PURPOSE:To manufacture a lithium secondary battery negative electrode body of graphite type which exert excellent charging/discharging performance through combining with an electrolyte particularly containing ethylene carbonate. CONSTITUTION:A film-form molding of 200mum thick or less made from aromatic polyimide is baked and turned into graphite at a temp, over 2300 deg.C in a non- oxidative atmosphere. The graphite film obtained is used as it is as the body of negative electrode or fine crushed into the mean particle size 100mum followed by molding together with components of organic binder material to yield a body of negative electrode. |
