A central soaking member of a battery roll includes a main portion, a first electrode convergence member, a second electrode convergence member, and a connection member. The main portion is formed by a highly thermally conductive material. The first electrode convergence member and the second electrode convergence member are respectively disposed at two ends of the main portion. The connection member is formed by a highly thermally conductive and electrically insulative material, and is disposed between the main portion and the first electrode convergence member to connect the main portion and the first electrode convergence member. A temperature difference inside the battery is decreased, uniform temperature distribution inside the battery is achieved, and thermal runaway is prevented by using the central soaking member formed by a highly thermally conductive material.
