Abstract: Disclosed herein is a heat dissipating device for a battery pack which comprises a heat pipe and a heat collecting plate comprising a bottom heat collecting plate and an upper heat collecting plate each having a hole therein, wherein two ends of the heat pipe are inserted respectively into the holes in the bottom heat collecting plate and the upper heat collecting plate. A battery using the heat dissipating device is also disclosed. During the operation of the heat dissipating device, since the heat generated by the cells can be collected in the upper heat collecting plate, then transmitted to the bottom heat collecting plate through the heat pipe, and finally dissipated outwardly by the bottom heat collecting plate, the heat generated by cells can be dissipated rapidly and efficiently.

Abstract: Disclosed herein is a lithium ion battery comprising an electrode core, an electrolyte solution, a metal shell and an end cover assembly, said metal shell comprising an outer wall, an inner wall and a chamber, said electrode core and electrolyte solution being located in the chamber of the metal shell, and said electrode core being connected to the end cover assembly with a electrode terminal of the electrode core, wherein the number of said electrode core is more than one, and the multiple electrode cores are located in the chamber of the metal shell.
