可选地，所述凹槽12环绕所述防爆阀11一周设置。通过将所述凹槽12环绕所述防爆阀11一周设置，从而能够将所述防爆阀11包围，避免各个方向的电解液流向所述防爆阀11。
作为变形，所述凹槽12还可以环绕所述注液孔51设置。
可选地，所述凹槽12采用机加或冲压成型。
可选地，所述电池还包括：
凸台13，由所述壳体1的表面向外凸出而成，所述凸台13至少设置于靠近所述注液孔51一侧的所述壳体1上。
可选的，所述电池沿长度方向的至少其中一端设置有盖板5，使得电池沿长度方向的至少其中一端的所述盖板5上开设有注液孔51，通过将所述凸台13至少设置于靠近所述注液孔51一侧的所述壳体1上，从而能够在所述壳体1靠近所述注液孔51的位置形成凸台13，使得凸台13起到对电 解液的拦截作用。
当所述注液孔51位于电池沿长度方向的两端的盖板5上时，所述凸台13形成在两侧的所述壳体1上。
本实施例提供的电池，通过在壳体1的表面向外凸出形成凸台13，且凸台13至少设置于所述防爆阀11与所述注液孔51之间的位置，从而在电解液溢出时，在由注液孔51流向防爆阀11的过程中，使得凸台13能够起到阻隔作用，避免电解液直接流向防爆阀11，并且起到改向作用，以便操作人员及时发现，可以及时清洗干净，或者加热蒸发掉。
可选的，所述凸台13靠近所述防爆阀11设置。
可选地，所述凸台13环绕所述防爆阀11一周设置。通过将所述凸台13环绕所述防爆阀11一周设置，从而能够将所述防爆阀11包围，避免各个方向的电解液流向所述防爆阀11。
可选地，所述凸台13采用冲压成型。
作为可选，所述凹槽12与所述凸台13可以同时设置于所述壳体1上，例如，可以使所述凹槽12设置于靠近所述防爆阀11的内圈，将所述凸台13设置于所述防爆阀11与所述凹槽12共同的外圈。
作为变形，所述凹槽12与所述凸台13还可以环绕所述注液孔51设置。
作为变形，所述凹槽12与所述凸台13的其中一个环绕所述注液孔51设置，另一个环绕所述防爆阀11设置。
可选地，所述电池还包括：端板4，设置于所述盖板5与所述电芯2之间，所述端板4对应所述注液孔51的位置形成有过液通道；
侧板3，设置于所述壳体1内，并位于所述电芯2与所述壳体1设置有 所述防爆阀11的侧壁之间；所述侧板3对应所述防爆阀11的位置形成有镂空。
可选的，所述盖板5上还设置有极柱52。
