Summary:The utility model relates to a cylindrical polymer lithium-ion battery including a positive polar membrane, a negative polar membrane and a shell. The shell is a cavity constructed from two semicircular al compound packing film; the positive polar membrane connects with the positive lifting lug, the negative polar membrane connects with the negative lifting lug. The utility solves the problem of that the ordinary battery has a low weight-specific energy, can not satisfy the need of the portable electric products.
