CATL applies for new battery patent

Recently, new patent applications for CATL batteries have been filed, such as patents for "end cover components, battery cells, batteries and electrical devices". This patent can reduce the risk of corrosion of the pressure relief mechanism and improve safety. For example, patents for "casing, battery cells, batteries and electrical equipment"; patents for "end covers, battery cells, batteries and electrical equipment" will not cause stress concentration in the wire harness and reduce the possibility of damage to the wire harness. For example, the patent for "battery cells, batteries and electrical devices" can reduce the occurrence of the cover being suspended, thereby reducing the negative impact of welding marks on the cover, allowing the cover to be better bonded to the adapter, easing the Solved the problem of loose and falling cover parts. For example, "battery self-discharge detection methods, devices, equipment and storage media" can improve the convenience and efficiency of battery self-discharge detection. For example, the patent for "battery cells, batteries and electrical devices" can reduce the impact of the high temperature generated during welding of the pole body on the first welding part and improve the reliability of the battery cells.

At the same time, we see that CATL continues to make efforts in the field of supercharged batteries. CATL recently revealed on an interactive platform that Shenxing supercharged battery is the world’s first 4C supercharged battery that uses lithium iron phosphate material and can achieve mass production. Battery. At present, it has confirmed cooperation with many car companies such as GAC, Chery, Avita, Nezha, Jihu, and Lantu. It is expected to be installed on trucks in the first half of 2024.

It is reported that Ningde era’s “Shenxing super-chargeable battery” can replenish 400 kilometers of battery life after charging for 10 minutes. CATL's "Shenxing Superchargeable Battery" is equipped with ultra-electronic network cathode technology, graphite fast ion ring anode technology, ultra-thin SEI membrane, ultra-high conductivity electrolyte formula, and high-porosity isolation membrane, with a total battery life of up to 700 kilometers.
