Abstract

A lithium ion secondary battery comprises a non-aqueous electrolytic solution, and a current collector which is coated with an active material and immersed in the electrolytic solution. By setting the coating thickness of said active material 5-80 μm, the power density of the lithium ion secondary battery is improved.

Claims

exact text as granted — not AI-modified
What is claimed:  
     
         1 . A lithium ion secondary battery comprising: 
 a non-aqueous electrolytic solution, and    a current collector which is coated with an active material and immersed in said electrolytic solution,    wherein the coating thickness of said active material is 5-80 μm.    
     
     
         2 . A lithium ion secondary battery as defined in    claim 1   , wherein the coating thickness of said active material is 8-60 μm.  
     
     
         3 . A lithium ion secondary battery as defined in    claim 1   , wherein the particle size of said active material is smaller than 5 μm.
