Latest Patents

One of his latest patents is a method for producing an electrode sheet. This method involves heating the electrode sheet before pressing to soften or melt binder particles contained in the electrode mixture layer. The process includes roll-pressing the heated electrode sheet using first and second rolls, where the temperature of the first roll is set lower than that of the second roll. This technique reduces the adhesive strength of binder particles to the first roll, allowing for better adhesion to the current collecting foil. Another patent details a method for producing an electrode sheet that includes roll-pressing an uncompressed electrode sheet with a current collecting foil and an uncompressed electrode layer. The method ensures that active material particles bond effectively to each other and to the current collecting foil.
