PRODUCTION OF SHEET ELECTRODE

摘要

PROBLEM TO BE SOLVED: To provide a production of a sheet electrode formed with an electrode active material so as not to leave an uncoated part on a collector surface to obtain a battery having an excellent energy volume density in a simple and easy way. SOLUTION: This method is to produce a sheet electrode by a reverse roll method of transferring an active material paste to a metal foil-made collector 10 with a coating roll 22 while supporting and conveying the collector 10 with a backup roll 23, and applying an active material 13 continuously on a surface of the collector 10. The production comprises the process of: supplying the active material paste on a surface of the coating roll 22; adjusting the width of the paste supplied on a surface of the coating roll 22 to equalize to the width of the collector 10 by removing the paste on a part exceeding the width of the collector 10 using a paste removing means 26 provided on the coating roll 22; and transfer-coating the active material paste thus adjusted in its width on the collector 10 by the coating roll 22.
