摘要： PROBLEM TO BE SOLVED: To prevent the dispersion of filling weight or filling density caused by intermittent coating, removing adverse effects on the back surface attendant on compulsory remove of an active material layer, and to enhance the characteristics or safety of battery in the manufacturing process of the battery. SOLUTION: A battery is manufactured by the use of an electrode having an active material layer 5 intermittently formed on a current collector 1. Slurry, containing an active material, a binder, and an organic solvent, is continuously applied on a current collector 1 to form an active material layer 5. For example, a solvent capable of dissolving or swelling the binder is applied or sprayed to the part, corresponding to the intermittent part of the active material layer 5 to form a non-soldified part 5a. The non-solidified part 5a is removed by peeling off with a sticky material, applying an ultrasonic wave, air jet or the like to form an intermittent part 15 in the active material layer 5.

摘要： PROBLEM TO BE SOLVED: To improve a service capacity and a cycle life by containing boron and oxygen at a specific ratio in a carbonaceous material contained in a nega tive electrode and storing/releasing lithium ions, and processing it with an alka line solution containing an alkali metal. SOLUTION: Boron of 0.1-5 wt.% is contained in a carbonaceous material such as a graphite structure preferably in a solid solution state, the deposition of lithium on the carbonaceous material is suppressed at the time of a rapid charge, graphite crystallinity is improved, and a service capacity is increased. Oxygen of 0.05-1 wt.% is contained, bonding with carbon is preferable, and the charge/discharge efficiency is increased by the improvement of the lithium ion storage/release potential of a negative electrode and the function of a protective film against a nonaqueous electrolyte. It is attained by the heat treatment of a graphitized carbon material and a boron oxide or a boron compound in the prescribed atmosphere. An alkaline solution treatment is preferably applied at 60 deg.C, alkali metal ions are stably fixed on the surface of the carbonaceous material, and a reversible storage/release site of lithium ions is formed.
