A lithium titanate battery assembly structure

Abstract

The invention discloses a lithium titanate battery assembly structure, specifically relates to the field of battery assembly technology, comprising an external protective frame plate, an insulating groove is opened on one side of the external protective frame plate, and a battery negative electrode connecting column is arranged inside the insulating groove , three vertically stacked battery explosion-proof frames are installed at one end of the battery negative connection column, safety mechanisms are provided on both sides of the battery explosion-proof frame; the safety mechanism includes a side flame-retardant plate arranged on one side of the battery explosion-proof frame, the A cross positioning groove block is installed at one end of the side flame retardant plate. The invention adopts a safety mechanism to enable the pressure sensor to monitor the flatulence degree of the lithium battery inside the battery explosion-proof frame, and carry out early warning in real time, which can remind personnel of problems such as abnormality of the lithium battery, avoid the explosion problem caused by the flatulence of the lithium battery, improve the internal strength, and avoid easy to cause Explosion and other problems have effectively improved the safety of lithium batteries during use.

Description

technical field [0001] The present invention relates to the technical field of battery assembly, and more particularly, to a lithium titanate battery assembly structure. Background technique [0002] Lithium titanate battery is a negative electrode material for lithium ion batteries - lithium titanate, which can be composed of positive electrode materials such as lithium manganate, ternary material or lithium iron phosphate. The performance improvement of lithium titanate (LTO) battery is a single material. The improvement of performance and the comprehensive reflection of the organic integration of key materials. In order to meet the requirements of fast charging and long service life, in addition to the negative electrode material, other key raw materials of lithium-ion batteries (including positive electrode material, separator, and electrolyte) should also be produced and manufactured in combination with special engineering process experience. During the production and ...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the lithium titanate (LTO) material is used as the negative electrode material in the battery. Due to its own characteristics, the interaction between the material and the electrolyte is easy to occur and gas is released during the charge-discharge cycle reaction process. Therefore, Ordinary lithium titanate batteries are prone to flatulence, resulting in cell bulging, and the electrical performance will also drop significantly, which greatly reduces the theoretical cycle life of lithium titanate batteries, which will cause excessive flatulence and cause explosion hazards, and low safety
