摘要： An electrode structure for a battery having an electrode tab coupled to a recess within an electrode lead. The tab can be coupled to the recess via hot-pressure treatment or mechanical compression. The coupling can be further reinforced by known welding techniques. The resulting electrode structure is capable of providing a battery with lowered internal resistance, enhanced safety and electrical properties.

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： 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.

摘要： A battery system having interconnected battery packs (2300) is provided. Each battery pack (2300) includes a plurality of rectangular prismatic shaped cells (300). Each cell (300) includes a positive terminal at one end and a negative terminal at the other end. The cells (300) are housed in a battery pack housing (2305) in a side-by-side manner. The cells (300) may be electrically connected in series so that the positive terminal for a cell (300) extends toward and contacts the negative terminal of an adjacent cell (300) and the negative terminal for the cell (300) extends toward and contacts the positive terminal of another adjacent cell (300).

摘要： An electrochemical storage cell is disclosed which includes at least one cathode sheet, at least one anode sheet and at least one separator sheet combined to make a core. The core is housed within a rectangular shell with four sides and two ends, sealed with an air-tight seal. The cell further includes a blow out vent in at least one of the two ends of the shell. This blow out vent is adapted to open and release excess pressure above a predetermined level to thereby prevent catastrophic rupture of the shell.
