Abstract
The present invention relates to a method for production of electrodes for Li-primary and Li-ion batteries based of using two types of binder. The first binder is soluble in organic solvent and second binder is insoluble in organic solvent during the process of slurry preparation. Combination of the slurry composition and conditions of the electrode temperature treatment decrease the cathode production complexity, improve electrochemical characteristics of the electrode, increase adhesion properties and flexibility of coating, and reduce the interface resistance between the current collector and electrode mass.
