Polymer lithium battery with good heat dissipation performance

Abstract

The invention relates to a polymer lithium battery with good heat dissipation performance, which comprises a placing frame, a sealing plate is fixed at the left end of the placing frame through screws, ventilation grooves are uniformly formed in the sealing plate, battery cells wrapped by aluminum-plastic composite films are uniformly placed in the placing frame, and the battery cells are connected in series through wires. According to the invention, the following problems existing in the combination and use process of the existing polymer lithium battery can be solved: a, directly binding the existing polymer lithium batteries together during combined use, and wrapping by using an aluminum-plastic composite film; b, the polymer lithium batteries which are combined and wrapped together cannot be quickly separated when the temperature of the batteries is high, only spontaneous combustion cooling of the polymer lithium batteries can be waited, the cooling speed is low, and consumed time is long.

Problems solved by technology

[0002] In order to increase the working efficiency of polymer lithium batteries in use, many groups of lithium batteries are packaged together and then used in series. The batteries are prone to heat during use. If the heated batteries are not cooled in time, it is easy to cause safety hazards or even cause the battery to spontaneously ignite

[0003] The following problems exist in the combined use of existing polymer lithium batteries, a. The existing polymer lithium batteries are directly bundled together and then wrapped with aluminum-plastic composite film when used in combination. The heat is transferred to each other, causing heat superposition, and there is a danger of high-temperature spontaneous combustion b. When the battery temperature is high, the polymer lithium battery packaged together cannot be separated quickly, and can only wait for its spontaneous combustion to cool down. The cooling speed is slow and takes a long time.

[0004] Regarding some problems existing in the use of polymer lithium batteries, related industries have made research and proposed specific technical solutions, such as the Chinese utility model patent No. The two cooling methods of air cooling dissipate the heat generated in the heat dissipation battery box, but the problems mentioned above about the combined use of polymer lithium batteries are not involved.
