Abstract: PROBLEM TO BE SOLVED: To reduce the cost and battery resistance, by containing a polymer binder composed of a monomer containing no fluorine, and a solid capable of reversibly catching or releasing a lithium ion in electrochemical reaction. SOLUTION: A graphite of 90g is stirringly added into the solution of a polyacrylic resin A of 1.84g in a tetrahydropyran of 75.13g, in a the tetrahydropyran of 75.13g, to perform stirring for 10 minutes. The resin A is copolymer composed of a 2-ethylhexyl acrylate of 95wt.%, and a monobutyl maleylate of 2wt.%, and is containing a cross linking agent of 2.5wt.%. The stirred dispersion liquid is moreover stirred for two hours by a roller stand, and then is applied a thin copper plate with a knife coater, to be dried and a resultant layer is dried at room temperature for 10 minutes, and moreover at 100 deg.C for 10 minutes. This can obtain an electrode capable of showing an excellent mechanical characteristic and also an excellent electrochemical characteristic to a lithium metallic plate, and reducing battery resistance, showing an excellent mechanical, at a low cost.
