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 colleted 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: The present invention relates to lithium ion secondary batteries that have an enclosure with an electrode core compartment for holding the electrode core and a separate protection circuit compartment for holding the protection circuits, and terminal leads connecting the electrodes in the electrode core with the circuits in the protection circuit. The enclosure is made of non-conducting material such as plastic. The lithium batteries of this invention are light, not only because of the weight of the material of their enclosure, but also because its non-conducting character eliminates the necessity of additional protective features that are commonly necessary for enclosures with metal components.
