Abstract
Method of preparing lithium anodes contacted with organic materials prior to association of the anode with a cathode material wherein the contacted anode is first subjected to a heat treatment. Upon incorporation of the improved anode into an electrochemical battery or cell and association of the heat treated anode with a suitable cathode material, the cell may be discharged under controlled conditions for a short time prior to its usual 'burn-in' discharge.
