Abstract
The utility model discloses a lithium battery top cover structure, which relates to the technical field of batteries and comprises a top cover piece and lower plastic connected with the top cover piece, and a pressure relief channel is arranged on the lower plastic. The pressure relief channel comprises a longitudinal channel and a transverse channel, the longitudinal channel and the transverse channel are in a vertical state, and separators are arranged at air inlets of the longitudinal channel and the transverse channel. The utility model has the advantages that: the pressure relief channel of the lower plastic is provided with a baffle structure, so that floccules such as pole pieces and diaphragms can be blocked and stored in a certain space and are not completely sealed, and enough gas channels are reserved to facilitate timely pressure relief; a plurality of pressure relief structures for removing materials are arranged in the middle of the lower plastic, and compared with an example, stress concentration generated by plastic expansion can be discharged in a certain space.
