NOVELTY - An active material, carbon black as electroconductive agent, a binder, and a dispersion medium are kneaded to obtain a viscous solution. The viscous solution is coated on a collector surface and dried to obtain an anode plate (5). The active material is lithium-containing complex oxide having an average particle diameter of 5-20 microns and a specific surface area of 0.2-2 m2/g. Thus, a non-aqueous-electrolyte secondary battery using lithium-containing complex oxide as anode active material, is obtained.    USE - For manufacturing non-aqueous-electrolyte secondary batteries useful as power supply for portable electronic devices.    ADVANTAGE - The method provides lightweight and compact non-aqueous-electrolyte secondary batteries having high capacitance and energy density and excellent cycle characteristics.    DETAILED DESCRIPTION - An active material, carbon black as electroconductive agent, a binder, and a dispersion medium are kneaded to obtain a viscous solution. The viscous solution is coated on a collector surface and dried to obtain an anode plate (5). The active material is lithium-containing complex oxide having an average particle diameter of 5-20 microns and a specific surface area of 0.2-2 m2/g. Thus, a non-aqueous-electrolyte secondary battery using lithium-containing complex oxide as anode active material, is obtained. The dibutyl phthalate absorbed quantity of the active material is carried out as follows by JIS K-6217-4. The titration of the reagent-solution component is carried out with a constant-speed degree burette. Change of viscosity characteristics is measured and recorded with a torque detector. The liquid adsorption when making the additional amount of the reagent-solution component corresponding to the torque into a liquid adsorption 70% of the produced maximum torque is less than 20 ml/100 g. The content of electroconductive agent is 0.5-5 wt.% and the content of binder is 1-10 wt.%, with respect to 100 wt.% of anode active material.
