等，具有较高的强度。

连接构件40为用于实现第一电池单体组201和第二电池单体组202电连接的部件，连接构件40的材质可以为铝、铜等。
连接构件40固定于固定座50是指，连接构件40的移动被固定座50约束，例如，连接构件40与固定座50位置相对固定，连接构件40不相对于固定座50移动，或者，连接构件40与固定座50之间具有较大的摩擦力，连接构件40相对于固定座50移动困难。可选地，连接构件40通过螺栓固定于固定座50，或者，连接构件40与固定座50卡接。
根据本申请实施例的电池100，连接构件40固定于固定座50，固定座50设置于分隔梁30，使得连接构件40的移动被固定座50约束，提高了连接构件40与电池单体组(第一电池单体组201和第二电池单体组202的统称，下文相同)的连接可靠性，降低因连接构件40移动而导致的连接构件40与电池单体组的连接处损坏的风险，进而使得电池100具有较高的安全性。

在上述方案中，连接构件40的一部分被第一槽侧面511和第二槽侧面512夹持，使得连接构件40的移动被第一槽侧面511和第二槽侧面512限制，连接构件40相对于固定座50移动困难，进而使得连接构件40与第一电池单体组201和第二电池单体组202连接可靠。
在电池100装配的过程中，可以先确定连接构件40的位置，将连接构件40固定于固定座50后，再将连接构件40与第一电池单体组201和第二电池单体组202连接，以确保连接构件40与第一电池单体组201和第二电池单体组202的连接精度。

请参见图3，根据本申请的一些实施例，第一电池单体组201和第二电池单体组202均包括沿第一方向X层叠设置的多个电池单体21。
在上述方案中，第一电池单体组201和第二电池单体组202中的多个电池单体21沿第一方向X层叠设置，一方面，便于实现第一电池单体组201和第二电池单体组202的电连接，另一方面，箱体10在第一方向X上的空间利用率较高。
第一电池单体组201中的电池单体21的结构与第二电池单体组202中的电池单体21的结构相同，为了便于描述，本申请中的电池单体21为第一电池单体组201中的电池单体21和第二电池单体组202中的电池单体21的统称。
请参见图8，并进一步参见图12，图12为本申请一些实施例提供的电池的部分结构示意图。根据本申请的一些实施例，电池单体21包括外壳211和电极端子212，外壳211具有垂直于第一方向X的第一壁2111，电极端子212安装于第一壁2111，电极端子212具有第一表面2121，第一表面2121所在平面与第一壁2111相交，连接构件40的一端连接于第一电池单体组201中最靠近分隔梁30的一个电池单体21的电极端子212的第一表面2121，连接构件40的另一端连接于第二电池单体组202中最靠近分隔梁30的一个电池单体21的电极端子212的第一表面2121。
外壳211包括壳体和盖体，壳体具有开口，盖体封闭开口，以将电池单体21的内部环境与外部环境隔绝。
壳体是用于配合盖体以形成电池单体21的内部环境的组件，其中，形成的内部环境可以用于容纳电极组件、电解液以及其他部件。壳体和盖体可以是独立的部件。壳体可以是多种形状和多种尺寸的。具体地，壳体的形状可以根据电极组件的具体形状和尺寸大小来确定。壳体的材质可以是多种，比如，铜、铁、铝、不锈钢、铝合金、塑胶等，本申请实施例对此不作特殊限制。本申请实施例以壳体为长方体形为例介绍。
盖体是指盖合于壳体的开口处以将电池单体21的内部环境隔绝于外部环境的部件。不限地，盖体的形状可以与壳体的形状相适应以配合壳体。可选地，盖体可以由具有一定硬度和强度的材质(如铝合金)制成，这样，盖体在受挤压碰撞时就不易发生形变，使电池单体21能够具备更高的结构强度，安全性能也可以有所提高。盖体上可以设置有如电极端子212等的功能性部件。电极端子212可以用于与电极组件电连接，以用于输出或输入电池单体21的电能。盖体的材质也可以是多种的，比如，铜、铁、铝、不锈钢、铝合金、塑胶等，本申请实施例对此不作特殊限制。在一些实施例中，在盖体的内侧还可以设置有绝缘结构，绝缘结构可以用于隔离壳体内的电连接部件与盖体，以降低短路的风险。示例性的，绝缘结构可以是塑料、橡胶等。
电池单体21还包括电极组件，电极组件是电池单体21中发生电化学反应的部件。壳体内可以包含一个或更多个电极组件。电极组件主要由正极极片和负极极片卷绕或层叠放置形成，并且通常在正极极片与负极极片之间设有隔离膜，隔离膜用于分隔正极极片和负极极片，以避免正极极片和负极极片内接短路。正极极片和负极极片具有活性物质的部分构成电芯组件的主体部，正极极片和负极极片不具有活性物质的部分各自构成极耳。正极极耳和负极极耳可以共同位于主体部的一端或是分别位于主体部的两端。在电池100的充放电过程中，正极活性物质和负极活性物质与电解液发生反应，极耳连接电极端子212以形成电流回路。
第一壁2111为外壳211的与第一方向X垂直的壁。第一壁2111可以为盖体，或者，第一壁2111也可以为壳体的一个壁。可选地，第一壁2111为盖体，以便于电极端子212与第一壁2111的装配。
电极端子212安装于第一壁2111，电极端子212具有第一表面2121和第一端面，第一端面为电极端子212的背离第一壁2111的表面，第一表面2121所在平面与第一壁2111和第一端面相交。
请参见图13，图13为本申请一些实施例提供的电极端子与第一壁的配合示意图，第一表面2121所在的平面与第一壁2111相交，可以为第一表面2121所在的平面与第一壁2111的厚度方向平行，或者，可以为第一表面2121所在的平面与第一壁2111的厚度方向倾斜设置。例如，第一表面2121所在的平面与第一壁2111之间的角度θ为60°～120°；较优地，第一表面2121所在的平面与第一壁2111之间的角度θ为85°～95°；优选地，第一表面2121所在的平面可以垂直于第一壁2111，也即，第一表面2121所在的平面可以与第一壁2111的厚度方向平行，以便于第一表面2121与连接构件40连接。
第一表面2121可以与连接构件40焊接，以使得连接构件40与电极端子212连接牢固。
在上述方案中，电极端子212设置于外壳211的垂直于第一方向X的第一壁2111，以便于实现多个电池单体21之间的连接，以及第一电池单体组201和第二电池单体组202与连接构件40的连接。

基壁41的沿第一方向X的两端分别连接于两个端壁42，两个端壁42和两个翻边部43对应设置。
每个翻边部43从对应的端壁42的远离基壁41的一端向背离另一个端部的方向延伸，以便于翻边部43与对应的电池单体21的电极端子212的第一表面2121连接。
基壁41、两个端壁42和两个翻边部43可以一体成型，例如，冲压成型。
连接构件40可以为折弯结构，端壁42相对于基壁41折弯，翻边部43相对于端壁42折弯。
在上述方案中，连接构件40的结构形式，使得连接构件40具有较高的强度，翻边部43与电极端子212的第一表面2121连接，能够减少第一方向X上的空间占用，提高箱体10在第一方向X上的空间利用率。

第一安装槽51为固定座50的用于容纳基壁41的槽，基壁41的至少一部分夹设于第一槽侧面511和第二槽侧面512之间。
在上述方案中，基壁41夹设于第一槽侧面511和第二槽侧面512之间，使得基壁41的移动被第一槽侧面511和第二槽侧面512限制，进而使得连接构件40与第一电池单体组201和第二电池单体组202的连接可靠。
请参见图8，根据本申请的一些实施例，基壁41包括相对设置的第二表面411和第三表面412，两个端壁42凸出于第二表面411，第一槽侧面511与第二表面411相对设置，第二槽侧面512与第三表面412相对设置；第一槽侧面511在第二表面411上的投影沿第一方向X的尺寸为L1，第二槽侧面512在第三表面412上的投影沿第一方向X的尺寸为L2，满足，L1＜L2。

第一槽侧面511与第二表面411相对设置，第一槽侧面511可以与第二表面411平行。第二槽侧面512与第三表面412相对设置，第二槽侧面512可以与第三表面412平行。
第一槽侧面511在第二表面411上的投影是指，第一槽侧面511沿基壁41的厚度方向在第二表面411上的投影。同理，第二槽侧面512在第三表面412上的投影是指，第二槽侧面512沿基壁41的厚度方向在第二表面411上的投影。
当第一槽侧面511和第二槽侧面512夹持基壁41时，第一槽侧面511可以与第二表面411贴合，第二槽侧面512可以与第三表面412贴合，此时，第一槽侧面511在第二表面411上的投影可以为第一槽侧面511与第二表面411的重叠区域，第二槽侧面512在第三表面412上的投影可以为第二槽侧面512与第三表面412的重叠区域。
在上述方案中，由于L1小于L2，基壁41与第二槽侧面512具有较大的重叠面积，以便于固定座50对连接构件40具有较好的约束效果；同时，两个端壁42凸出于第二表面411，第一槽侧面511与第二表面411相对设置，降低固定座50与连接构件40装配干涉的风险。
请参见图8，根据本申请的一些实施例，第一电池单体组201的电池单体21的第一壁2111面向分隔梁30设置，第二电池单体组202的电池单体21的第一壁2111背离分隔梁30设置。

请参见图6和图8，根据本申请的一些实施例，固定座50还包括第三安装槽53，第一电池单体组201的最靠近分隔梁30的电池单体21的电极端子212的一部分位于第三安装槽53内。
第三安装槽53可以由固定座50的面向第一电池单体组201的表面沿第一方向X朝第二电池单体组202凹陷形成。由于第一电池单体组201的第一壁2111面向分隔梁30设置，使得，第一电池单体组201的最靠近分隔梁30的电池单体21的电极端子212朝向分隔梁30凸出，该电极端子212的凸出部分的一部分能够容纳于第三安装槽53内。
在上述方案中，第一电池单体组201的最靠近分隔梁30的电池单体21的电极端子212的一部分位于第三安装槽53内，降低连接构件40与该电极端子212连接后的结构在第一方向X上的空间占用，合理利用箱体10的内部空间，使得电池100具有较高的能量密度。

第一壁2111、第二壁2112、第三壁、第四壁、第五壁和第六壁为构成外壳211的壁，这些壁可以围成用于容纳电极组件的空间。
在上述方案中，第一壁2111和第二壁2112为外壳211的面积较大的壁，多个电池单体21沿垂直于第一壁2111的第一方向X层叠设置，使得第一电池单体组201和第二电池单体组202结构紧凑，使得电池100具有较高的能量密度。
请参见图8和图12，根据本申请的一些实施例，外壳211还具有与第一壁2111相对设置的第二壁2112，第二壁2112的边缘的第一区域内陷形成第二凹部2113，第二凹部2113用于容纳与第二壁2112相邻的电池单体21的电极端子212。
第二壁2112与第一壁2111沿第一方向X相对设置。第一区域为第二壁2112的边缘的区域，沿第一方向X，第一区域与第一壁2111的安装电极端子212的区域相对应。第一区域沿第一方向X朝向第一壁2111凹陷形成第二凹部2113。
在一些实施例中，第二凹部2113的凹陷深度大于电极端子212凸出第一壁2111的高度。可以理解的，与第二壁2112相邻的电池单体21的电极端子212也可以只有部分容纳于第二凹部2113内。
第二壁2112的表面可以设置有绝缘结构，以便于在多个电池单体21层叠设置时，第二壁2112与相邻的电池单体21的电极端子212绝缘隔离。绝缘结构也可以设置在电极端子212远离第一壁2111的表面，以便于在多个电池单体21层叠设置时，电极端子212可以与第一壁2111
在上述方案中，第二凹部2113的设置，能够容纳与第二壁2112相邻的电池单体21的电极端子212，使得电池单体组结构紧凑，从而使得电池100具有较高的能量密度。
