摘要:
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.

A type of winding assembly type lithium ion secondary power battery includes: winding assembly type electrode cores wound with positive electrodes, negative electrodes and a separation membrane, electrolyte, and a battery shell. Its characteristics are: the interior of the battery shell carries at least one electrode units formed by electrode holders holding many stacked electrode cores. The terminal leads of the current collector for all positive and negative electrode cores are led from the upper and lower ends of the electrode unit respectively. The positive and negative terminals on cover boards and the outer side of the cover boards are connected to terminal leads of the current collector by built-in fasteners. There is a separation ring between the electrode core body of the battery and the cover boards of the battery. The present invention simplifies the manufacturing technology, increases the energy density of the battery, the mechanical property and safety property of the battery, and has an excellent high discharge property.

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.
