Lithium titanate battery assembly structure

Abstract

The invention discloses a lithium titanate battery assembly structure, and particularly relates to the technical field of battery assembly.The lithium titanate battery assembly structure comprises an external protection frame plate, an insulation groove is formed in one side of the external protection frame plate, a battery negative electrode connecting column is arranged in the insulation groove, and three vertically-stacked battery explosion-proof frames are installed at one end of the battery negative electrode connecting column; safety mechanisms are arranged on the two sides of the battery explosion-proof frame; the safety mechanism comprises a side flame-retardant plate arranged on one side of the battery explosion-proof frame, and a cross-shaped positioning groove block is mounted at one end of the side flame-retardant plate. The safety mechanism is adopted to enable the pressure sensor to monitor the expansion degree of the lithium battery in the battery explosion-proof frame, early warning is carried out in real time, people can be reminded of the problems such as abnormity of the lithium battery, the explosion problem caused by expansion of the lithium battery is avoided, the internal strength is improved, and the problem that explosion is likely to be caused is avoided; and the safety of the lithium battery in the use process is effectively improved.

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
