Lithium battery pole piece capable of improving folding of pole lug

Abstract

The embodiment of the utility model provides a lithium battery pole piece capable of improving tab folding. The lithium battery pole piece comprises a pole piece body and a tab arranged at one end of the pole piece body, a first outer circle chamfer and a second outer circle chamfer are respectively arranged at two end angles of one end, close to the pole piece body, of the pole lug; a first indentation is arranged on one side surface of the tab, and a second indentation is arranged on the other side surface of the tab. According to the structure, the outer circle chamfer is arranged at the root part of the lug, so that the strength of the root part of the lug can be effectively improved; meanwhile, the indentations are arranged on the two side surfaces of the tab, so that the bending resistance of the tab can be effectively improved, the folding problem of the tab is effectively solved, and the quality and the stability of the battery are effectively ensured. By means of the structure, production procedures and labor cost do not need to be increased, simplicity and convenience are achieved, operation is easy, and economic benefits are high. The structure is simple, and the problem that the output rate is low due to tab breakage and folding in the production process can be effectively solved.
