首先通过第一负极连接片和第一正极连接片能够更加充分、稳固地与相邻的两个电芯中的一个的负极极耳、另一个的正极极耳电连接,然后通过串联极柱的两端分别与第一负极连接片和第一正极连接片连接,这样也就能够更方便、且更稳固地将相邻的两个电芯以串联的方式连接起来,确保相邻的两个电芯串联的可靠性,从而确保电池的可靠性。在将电池中所有相邻的两个电芯串联后,本发明的电池能够提供数 倍于仅包括单个电芯的传统电池的电压,提高了电池的电压,为高电压平台提供了很好的电压基础,能够实现快充快放。同时,还能够减小充放电过程中的电流,以免在高电流冲击下造成电池的性能下降。并且,通过这样的设置,无需为每个电芯单独设置一个外壳,仅需在多个电芯的最外侧设置一个壳体,相邻电芯共用隔断构件作为一侧壳体,这样能够提升电池整包的能量密度,同时还能够减小电池的重量,有利于实现电池的轻量化设计。

下面结合图1至图9来阐述本发明的电池的可能的实现方式。
如图1至图3所示,电池包括壳体1、隔断构件2以及设置于壳体1内的多个电芯,隔断构件2设置成能够将壳体1内分隔成多个容纳空间,多个容纳空间沿电芯的厚度方向分布,每个电芯设置在一个容纳空间内,这样更方便后期电池的整装布置。每个电芯均设置有正极极耳和负极极耳,每个电芯的正极极耳和负极极耳分别设置在该电芯的相对设置的两个侧部。例如,按照图2所示的方位,每个电芯的正极极耳和负极极耳分别设置在该电芯的左、右两侧。显然,每个电芯的正极极耳和负极极耳也可以分别设置在该电芯的前、后两侧。
相邻的两个电芯中的一个的负极极耳与另一个的正极极耳位于电池同一侧,即相邻的两个电芯的负极极耳和正极极耳是交替设置的。本发明的电池还包括串联组件3,该串联组件3包括串联极柱31、第一负极连接片32和第一正极连接片33,第一负极连接片32分别与串联极柱31的第一端和相邻的两个电芯中的一个的负极极耳连接,第一正极连接片33分别与串联极柱31的第二端和相邻的两个电芯中的另一个的正极极耳连接,这样也就能够更方便、且更稳固地将相邻的两个电芯以串联的方式连接起来,确保相邻的两个电芯串联的可靠性,从而确保电池的可靠性。在将电池中所有相邻的两个电芯串联后,本发明的电池也就能够提供数倍于仅包括单个电芯的传统电池的电压,也就是说,通过本发明的设置方式,提高了电池的电压,为高电压平台提供了很好的电压基础,能够实现快充快放。同时,还能够减小充放电过程中的电流,以免在高电流冲击下造成电池的性能下降。并且,通过这样的设置,也就无需为每个电芯单独设置一个外壳,仅需在多个电芯的最外侧设置一个壳体1,在同样的电池整包体积下,由于无需为每个电芯的外壳预留设置空间,相邻电芯共用隔断构件2作为一侧壳体,这样能够设置电芯的空间就会相应地增大,从而也就能够提升电池整包的能量密度,同时还能够减小电池的重量,有利于实现电池的轻量化设计。
需要说明的是,电芯的厚度方向大致为图7中所示的竖直方向。
需要说明的是,多个容纳空间也可以不沿电芯的厚度方向分布,而是沿电池的长度方向(大致为图7中的左右方向)或者宽度方向(大致为图7中与纸面垂直的方向)等其他可能的方向分布。
如图2至图4、图6至图9所示并按照图7所示的方位,壳体1包括彼此扣合的第一壳体11和第二壳体12,第一壳体11位于第二壳体12的上方。电池包括相邻设置的第一电芯4和第二电芯5,第一电芯4和第二电芯5均大致为扁平状的长方体结构,第一电芯4的左端向左沿第一电芯4的长度方向(大致为图7中所示的左右方向)延伸有第一负极极耳41,第二电芯5的左端向左沿第二电芯5的长度方向(大致为图7中所示的左右方向)延伸有第一正极极耳51,第一负极极耳41和第一正极极耳51均大致为片状结构,这样也就将第一电芯4的第一负极极耳41和第二电芯5的第一正极极耳51均设置在了左侧。隔断构件2大致为板状结构,第一壳体11靠近第二壳体12的外缘(大致为图6中第一壳体11的下缘)沿其一周向向外延伸有第一折边111,第二壳体12靠近第一壳体11的外缘(大致为图6中第一壳体11的上缘)沿其一周向 向外延伸有第二折边121,第一折边111与第二折边121大致沿与隔断构件2相平的方向延伸。在组装好时,隔断构件2设置在第一壳体11与第二壳体12之间。这样通过隔断构件2就能够将壳体1内分隔成位于上侧的第一容纳空间8和位于下侧的第二容纳空间9,第一电芯4和第二电芯5分别设置在该第一容纳空间8和第二容纳空间9内。串联极柱31大致为柱状结构,第一负极连接片32和第一正极连接片33大致为片状结构。隔断构件2上设置有第一通孔21,第一负极连接片32上设置有第一透孔321,第一正极连接片33上设置有第二透孔331。串联极柱31的第一端(大致为图4中所示的串联极柱31的上端)穿过第一通孔21后伸入至第一透孔321内,并与第一透孔321通过焊接等方式电连接,第一负极连接片32的上表面与第一电芯4的第一负极极耳41的下表面通过焊接等方式电连接。串联极柱31的第二端(大致为图4中所示的串联极柱31的下端)穿过第一通孔21后伸入至第二透孔331内,并与第二透孔331通过焊接等方式电连接,第一正极连接片33的下表面与第二电芯5的第一正极极耳51的上表面通过焊接等方式电连接,这样也就实现了第一电芯4和第二电芯5的串联连接。这样也就能够在一个壳体1内设置两个电芯,提高该电池的电压。并且,假如将隔断构件2等同于一个半壳体,那么本申请也就相当于两个电芯共用一个隔断构件2作为两个电芯的一半壳体,电池整体相对于两个电芯分别设置独立外壳的方案减少了一个壳体的厚度,从而也能够提升电池整包的能量密度,有利于实现电池的轻量化设计。此外,两个电芯沿其厚度方向分布,更方便后期电池整装。并且,通过将第一电芯4和第二电芯5分别设置在两个彼此独立的容纳空间内,还能够避免第一电芯4和第二电芯5之间的电解液流通,避免因高电压分解电解液。显然,第一负极连接片32上也可以不设置第一透孔321、第一正极连接片33上也可以不设置第二透孔331,此种情形下,串联极柱31的第一端与第一负极连接片32的下表面连接、第二端与第一正极连接片33的上表面连接。
显然,第一负极极耳41和第一正极极耳51也可以设置在第一电芯4和第二电芯5的右端。
