The invention provides a battery. The battery comprises a shell and a plurality of accommodating cavities positioned in the shell; every two adjacent accommodating cavities are separated by a partition plate; a pole core group is arranged in the accommodating cavity and comprises at least one pole core; the pole core groups in two adjacent accommodating cavities are connected in series; at least one partition plate is provided with a liquid guide hole, and the liquid guide hole is used for communicating two adjacent containing cavities on the two sides of the partition plate; a liquid storage groove is formed in the liquid guide hole, the liquid storage groove is sunken towards the storage position of the electrolyte in the accommodating cavity when the battery is in a use state, and the liquid storage groove is communicated with the liquid guide hole. According to the battery provided by the invention, the liquid storage grooves are formed in the liquid guide holes, so that the isolation and the safety of electrolyte among the pole core groups can be ensured. The invention also provides a battery module, a battery pack and an electric vehicle based on the battery.
本发明提供了一种电池,包括壳体和位于所述壳体内的多个容纳腔;相邻两个所述容纳腔由隔板隔开;所述容纳腔内设有极芯组,所述极芯组含有至少一个极芯;相邻两个容纳腔内的极芯组之间串联连接;至少一个所述隔板上设置有导液孔,所述导液孔用于连通此隔板两侧相邻的两个容纳腔;所述导液孔内形成有储液凹槽,所述储液凹槽朝向所述容纳腔中在所述电池处于使用状态时电解液的存储位置凹陷,所述储液凹槽与所述导液孔连通。本发明提供的电池,通过在导液孔设置储液凹槽,可保证各极芯组之间电解液的隔离及其安全性。本发明还提供基于上述电池的电池模组、电池包以及电动车。
