CATL applies for multiple sodium-ion battery patents to promote the industrialization of sodium-ion batteries

Recently, the State Intellectual Property Office announced several sodium-ion battery patent applications from CATL. These patents include "sodium-ion batteries, battery modules, battery packs and power-using devices", "sodium-ion battery monomers and their preparation methods, and related devices", "sodium-ion battery positive electrode materials and their preparation methods, positive electrode sheets, batteries and power-using devices". If the application is successful, these patents may be applied to CATL's second-generation sodium-ion batteries.
