Abstract

A method of forming an electrode active material by reacting a metal fluoride and a reactant. The method includes a coating step and a comparatively low temperature annealing step. Also included is the electrode formed following the method.

Claims

exact text as granted — not AI-modified
We claim: 
     
         1 . A method of making an electrode, comprising:
 coating particles, wherein each particle includes a metal fluoride material, with a coating precursor material, wherein the coating precursor material includes a transition metal;   annealing the particles such that at least a portion of the metal fluoride material and at least a portion of the transition metal react to undergo a phase change; and   forming the coated particles into an electrode.   
     
     
         2 . The method of  claim 1 , wherein the electrode forming step comprises preparing a formulation composition of coated particles, binder, and conductive additive. 
     
     
         3 . The method of  claim 1 , wherein the metal fluoride material comprises copper fluoride. 
     
     
         4 . The method of  claim 1 , wherein the coating step comprising milling the particles with the coating precursor material. 
     
     
         5 . The method of  claim 4 , wherein the coating precursor material comprises a organo-metal complex. 
     
     
         6 . The method of  claim 4 , wherein the coating precursor material comprises a metal oxide. 
     
     
         7 . The method of  claim 4 , wherein the coating precursor material comprises elemental metal. 
     
     
         8 . The method of  claim 4 , wherein the coating precursor material comprises NiO. 
     
     
         9 . The method of  claim 4 , wherein the coating precursor material comprises TiO 2 . 
     
     
         10 . The method of  claim 4 , wherein the coating precursor material is Ni. 
     
     
         11 . The method of  claim 4 , wherein the coating precursor material comprises nickel (II) acetylacetonate. 
     
     
         12 . The method of  claim 4 , wherein the coating precursor material comprises nickel acetate. 
     
     
         13 . The method of  claim 1 , wherein the coating step comprises a solution coating process. 
     
     
         14 . The method of  claim 13 , wherein the coating precursor material comprises an organo-metal complex. 
     
     
         15 . The method of  claim 13 , wherein the coating precursor material comprises nickel (II) acetylacetonate. 
     
     
         16 . The method of  claim 1 , wherein the coating step comprises a physical vapor deposition process. 
     
     
         17 . The method of  claim 16 , wherein the coating precursor material comprises a metal oxide. 
     
     
         18 . The method of  claim 16 , wherein the coating precursor material comprises a metal nitride. 
     
     
         19 . The method of  claim 16 , wherein the coating precursor material comprises a metal silicate. 
     
     
         20 . The method of  claim 16 , wherein the coating precursor material is Ni or Ti.
