Abstract

A method of stabilizing lithium metal powder is provided. The method includes the steps of heating lithium metal to a temperature above its melting point, agitating the molten lithium metal, and contacting the lithium metal with a fluorination agent to provide a stabilized lithium metal powder.

Claims

exact text as granted — not AI-modified

1 . A method of stabilizing lithium metal powder comprising the steps of:
 a) heating lithium metal to a temperature above its melting point;   b) agitating the molten lithium metal; and   c) contacting the lithium metal with a fluorination agent to provide a stabilized lithium metal powder.   
     
     
         2 . The method of  claim 1 , wherein step (a) is done in a hydrocarbon oil. 
     
     
         3 . The method of  claim 2 , wherein the stabilized lithium metal powder is subjected to treatment to remove residual hydrocarbon oil. 
     
     
         4 . The method of  claim 1 , wherein the lithium metal powder has a median particle size of 10 to 500 microns. 
     
     
         5 . The method of  claim 1  wherein the molten lithium metal is cooled to a temperature of 24° C. to 200° C.
