Abstract: 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.

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 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.

Abstract: 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.

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.

Abstract: An improved flexible toothbrush for enhancing the brushing of an individual. The flexible toothbrush comprises a bristle head portion, a neck portion and a handle portion integrally connected to the bristle head portion by the neck portion. An elongated flat flexible leaf-spring is embedded within the body of the toothbrush and extends partially in the head portion through the entire neck portion and the end of the handle portion for providing flexibility on the body of the toothbrush and enhancing the brushing of teeth of an individual. The flexible leaf-spring comprises a pair of spaced apart zig-zag sections which located between the head and neck portions and the beginning of the handle portion to further increase the flexibility on the body of the toothbrush.

Abstract: A flexible toothbrush comprises a head portion, a neck portion and a handle portion. The head portion is integrally formed with the neck portion such that it is at an angle of approximately 0.degree. to 20.degree.. The neck potion has a hollow chamber, where a leaf-spring is embedded within the hollow chamber and is bendable for providing flexibility on the neck portion for enhancing the brushing of an individual's teeth.
