Problems solved by technology
The traditional manufacturing method of the lithium sub-power battery cathode is to put the mixed powder into the roller machine and roll it several times to form a diaphragm. After the diaphragm is dried, it is pasted together with a special adhesive. This method There are great disadvantages: first, repeated rolling damages the physical properties of each material, and second, poor adhesion of the adhesive will affect the internal resistance of the battery, and the adhesive is mostly organic, which will react with the electrolyte, and the final rate performance decline
