    摘要: The present invention uses a mixture of spherical carbonaceous materials having different average particle sizes as an anode active material in an anode composite mixture layer of an anode. The spherical carbonaceous material of large particle size decreases the reaction with non-aqueous electrolyte solution to suppress the decrease in battery capacity, form clearances having suitable sizes in the anode composite mixture layer, and retain the non-aqueous electrolyte solution. The clearances in the anode composite mixture layer are efficiently filled with the carbonaceous material of small particle size while spaces capable of suitably retaining the non-aqueous electrolyte solution are left unfilled. Thus, the volume density of the anode composite mixture layer is improved and the battery capacity is increased. Accordingly, energy density can be increased without deteriorating battery characteristics.
