Abstract: 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.

Abstract: A gel electrolyte secondary cell includes a positive electrode, a negative electrode and a gel electrolyte. The negative electrode includes a current collector, and a mixture of powders of a graphite carbonaceous material and a binder. The powders of the graphite carbonaceous material include sintered meso-carbon micro-beads. The gel electrolyte includes an electrolyte salt, a non-aqueous solvent and a high-molecular weight material. The non-aqueous solvent includes propylene carbonate and ethylene carbonate. A content of propylene carbonate ranges from 35 mol % to 75 mol %. The binder is in an amount 1 to 20 wt % based on total weight of the powders of the graphite carbonaceous material. The meso-carbon micro-beads can suitably decrease the impedance and the discharge capacity loss, thereby increasing the discharging capacity and/or charging/discharging efficiency of the gel electrolyte secondary cell.
