secondary battery

Abstract

Abstract PURPOSE:To increase the volume efficiency of a battery, to make the reversibility, the charge-discharge performance, and the reliability excellent, and to lengthen the life by using a molding mainly comprising carbon powder having a specific lattice spacing in a negative electrode. CONSTITUTION:A composite obtained by adsorbing lithium in a molding of carbon powder having a lattice spacing of 3.38-3.56Angstrom in X-ray diffraction is used in a negative electrode 3. A mean particle size of the carbon powder used for the molding is 0.1-30mum. The carbon powder is prepared by crushing carbon fiber, carbon block, or artificial graphite and classify the powder. The carbon powder is molded with binder in desired shape such as plate and sheet to form the negative electrode 3.
