Abstract

An aspect of the present invention is an electrode which includes an active material layer, and an insulating layer layered on a surface of the active material layer, in which the insulating layer contains a filler and a first binder, and a content of the first binder in the insulating layer is 8% by mass or more. Another aspect of the present invention is an electrode which includes an active material layer, and an insulating layer layered on a surface of the active material layer, in which the insulating layer is a dry coating product containing a filler and a binder. Still another aspect of the present invention is a method for manufacturing an electrode, which includes the steps of forming an active material layer, and laminating an insulator containing a filler and a binder on a surface of the active material layer to form an insulating layer, in which the insulator does not contain a solvent.

Claims

exact text as granted — not AI-modified
1 - 17 . (canceled) 
     
     
         18 . A method for manufacturing an electrode, comprising:
 forming a positive active material layer; and   laminating an insulator containing a filler and a binder on a surface of the positive active material layer to form an insulating layer,   wherein the insulator does not contain a solvent.   
     
     
         19 - 20 . (canceled) 
     
     
         21 . The method according to  claim 18 , further comprising heating the insulator. 
     
     
         22 . The method according to  claim 18 , wherein the filler is inorganic particles and the binder is a thermoplastic resin. 
     
     
         23 . The method according to  claim 22 , further comprising heating the insulator to fuse the thermoplastic resin together. 
     
     
         24 . A method for manufacturing an electrode, comprising:
 forming a positive active material layer, and   coating an insulator in a dry powder state containing a filler and a binder on a surface of the positive active material layer to form an insulating layer.   
     
     
         25 . The method according to  claim 24 , further comprising heating the insulator. 
     
     
         26 . The method according to  claim 24 , wherein the filler is inorganic particles and the binder is a thermoplastic resin. 
     
     
         27 . The method according to  claim 26 , further comprising heating the insulator to fuse the thermoplastic resin together. 
     
     
         28 . A method for manufacturing an electrode, comprising:
 forming a positive active material layer, and   forming an insulating layer by dry coating on a surface of the positive active material layer.
