1. A method of preparing an anode for an electrochemical cell comprising the steps of:
- providing a lithium anode element having an operative surface area to be associated with a cathode;
contacting at least the operative surface area of the anode element with organic material, andheating the anode element and organic material together to a temperature between at least about 260°
F. and the melting temperature of the organic material.

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.
