Cause of failure(1) Gluing and punching;(2) Leakage phenomenon;(3) The transition rod of the adhesive tape is not flexible;Maintenance methods(1) Loosen the screws of the adhesive fixing plate and lift it up a bit during the feeding process, so that it touches the center of the battery cell as much...

Cause of failure(1) Whether the rolling needles are concentric;(2) The rolling needle is not perpendicular to the substrate;(3) The electrode guide plate is not perpendicular or parallel to the substrate;(4) The final transition roller of the polarizer is not perpendicular to the substrate;(5) The i...

1. Misalignment and Conicity of Separators in Cylindrical Lithium ion BatteriesReasons for misalignment and cone-shaped separators in cylindrical lithium-ion batteries:(1) Whether the rolling needles are concentric;(2) The rolling needle is not perpendicular to the substrate;(3) The last transition...

There are not many manufacturers internationally capable of mass producing lithium-ion titanate batteries. The important application markets for lithium-ion titanate batteries include electric vehicles (buses, rail transit, etc.), energy storage markets (frequency regulation, power grid quality, win...

Generally speaking, the lifespan of a lithium battery can be maintained for about 3 years, and well maintained batteries can last up to 5 years.The skeleton structure of lithium titanate material hardly shrinks or expands during the process of charge discharge insertion and extraction of lithium ion...

The service life of lithium titanate batteriesThe emergence of electric vehicles has invisibly solved the problem of severe urban environmental pollution. In order to meet the requirements of electric vehicles for batteries, developing batteries with high safety, good rate performance, multiple cycl...

3 Overcharging When the iron core is overcharged, the excessive release of lithium from the positive electrode will change the structure of the positive electrode. Excessive lithium can easily enter the negative electrode and cause lithium to precipitate on the surface of th...

In response to the thermal runaway of lithium-ion battery packs, the current mainstream solution in China is to improve from two aspects: external protection and internal improvement. External protection refers to the upgrading and improvement of the system, while internal improvement refers t...

Analysis of the causes of ignition in power lithium-ion battery packsThe most important reason for the ignition of lithium-ion battery packs is that the heat inside the battery cannot be released according to the design requirements, leading to ignition after reaching the ignition point of internal...

5. Lithium nickel cobalt manganese oxideLithium nickel cobalt manganese oxide is one of the key materials for lithium-ion batteries. Lithium cobalt oxide is currently the most widely used battery material, but cobalt resources are becoming increasingly scarce and expensive, and there are safety haza...
