Abstract: A stacked-type lithium ion battery, comprising a core, a battery shell, and a cover plate; said core is placed in the battery shell, said cover plate is coupled to the battery shell in a sealed manner; said core comprises a plurality of layers of positive plates, negative plates, and membranes that are stacked together with each other, and the membrane is between the positive plate and the negative plate; wherein at least two membranes are in a 5-175° included angle between their tensile directions. Since the tensile directions of the membranes are different, the overall tensile strengths of the battery in all tensile directions are essentially same; therefore, the phenomenon of short circuit in the battery resulted from membrane rupture in lower tensile strength directions can be prevented, and the battery safety performance is greatly enhanced.
