Method of manufacturing electrode for electrochemical device

Abstract

A method of manufacturing an electrode for an electrochemical device is provided with the steps of: supplying, onto a collector, a powdered mixture containing a binder and an active material; and heating the powdered mixture to form an electrode layer on the collector, that allows continuous mass production of electrodes for electrochemical devices.

1 . A method of manufacturing an electrode for an electrochemical device, comprising the steps of: 
 supplying, onto a collector, a powdered mixture containing a binder and an active material; and    heating the powdered mixture to form an electrode layer on the collector.    
   
   
       2 . The method according to  claim 1 , wherein the electrochemical device is an electric double layer capacitor, and the active material is a carbonaceous material.  
   
   
       3 . The method according to  claim 1 , wherein the powdered mixture further contains an electroconductivity-imparting agent.  
   
   
       4 . The method according to  claim 2 , wherein 100 parts by weight of the powdered mixture contains 0.1 to 50 parts by weight of the binder and 50 to 99.9 parts by weight of a carbonaceous material for use as the active material and the electroconductivity-imparting agent.  
   
   
       5 . The method according to  claim 1 , wherein the binder contains at least one of particulate rubber and particulate thermoplastic elastomer.  
   
   
       6 . The method according to  claim 1 , wherein the binder contains particulate rubber and particulate thermoplastic elastomer.  
   
   
       7 . The method according to  claim 5 , wherein the thermoplastic elastomer is a graft polymer of an ethylene/acrylic (or methacrylic) ester copolymer graft polymerized radical-polymerizable monomer thereon.  
   
   
       8 . The method according to  claim 1 , wherein the binder has a particle diameter of 0.01 to 10 μm.  
   
   
       9 . The method according to  claim 1 , further comprising the step of press-forming the powdered mixture under heating or after heating.
