摘要:
Disclosed herein is a heat dissipating device for a battery pack which comprises a heat collecting plate having a heat collecting channel, a heat dissipating plate having a heat dissipating channel, and a pump, wherein, one port of the heat collecting channel is communicated with one port of the heat dissipating channel, the other post the heat collecting channel is communicated with the liquid outlet of the pump, and the liquid inlet of the pump is communicated with the other port of the heat dissipating channel. A battery pack using the heat dissipating device is also disclosed. During the operation of the heat dissipating device, the heat generated by the cells can be collected in the heat collecting plate and absorbed by the cooling liquid pumped into the heat collecting channel by the pump, the cooling liquid carrying the heat flows into the heat dissipating channel, the heat is dissipated outwardly through the heat dissipating plate, and then the cooling liquid is repeatedly pumped from the heat dissipating channel into the heat collecting channel by the pump, such that the heat generated by the cells can be dissipated rapidly and efficiently.
摘要:
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.

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.
