Abstract: PROBLEM TO BE SOLVED: To suppress the generation of an electrode surface defects by mixing and dissolving or dispersing a binder to a solvent, and then adding an active material and a conductive agent thereto followed by kneading. SOLUTION: By dissolving a binder to a solvent first, the mass of an active material or conductive agent entangled to the undissolved binder is eliminated, whereby a stripe or surface defect resulted from the mass can be eliminated in the application of a slurry. When the conductive agent and the active material are added to the binder solution followed by kneading, the powder having the larger surface area is preferably added first. Because the one having the larger surface area has a poor kneading efficiency, and a slurry having a more satisfactory dispersed state can be provided by performing the kneading in the state having a low slurry viscosity. The kneading is preferably performed under a reduced pressure, in order to prevent the entanglement of an atmospheric gas, such as air in the slurry from the viewpoint of the prevention of an electrode surface defects such as void after application. However, when the pressure reduction can not be performed with kneading in relation to a device, the slurry may be taken out after the kneading is ended and degassed under reduced pressure.

Abstract: PROBLEM TO BE SOLVED: To enable the manufacture of a battery having a high capacity, high output characteristic, excellent cycle characteristic and high safety at a low cost by coating an electrode board with the film forming solution, and thereafter, making the coating solution contact the lean solvent of the film forming material so as to manufacture an electrode for the battery. SOLUTION: At the time of manufacturing an electrode, the film forming material at several wt.%-20wt.% is dissolved in the rich solvent, and an electrode board is dipped with the solvent so as to form a coating film. The electrode board formed with the coating film is dipped with the lean solvent such as water, methanol, ethanol acetone, hexane, and the rich solvent in the coating film provided on the electrode board is replaced with the lean solvent, and the film forming material is deposited so as to form the coating film 3, which is provided on the electrode board, into a fine porous film. Thereafter, the film is heated for drying.

Abstract: PROBLEM TO BE SOLVED: To reduce or prevent the breakage or firing of a battery even when a physical impact is added to a battery can in charging sate by peeling a current collector from an electrode when an electrolyte is raised to a specified temperature range. SOLUTION: A nonaqueous electrolyte secondary battery is constituted in such a manner that a positive electrode and a negative electrode are at least partially peeled from a current collector within an electrolyte temperature range of 60-120 deg.C. For this, a binder such as fluorine-contained resin is contained in the positive electrode and the negative electrode in an amount of about 0.5-10wt.%, and when the electrolyte is raised to 60 deg.C or more, the current collector is peeled from the electrode bodies. As a peeling accelerator, an inorganic or organic foaming agent is contained in the battery. The foaming agent generates a gas at an electrolyte temperature of 60 deg.C or more to peel the electrode materials from the current collector. Thus, since the flow of electron or ion is arrested to make the current hard to flow, the rise of internal pressure by boiling of the electrolyte or thermal runaway of an active material can be suppressed.
