Abstract

In a non-aqueous electrolyte battery provided with a positive electrode, a negative electrode, and a non-aqueous electrolyte using an organic solvent, at least one type of ferrite, FeS 2 , and a transition metal oxide (except for LiCoO 2 ) having crystal structure of space group R3m is used as a positive electrode material for a positive electrode, and a negative electrode material containing lithium is used for a negative electrode.

Claims

exact text as granted — not AI-modified

What is claimed is:  
     
         1 . A non-aqueous electrolyte battery provided with a positive electrode, a negative electrode, and a non-aqueous electrolyte using an organic electrolyte, wherein 
 a positive electrode material containing at least FeS 2  is used for said positive electrode, and a lithium alloy is used as a negative electrode material for said negative electrode.    
     
     
         2 . The non-aqueous electrolyte battery according to  claim 1 , wherein 
 the negative electrode material for said negative electrode is a lithium alloy (Li—Si).    
     
     
         3 . The non-aqueous electrolyte battery according to  claim 1  is a secondary battery wherein discharge/charge is repeatedly performed.
