具体实施方式
为使本申请实施例的目的、技术方案和优点更加清楚，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
除非另有定义，本申请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；本申请中在申请的说明书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。
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。

在本申请的实施例中，相同的附图标记表示相同的部件，并且为了简洁，在不同实施例中，省略对相同部件的详细说明。应理解，附图示出的本申请实施例中的各种部件的厚度、长宽等尺寸，以及集成装置的整体厚度、长宽等尺寸仅为示例性说明，而不应对本申请构成任何限定。
本申请中出现的“多个”指的是两个以上(包括两个)。
本申请中，电池是指包括一个或多个电池单体以提供更高的电压和容量的单一的物理模块。例如，本申请中所提到的电池可以包括电池模组或电池包等。一些电池可以包括用于封装一个或多个电池单体或多个电池模组的箱体。箱体可以避免液体或其他异物影响电池单体的充电或放电。当然，还有一些电池可以不包括上述箱体，直接设置在用电装置的电池安装舱内。
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、方形电池单体和软包电池单体，本申请实施例对此也不限定。
例如，电池单体可以包括外壳、电极组件和电解液，外壳用于容纳电极组件和电解液。电极组件由正极极片、负极极片和隔离膜组成。电池单体主要依靠金属离子在正极极片和负极极片之间移动来工作。正极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正极集流体凸出于已涂覆正极活性物质层的正极集流体，未涂敷正极活性物质层的正极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负极集流体凸出于已涂覆负极活性物质层的负极集流 体，未涂敷负极活性物质层的负极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。
隔离膜的材质可以为PP(polypropylene，聚丙烯)或PE(polyethylene，聚乙烯)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。
电池单体上可以设置极柱等与极耳相连，作为电池单体的电连接部。并且，电池单体上可以具有泄压部，在电池单体内压过大(例如热失控)时，泄压部用于释放电池单体内部物质(例如气体、液体、颗粒物等)，以降低电池单体的内部压力，避免电池单体内部过快加压，而导致电池单体爆燃等危险事故。例如，泄压部可以为防爆阀、防爆片等等。
例如图1和图2所示，一些用电装置A中，采用电池B进行供电，电池B包括箱体B1和电池单体B2，箱体B1包括上壳B11和下壳B12。传统技术中，电池单体通常粘胶固定在上壳B11或下壳B12上，并且电池B整体的结构强度较差且电池单体上电连接部悬空布置。然而粘胶固定方式不牢固，尤其随着电池B使用时间增长或温度升高，会导致粘胶老化或软化，导致电池单体容易移动，尤其在发生碰撞时容易移动，进而导致电连接部与相邻部件之间的间距不稳定，影响该区域的散热，或者会降低电连接部之间的爬电间隙、导致发生高压打火等绝缘失效现象，严重的甚至导致电连接部与相邻部件发生碰撞而损坏。
为了避免电池单体发生移动时导致的电连接部损坏问题，可以对电连接部的结构进行改进，以提高其结构强度；但是，该方式仅能在撞击较轻或者撞击次数较少时起到防止电连接部损坏的作用，而不能承受较重撞击，且不能承受多次撞击带来的伤害。并且，上述方式也不能解决电连接部附近散热空间因电池单体移动而变化的问题，尤其是在一些电池中，为了使得电池具有合适的电压和容量，往往设置多个电池单体，且将多个电池单体呈多排放置，在电池单体移动时可能导致部分电池单体的电连接部对应散热空间增大，部分电池单体的电连接部对应散热空间减小，上述方式存在局部散热效果差的问题。
基于此，本申请提出了一种电池1000，包括多个结构件10和支撑件40，多个结构件10沿第一方向F1排布，其中至少一个结构件10为电池排20，电池排20包括至少一个电池单体21，电池单体21具有第一表面211，第一表面211设有电连接部22且第一表面211朝向相邻结构件10。支撑件40设于电池排20与相邻结构件10之间，且用于使第一表面211和相邻结构件10间隔开固定间隙。
在上述这种结构的电池1000中，通过支撑件40对电池单体21设有电连接部22的第一表面211与相邻结构件10进行支撑限位，使第一表面211与相邻结构件10之间间隔开固定间隙，以避免电池排20与相邻结构件10发生相对移动，从而保证设有电连接部22的区域空间尺寸固定，防止电连接部22与相邻结构件10产生碰撞而损坏。
同时通过设置支撑件40，也使电连接部22所在区域能保持稳定的散热空间，保证稳定的散热效果和散热均匀性，避免发生局部温度过高的情况。此外，在两个电池排20相邻且第一表面211相对的一些实施例中，通过设置支撑件40还保证了各导电部件之间的爬电距离，可以避免两个电池排20的电连接结构接触短路。
并且，与仅通过粘胶固定电池单体21相比，通过支撑件40限位更加可靠，不易老化或软化，支撑件40机械强度更高，能够承受更大撞击力，大大提高了使用寿命。
本申请实施例公开的电池1000可以用于、但不限用于车辆、船舶或飞行器等用电装置2000中，可以使具备本申请公开的电池1000等组成该用电装置2000的电源系统，以保证用电装置2000的使用安全性和可靠性。
例如，本申请实施例公开的用电装置2000可以是、但不限于是车辆、手机、平板、 笔记本电脑、轮船、航天器、电动玩具和电动工具等等。车辆可以是燃油车辆、或燃气车辆、或新能源车辆、或轨道车辆，新能源车辆可以是纯电动车辆、混合动力车辆或增程式车辆等；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、电动车辆玩具、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。
下面，参考附图，描述根据本申请实施例的电池1000。
如图3-图7所示，电池1000包括：多个结构件10和支撑件40。多个结构件10沿第一方向F1排布，其中至少一个结构件10为电池排20。电池排20包括至少一个电池单体21，电池单体21具有第一表面211，第一表面211设有电连接部22，且第一表面211朝向的结构件10。支撑件40设于电池排20与相邻结构件10之间，且支撑件40用于使第一表面211和相邻结构件10间隔开固定间隙。
结构件10是指构成电池1000的整体结构的部件，这里特指沿第一方向F1排布的部件。例如结构件10可以为电池排20、梁体30等。其中，梁体30可以为电池1000的箱体侧壁，也可以为设于箱体内、用于将箱体内空间进行分隔的分隔梁等。
至少一个结构件10为电池排20，换言之，多个结构件10中可以仅一个结构件10为电池排20，或者几个结构件10为电池排20，再或者多个结构件10均为电池排20。在仅一个结构件10为电池排20或者几个结构件10为电池排20的实施例中，本申请对其他非电池排20的结构件10不做特殊限制，可以为梁体30，也可以为其他与电池排20相邻的结构。
电池排20包括一个或者多个电池单体21，其中，包括多个电池单体21的一些实施例中，多个电池单体21可以垂直于第一表面211排布，以使多个电池单体21在第一方向F1上位于同一排。
每个电池单体21具有第一表面211，第一表面211上设有电连接部22。需要说明的是，在每个电池排20包括多个电池单体21的实施例中，对应同一电池排20的多个电池单体21的第一表面211在第一方向F1上可以位于相同侧，也可以位于不同侧，这都在本申请的保护范围之内。
例如图4和图5所示，电池排20包括六个电池单体21，六个电池单体21的第一表面211在第一方向F1上位于电池单体21的同一侧；再例如，电池排20包括六个电池单体21，其中三个电池单体21的第一表面211位于电池单体21沿第一方向F1的一侧，另外三个电池单体21的第一表面211位于电池单体21沿第一方向F1的另一侧。
支撑件40，即能够起到支撑作用的结构。支撑件40设于电池排20与相邻的结构件10之间，且用于使第一表面211和相邻的结构件10间隔开固定间隙。即支撑件40利用自身结构占用一定空间的特性，通过设置在电池排20与相邻结构件10之间，使第一表面211与相邻结构件10能够间隔开。例如，在一些实施例中，支撑件40沿第一方向F1的一端与第一表面211相抵，另一端与相邻的结构件10相抵，从而使第一表面211与相邻结构件10间隔开固定间隙，进而使设于第一表面211的电连接部22与相邻结构件10相对位置固定。
由于在支撑件40的作用下，第一表面211与相邻结构件10所间隔开的间隙固定，使得支撑件40能够在第一方向F1上对第一表面211和相邻结构件10进行支撑，提高整体的结构强度，并且可以防止电池排20发生移动而导致第一表面211的电连接部22与相邻结构件10发生碰撞，避免了电连接结构损坏，提高了电连接部22的结构稳定性和安全性。
同时，支撑件40还是电连接部22所在区域的空间间距稳定，保证足够的散热空间，提高散热效率。在相邻结构件10上有导电部件的实施例中，也可以防止电连接部22与 结构件10上的导电部件接触造成绝缘失效、高压打火等问题，保证电池1000中各导电部件之间的爬电间隙，以避免发生短路问题。
根据本申请实施例的电池1000，通过支撑件40使设有电连接部22的第一表面211与相邻的结构件10间隔开固定间隙，可以提高电池1000的结构强度，防止电连接部22与结构件10发生撞击，提高了电连接部22的稳定性和使用寿命。并且，支撑件40使电池1000的导电部件之间保持良好的绝缘性，防止电连接部22与其他导电部件误接触短路，保证了电池1000的使用安全性和可靠性。当本申请实施例公开的电池1000用于用电装置2000中时，用电装置2000的电源系统可以采用本申请公开的电池1000，从而可以提升用电装置2000的使用安全性和可靠性。
在本申请的实施例中，结构件10的类型可以根据实际情况灵活设置。
例如，在一些实施例中，如图6和图7所示，至少一个结构件10可以为梁体30。并且，梁体30与电池排20相邻布置，梁体30与相邻电池排20之间设有支撑件40。
换言之，多个结构件10可以包括一个梁体30，或者包括多个梁体30。其中至少一个梁体30可以与电池排20相邻布置，并且相邻布置的梁体30与电池排20之间通过支撑件40进行支撑和限位。一方面梁体30的结构强度高，通过梁体30、支撑件40与电池排20构成一个整体，整体结构强度更高，提高结构稳定性、防止电连接部22损坏的效果更好。
在一些实施例中，继续参照图6和图7所示，梁体30沿第一方向F1的两侧可以分别设有电池排20，每个电池排20与梁体30之间设有支撑件40。
也就是说，梁体30与两个电池排20在第一方向F1上相邻，并且通过支撑件40与相邻的两个电池排20进行支撑限位。由此，每个梁体30可以与两个电池排20通过支撑件40构成整体，从而提高两个电池排20的结构强度，有利于使电池1000的结构更简单。并且，梁体30可以起到分隔梁作用，将两个电池排20分隔开，避免两个电池排20的导电结构直接接触而发生短路；梁体30还可以避免在其中一个电池排20发生热失控时，热量快速传导至另一个电池排20导致连锁热失控。
再例如，在一些实施例中，如图3-图5所示，至少两个结构件10为电池排20并且相邻布置，相邻两排电池排20之间设有支撑件40。
电池1000包括至少两排电池排20，使电池1000可以具有更合适的电压和容量。而两个电池排20沿第一方向F1相邻排布时，也可以通过支撑件40进行支撑限位。一方面，避免两个电池排20的导电部件发生短路，避免两个电池排20碰撞导致结构损坏或电连接部22损坏；另一方面，两个电池排20直接相邻可以省去分隔梁等结构，使排布更紧凑、结构更简单，而支撑件40的支撑限位作用可以保证绝缘效果。
此外，电池单体21还包括与第一表面211沿第一方向F1间隔开的第二表面212，换言之，电池单体21沿第一方向F1两侧的表面分别为第一表面211和第二表面212，如电池单体21的第一表面211向左，则第二表面212向右。相邻两排电池排20的第一表面211彼此相对，或者，其中一排电池排20的第一表面211与相邻电池排20的第二表面212相对。
其中，相邻两排电池排20的第一表面211彼此相对的实施例中，如图3所示，两排电池排20的电连接部22相对布置，使两排电池排20的电连接部22可以共用两排电池排20之间的散热间隙和电连接间隙。即两排电池排20的电连接部22散热的热量均可以通过两排电池排20之间的空间散发出去，并且用于实现多个电连接部22的电连接的零部件(如汇流片24)均可以设于两排电池排20之间的空间，便于将电连接的零部件的空间位置进行调节布置，以使两排电池排20的排布更紧凑，进而电池1000的整体结构更紧凑。
举例而言，在一些实施例中，如图4和图5所示，电池排20的多个电池单体21可以通过汇流片24与电连接部22电连接，实现多个电池单体21的串联或并联，或者实 现相邻电池排20之间的串联或并联，两排电池排20所连接的汇流片24均可以走相对两个第一表面211之间的空间，并且多个汇流片24相互错开，以避免短路，也使结构更紧凑。
举例而言，在另一些实施例中，相邻电池排20的电连接部22可以抵接支撑或者通过相同的汇流片24进行电连接，以实现相邻两个电池排20的并联。并且，电连接部22的上述配合结构，还可以进一步提高电连接部22的结构强度，防止电连接部22和电池单体21结构损坏的效果更好。
其中，其中一排电池排20的第一表面211与相邻电池排20的第二表面212相对的实施例中，两排电池排20的电连接部22设于同一侧，例如均设于电池排20的左侧。此时，可以通过电池单体21的自身结构将电连接部22分隔开，防止两排电池排20的电连接部22短路的效果更好。
需要说明的是，抵接支撑可以是直接或间接止抵，可以构成电连接，也可以是绝缘，当电连接时，可以是并联或串联，这里不作限制。
在本申请的实施例中，支撑件40的结构和安装结构也可以根据实际情况灵活设置。例如，支撑件40可以仅设置在其中一个结构件10上，也可以同时设在相邻两个结构件10上。
例如，在一些实施例中，如图3-图5所示，支撑件40可以包括第一支撑台41和第二支撑台42，第一支撑台41设于第一表面211，第二支撑台42设于与第一表面211相邻的结构件10，第一支撑台41与第二支撑台42相抵。由此，可以通过第一支撑台41与第二支撑台42实现支撑，提高结构强度，且容易实现电池排20所需绝缘位置的绝缘要求。而且电池排20和相邻的结构件10(梁体30或电池排20等)均设有支撑结构，制造过程中无需对不同结构件10的支撑结构设计做区别，例如两个电池单体21相对的实施例中，两个电池单体21均设有支撑结构可以实现电池单体21的统一规格加工，可以简化加工工序，提高生产效率。
例如，在一些实施例中，如图6-图8所示，支撑件40包括支撑台43，支撑台43设于第一表面211和相邻的结构件10中的一个，且支撑台43与第一表面211和相邻的结构件10中的另一个相抵。也就是说，通过支撑件40抵接支撑的两个结构件10中，只有一个设有支撑台43，该支撑台43支撑于对侧的结构件10。由此，可以降低装配难度，避免对侧的支撑台43错位导致的支撑不稳等问题。
例如，在一些实施例中，支撑件40可以包括填充于电池排20和相邻结构件10之间的填充胶。即通过胶体也可以实现相邻两个结构件10的固定支撑，增强结构强度，从而简化电池单体21的加工。值得说明的是，支撑件40还可以同时包括支撑台43(或第一支撑台41、第二支撑台42)和填充胶等，从而进一步提高结构强度。
需要说明的是，支撑件40的加工方式不限。
在一些实施例中，电池单体21具有朝向相邻结构件10的第一端壁，第一端壁的外表面(即朝向相邻结构件10的表面)形成为第一表面211。支撑件40可以一体成型于第一端壁，或者，支撑件40可以一体成型于结构件10。由此，可以减少安装时的工序，便于成组。
在另一些实施例中，电池单体21具有朝向相邻结构件10的第一端壁，第一端壁的外表面形成为第一表面211。支撑件40可以装配于第一端壁；或者，支撑件40可以装配于结构件10。也就是说，支撑件40与第一端壁可以为分体结构，且支撑件40与结构件10为分体件，且支撑件40装配至第一端壁或者结构件10，以使支撑件40能够随电池排20或结构件10进行组装排布。而制造过程中，支撑件40可以单独制造，便于成型。这里支撑件40的装配方式包括但不限于焊接、粘胶等。
在一些实施例中，参照图8所示，电池单体21可以包括壳体214和设于壳体214的端盖215。支撑件40可以设于壳体214或者设于端盖215。由此，电连接部22可以 设于端盖215，也可以设于壳体214，使结构设计更灵活。
例如在一些具体实施例中，支撑件40一体成型于端盖215，在端盖215注塑成型过程中，可以通过注塑一次加工成支撑件40，大大简化了加工工序，提高了生产效率。
在本申请的一些实施例中，如图3-图5所示，每个第一表面211对应设有多个支撑件40，多个支撑件40环绕电连接部22设置，相邻两个支撑件40间隔开预定间隙。换言之，设于同一第一表面211的支撑件40零散设置，而非一个支撑件40沿第一表面211呈整周的环形结构，从而可以留出空间，方便进行电连接和走线。同时，周向间隔支撑保证了支撑稳定性和结构可靠性。
在一些具体实施例中，如图4和图5所示，第一表面211具有四个角部，例如第一表面211大体为矩形面，形成较为规整的结构。四个角度分别设有支撑件40。使支撑件40能够从四个角度对电池单体21进行支撑限位，电池单体21整体受力更均匀，结构更稳定，并且支撑件40靠近边缘位置，角部也更不易与电连接结构产生干涉。
当然，支撑件40的设置位置包括但不限于第一表面211的角部，例如支撑件40还可以设于第一表面211的长边的中部等位置，只需要满足避免与电连接部22和电连接结构(如汇流片24)干涉的要求即可。
在第一表面211设有多个支撑件40的一些实施例中，如图4和图5所示，电池1000还可以包括汇流片24，汇流片24可以用于连接相邻两个电池单体21的电连接部22，即相邻两个电池单体21通过汇流片24实现电连接，如串联或者并联，从而可以降低工艺难度。
此外，在平行于第一表面211的方向上，汇流片24位于相邻两个支撑件40之间，以使汇流片24与支撑件40沿第一方向F1在第一表面211的投影完全不重叠，汇流片24和支撑件40完全错开，避免产生位置干涉。
需要说明的是，在上述实施例中，汇流片24的延伸方向可以灵活设置，只需要满足串并联需求，且汇流片24与支撑件40间隔开的要求即可。
在本申请的一些实施例中，如图6-图8所示，电连接部22包括第一极柱221和第二极柱222，第一极柱221和第二极柱222中的一个可以为正极极柱，另一个可以为负极极柱，以使电池单体21可以通过正极极柱和负极极柱实现与其他电池单体21的串并联。
此外，支撑件40可以设于第一极柱221和第二极柱222之间。以通过更少数量的支撑件40起到良好的支撑和限位效果，保证整体的结构稳定性，同时简化结构。并且，支撑件40设于第一极柱221和第二极柱222之间，有利于减小支撑件40与极柱之间的间距，避免支撑件40与极柱间距过长导致极柱附近支撑力较弱，有效降低热失控时第一表面211有膨胀凸起导致打火的风险。
进一步地，如图6-图8所示，在垂直于第一极柱221和第二极柱222的排布方向上，支撑件40的至少一端延伸至第一表面211的边沿。例如第一极柱221和第二极柱222可以沿第三方向F3排布，支撑件40沿第二方向F2的至少一端延伸至第一表面211的边沿，第一方向F1、第二方向F2和第三方向F3两两垂直。由此，可以增大支撑件40的支撑面积，提高支撑效果和结构强度。
在本申请的一些实施例中，如图4-图7所示，电池排20包括沿第二方向F2层叠排布的多层电池层23，每层电池层23包括沿第三方向F3排布的多个电池单体21。第一方向F1、第二方向F2和第三方向F3两两垂直。通过调节电池层23的层数和电池层23所包括电池单体21的个数，可以使电池1000可以在三维空间内更灵活地设计尺寸，以满足不同的空间排布需求、安装空间需求、电容电量需求等。
在电连接部22通过汇流片24进行电连接且支撑件40设于第一极柱221与第二极柱222之间的一些实施例中，汇流片24可以采用如图5所示的布线方式，即相邻两层电池层23的电池单体21通过沿第二方向F2延伸的汇流片24连接，同一电池层23的 相邻两个电池单体21通过沿第三方向F3延伸的汇流片24连接。以使每个汇流片24均不经过同一第一表面211上第一极柱221和第二极柱222之间的区域，从而避免与支撑件40发生结构干涉。并且，同一电池单体21上分别与第一极柱221和第二极柱222相连的两个汇流片24可以通过支撑件40分隔开，以提高绝缘效果，降低发生短路或打火的风险。
在一些实施例中，如图4和图5所示，每个电池排20的多个电池单体21可以电池排20内电连接，然后一体对外输出，也就是说，相邻电池排20之间不连接。由此可以简化电连接。
在另一些实施例中，相邻电池排20之间可以电连接，例如通过汇流片24电连接，从而可以降低工艺难度；或者通过对置的电连接部22直接对焊，由此可以提高结构紧凑性，优化空间利用率。
根据本申请的一些实施例，如图3所示，在第一方向F1上，相邻两排电池排20的第一表面211相对，且相对两个第一表面211的间距为H1，电连接部22的高度为H2，其中，2H2+3mm≤H1。
其中，相对的两个第一表面211的间距即为支撑件40沿第一方向F1的尺寸，通过支撑件40的两端分别与两个第一表面211相抵，使两个第一表面211间隔开固定间隙H1，即两排电池排20间隔开固定间隙。电连接部22的高度即电连接部22位于第一表面211外的部分沿第一方向F1的尺寸。
通过2H2+3mm≤H1，使支撑件40对两个第一表面211支撑限位后，两个第一表面211上的电连接部22之间间隔开一定间隙，以便于进行电连接和走线，并且为散热提供足够的空间。此外，即使发生撞击导致支撑件40轻微变形，也不会直接导致电连接部22变形，更利于保证电连接结构的稳定性。
需要说明的是，在电池排20的第一表面211与梁体30相邻的实施例中，第一表面211与梁体30的间距为H1，电连接部22的高度为H2，其中，H2+1.5mm≤H1。由此为该电池排20的电连接部22提供走线空间和散热空间，同时防止在支撑件40发生轻微变形时导致电连接结构损坏。
在本申请的一些实施例中，如图3-图5所示，在平行于第一表面211的方向上，支撑件40与电连接部22的间距为L，第一表面211的长度为M，5mm≤L≤2/3M。
这里，支撑件40与电连接部22的间距为二者之间的最短距离。第一表面211的长度是指，第一表面211彼此间隔最大的两侧边的间距，例如图4所示，第一表面211大体为长方形，长方形的长度即为第一表面211的长度M。
通过5mm≤L≤2/3M，避免支撑件40与电连接部22的间距过小导致二者发生干涉，或者导致支撑件40影响电连接部22的电连接；也避免支撑件40与电连接部22的间距过长导致电连接部22附近的支撑力较弱，有效降低了热失控时第一表面211上电连接处膨胀凸起发导致打火的风险。
在本申请的一些实施例中，如图3-图5所示，第一表面211的面积为S1，每个第一表面211连接有n个支撑件40，每个支撑件40垂直于第一方向F1的截面积为S2，其中，其中n为大于等于1的整数。
n个支撑件40的面积之和过小会导致支撑力不足，过大会导致材料浪费且支撑件40易与电连接部22等结构间隙过小。而在上述比例范围内，支撑件40能够为相邻两个结构件10提供稳定支撑，有效提高整体的结构强度，而且可以使支撑件40与电连接部22之间有足够间隙，避免结构干涉，避免影响走线。
在本申请的一些实施例中，如图3-图5所示，第一表面211与相邻结构件10的间距为H1，第一表面211的面积为S1，每个第一表面211连接有n个支撑件40，每个支 撑件40垂直于第一方向F1的截面积为S2，第一表面211的长度为M，其中，
为了保证支撑稳定性，H1/M越大，所需支撑件40的面积越大；S1越大，所需支撑件40的面积越大。通过使n个支撑件40能够为电池排20与相邻结构件10提供稳定支撑，并且避免支撑件40的面积过大导致与电连接部22的间隙过小，避免结构干涉，便于进行电连接和走线。
在本申请的一些实施例中，如图3-图5所示，每个第一表面211连接有n个支撑件40，每个支撑件40平行于第一表面211的最大尺寸为D，第一表面211的长度为M且宽度为N，其中，和/或，
支撑件40平行于第一表面211的最大尺寸，是指支撑件40垂直于第一方向F1的截面上，在垂直于第一方向F1上的最大尺寸。例如支撑件40的截面为圆形时，最大尺寸D为圆形的直径；在支撑件40的截面为正方形时，最大尺寸D为正方形的对角线长度。当然，支撑件40的形状包括但不限于圆形和正方形，例如还可以为三角形、长条形等。
第一表面211的长度指第一表面211彼此间隔最大的两侧边的间距，第一表面211的宽度指垂直于长度方向上第一表面211的尺寸。例如图4所示，第一表面211大体为长方形，长方形的长度即为第一表面211的长度M，长方形的宽度即为第一表面211的宽度N。
在一些实施例中，在另一些实施例中，在又一些实施例中，且在上述比例范围内，可以使支撑件40的尺寸足够大，以保证足够的支撑稳定性，同时避免支撑件40的尺寸过大而影响相邻电池单体21之间走线。
根据本申请的一些实施例，如图3-图7所示，电池排20包括沿第二方向F2层叠排布的至少一层电池层23，每层电池层23包括沿第三方向F3排布的至少一个电池单体21，第一方向F1、第二方向F2和第三方向F3两两垂直。以使电池排20能够灵活布置多个电池单体21，满足不同电池1000尺寸要求、电容电量要求。
在一些实施例中，电池单体21沿第二方向F2的尺寸小于沿第一方向F1的尺寸，且电池单体21沿第二方向F2的尺寸小于沿第三方向F3的尺寸。
也就是说，电池层23沿电池单体21的厚度方向层叠布置，电池单体21沿第一方向F1的尺寸可以大于、等于或小于沿第三方向F3的尺寸。可以理解的是，电池单体21的厚度小于电池单体21的长度，且电池单体21的厚度小于电池单体21的宽度，电池单体21的长度大于电池单体21的宽度。其中，电池层23沿尺寸最小的厚度方向层叠布置，有利于减小电池1000的整体厚度。
例如在一些具体实施例中，电池1000用于用电装置2000中时，第二方向F2沿竖直方向延伸，相当于电池单体21的厚度方向为竖直方向，此时电池单体21相当于是平躺设置，占用的竖向空间较小，减小电池1000的整体高度。
并且，电池单体21垂直于第二方向F2的表面面积较大，电池单体21发生膨胀时最大膨胀力是向上和向下的。可以通过减少电池排20所包括电池层23的层数，以降低电池单体21最大膨胀力对电池1000的影响，甚至可以忽略电池单体21最大膨胀力对电池1000的影响，例如电池层23可以为2层。
在一些实施例中，电池单体21沿第三方向F3的尺寸小于沿第二方向F2的尺寸，且沿第二方向F2的尺寸小于沿第一方向F1的尺寸。也就是说，电池层23沿电池单体21的宽度方向层叠布置，这也可以降低电池1000的整体高度。并且，第一表面211为非最大面，换言之电连接部22设于电池单体21的较小侧面，可以降低设置电连接部22处的膨胀变形，提高电连接结构的稳定性，降低打火风险。
根据本申请的一些实施例，如图3和图6所示，电池单体21还设有泄压部25。在电池单体21内压过大(例如热失控)时，泄压部25用于释放电池单体21内部物质(例如气体、液体、颗粒物等)，以降低电池单体21的内部压力，避免电池单体21内部过快加压，而导致电池单体21爆燃等危险事故。例如，泄压部25可以为防爆阀、防爆片等等。
此外，泄压部25与电连接部22设于电池单体21的不同侧。有利于保证电池单体21的电连接部22和泄压部25之间具有较大的间距，以有效避免在热失控等情况下，电池单体21通过自身泄压部25排放的排放物中的导电颗粒等流至自身电连接部22造成绝缘失效、高压打火等问题，保证电池1000中各导电部件之间的爬电间隙，以避免发生短路问题。
在一些实施例中，如图3和图6所示，电池单体21具有与第一表面211沿第一方向F1间隔开的第二表面212，泄压部25设于第二表面212。换言之，泄压部25与电连接部22分别的设于电池单体21彼此相背的两侧表面。由此，可以进一步拉远电连接部22与泄压部25之间的距离，可以更好地保证电连接部22免受泄压部25排出的排放物的影响，即受影响概率更小，电池1000的使用安全性和可靠性更好。
并且，在相邻两个结构件10均为电池排20的实施例中，如图3和图6所示，两排电池排20的第一表面211相对，将泄压部25设于两排电池排20的彼此远离侧。即每排电池排20中的电池单体21，朝向另一排电池排20的表面为第一表面211，背向另一排电池排20的表面为第二表面212，电连接部22设于第一表面211，泄压部25设于第二表面212。
由此，同一电池排20中的各电池单体21的泄压部25均不朝向本电池排20中的任一电连接部22喷发，也不朝向相邻电池排20的任一电连接部22喷发，从而可以有效保证各电池单体21的电连接部22免受其他电池单体21排出的排放物的影响，保证了电池1000的使用安全性和可靠性。
在另一些实施例中，电池单体21具有与第一表面211相连的周面，泄压部25设于周面。例如，电池单体21具有彼此相背的第一表面211和第二表面212，周面为连接在第一表面211和第二表面212之间的面。
由此，电连接部22与泄压部25分别位于电池单体21的相邻侧，可以使得电连接部22与泄压部25之间具有一定的安全距离，降低泄压部25排出的排放物对电连接部22的影响，提高电池1000的使用安全性和可靠性。
根据本申请第二方面实施例的用电装置2000，包括根据本申请上述第一方面实施例的电池1000，电池1000用于为用电装置2000提供电能。由此，通过采用上述的电池1000，有利于提升用电装置2000的使用安全性和可靠性。
可选地，如图9所示，当电池1000用于车辆时，电池1000可以设置在车辆的底部、或头部、或尾部。电池1000可以用于车辆的供电，例如，电池1000可以作为车辆的操作电源。车辆还可以包括控制器和马达，控制器用来控制电池1000为马达供电，例如，用于车辆的启动、导航和行驶时的工作用电需求。
下面结合附图描述根据本申请一个具体实施例的电池1000和具有其的车辆。
如图9所示，电池1000设于车辆的底部，并且如图3-图4所示，电池1000包括箱体和设于箱体内且沿第一方向F1排布的四个结构件10，第一方向F1为第一水平方向。位于中间的两个结构件10均为电池排20；位于两端的两个结构件10为梁体30，梁体30设有散热通道和水冷通道。
每个电池排20包括沿第二方向F2排布的两层电池层23，每层电池层23包括沿第三方向F3排布的三个电池单体21，每个电池单体21的长度方向沿第三方向F3延伸，宽度方向沿第一方向F1延伸，高度方向沿第二方向F2延伸。第二方向F2为竖直方向，第三方向F3为与第一水平方向垂直的第三水平方向。即每个电池单体21均平躺布置，以降低电池1000整体高度，便于在车辆底部的布置。
每个电池单体21包括壳体214和设于壳体214第一方向F1一端的端盖215，端盖215的外表面形成为第一表面211，第一表面211设有电连接部22，电连接部22包括第一极柱221和第二极柱222，分别为正极极柱和负极极柱。壳体214上与端盖215相对的端壁设有泄压部25，泄压部25与梁体30相对，以使泄压部25排出的高温气体能够通过散热通道排出。
两排电池排20的第一表面211相对，且通过支撑件40使两排电池排20的第一表面211间隔开固定间隙。支撑件40采用绝缘设计且包括第一支撑台41和第二支撑台42，第一支撑台41和第二支撑台42分别设于相对的两个第一表面211，形成为凸台。每个支撑台的高度大于同一第一表面211上电连接部22的高度，并且第一支撑台41与第二支撑台42相抵并通过结构胶固定，以实现支撑限位，可以大大增加电池1000的结构强度和稳定性。
并且，每个第一表面211的四个角部分别设有一个支撑件40，第一极柱221和第二极柱222设于第一表面211中部且沿第三方向F3间隔开。同一电池排20的六个电池单体21通过汇流片24串联，然后整体输出。一些汇流片24相对于第二方向F2倾斜延伸，以连接两层电池层23的相邻两个电池单体21，另一些汇流片24沿第三方向F3延伸，以连接同一电池层23的相邻两个电池单体21。
通过在电池单体21表面设计有一定力学强度的支撑台，在电池单体21组装成电池1000后，可以增加电池1000整体的强度和稳定性，特别是本身缺乏支撑结构的电芯高度方向(即第一方向F1)，防止电池1000整体变形以及内部电池单体21位置、距离发生变化，避免造成安全风险。
需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互结合。
以上仅为本申请的优选实施例而已，并不用于限制本申请，对于本领域的技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的保护范围之内。
