SECONDARY BATTERY-USE ELECTRODE AND PRODUCTION METHOD THEREFOR AND SECONDARY BATTERY

摘要

An electrode used as an anode or a cathode for a secondary battery. The electrode is in contact with an electrolyte, includes a pair of front and rear surfaces having conductivity, and is provided between the surfaces thereof with an active material layer including active material particles. It further has many fine pores opened in the surfaces and communicating with the active material layer. A current collecting surface layer preferably has a thickness of 0.3-20 mum. The active material layer is preferably formed by coating conductive slurry containing active material particles. The current collecting surface layer is preferably formed by electro-plating.
