Abstract
An electrode plate in which electrode active material powder and an electrode mixture layer mainly composed of a thermoplastic binder are held on a conductive substrate is crushed. Then, the crushed materials are mixed with organic solvent so that a coating material made of the crushed electrode is prepared. The coating material made of the crushed electrode is applied to the surface of the conductive substrate so that an electrode is manufactured. As an alternative to this, an electrode mixture coating material made of electrode active material powder, thermoplastic resin and organic solvent is dried so that a solid electrode is obtained. Crushed materials obtained by crushing the solid electrode are mixed with organic solvent so that a coating material made of the crushed electrode is prepared. The coating material made of the crushed electrode is applied to the conductive substrate so that an electrode is manufactured. The manufacturing methods enable an electrode having excellent characteristics to be manufactured with a low cost by reusing a waste coating material generated because of a process for manufacturing electrodes or scraps of electrodes or electrodes included in spent batteries.
