A method for producing a sheet-like plate

摘要

There is disclosed a method for producing a sheet-like electric cell plate and an electrochemical cell produced by using the plate. The sheet-like electric cell plate is produced by a method which comprises discharging an electrode material coating solution from an extrusion-type slot die and coating the solution onto an electrically-conductive support running around a backup roll. The electrochemical cell comprises a positive electrode plate, a negative electrode plate, both of which plates are produced by the above method, and an electrolyte.
