GEL ELECTRODE SECONDARY CELL

摘要

A gel electrolyte secondary cell in which discharge capacity loss can be suppressed even with the use of a graphitized carbonaceous material of a small particle size as a negative electrode material to assure low impedance, superior cell voltage and load characteristics and high charging/discharging efficiency. To this end, a graphitized carbonaceous material prepared by firing meso-carbon micro-beads is used as a material for a negative electrode.
