Lithium battery with self-extinguishing structure

Abstract

The invention discloses a lithium battery with a self-extinguishing structure, and relates to the technical field of lithium batteries, the lithium battery comprises a fixed box body, an over-connection plate and a protective airbag, the inner side of the fixed box body is provided with a lithium battery module, the two sides of the top of the lithium battery module are provided with connection ports, and the middle ends of the outer sides of the connection ports are connected with access plates; and an over-connection plate is arranged on the outer side of the bottom of the connection port. In the using process of the lithium battery, if a single lithium battery module is damaged and cannot be normally used, a detector can detect the abnormal state of the lithium battery module, a micro motor works to drive a lead screw to rotate, and in the rotating process of the lead screw, a sliding seat can slide on the inner side of a sliding groove, so that the lithium battery module can be used normally. And the two butt joint seats are in butt joint, so that the wiring boards at the two ends of the top of the lithium battery module are communicated with the communication line, and the connection port at the left end bypasses the lithium battery module and is directly and electrically connected with the connection port at the right end.

Description

technical field [0001] The invention relates to the technical field of lithium batteries, in particular to a lithium battery with a self-extinguishing structure. Background technique [0002] Lithium batteries are a type of batteries that use lithium metal or lithium alloys as positive / negative electrode materials and use non-aqueous electrolyte solutions. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements. With the development of science and technology, lithium batteries have become the mainstream of storage batteries. [0003] Lithium batteries for electric vehicles on the market are usually composed of several lithium battery modules connected in series. Because the lithium battery modules are connected in series, during long-term use, if a single lithium battery module is damaged, the subsequent series of lithium batteries cannot continue. Performing power supply work, w...

Problems solved by technology

[0003] Lithium batteries for electric vehicles on the market are usually composed of several lithium battery modules connected in series. Because the lithium battery modules are connected in series, if a single lithium battery module is damaged during long-term use, the subsequent lithium batteries in series will not be able to continue. Perform power supply work, which will cause a significant drop in the storage capacity of the lithium battery, and require frequent repairs to replace damaged lithium batteries
