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.

A secondary battery structure includes a jar body, a conductive stacked structure, and two end covers. The conductive stacked structure is configured in the jar body and at least includes a battery unit. The two end covers are respectively fixed at two ends of the jar body. The end covers are assembled to the jar body by inward compression in order to eliminate dimension errors of the conductive stacked structure in the jar body. The diameter of each end cover is smaller than or substantially equal to the inner diameter of the jar body.

A packaging structure, packaging material and a packaging method for a battery pack including multiple battery cell units, multiple conductive units and one or more packaging materials are provided. The conductive units are electrically connected to the battery cell units. The packaging material is filled to gaps between the battery cell units and tightly bonded to surfaces of the battery cell units. The battery pack has an integrated structure. Therefore, the battery cell units do not move relative to each other, and breaking of connections between the battery cell units and a conductive metal line or sheet can be avoided.
