The objective of this program is to investigate methods for producing highly porous lithium electrodes for use in rechargeable spacecraft batteries. Initial goals were to experimentally achieve two performance curves that were selected from the open literature as laboratory bench marks. The report describes lithium polarization performances which meet one goal, and shows efficiencies of utilization of electrodeposited lithium which meet the second goal. Also included is a section showing the results of mathematical analyses of improved electrode structures. Such structures will be evaluated by comparison with the bench mark data to ascertain improvements in adhesion, in polarization, or in efficiency of utilization of active materials. Work is continuing toward improving the adhesion of active materials at the lithium electrode during charge-discharge cycling. Also included are technical details on procedures for the use of a silver-silver chloride reference electrode, and for establishing ohmic resistance corrections for working lithium electrodes. The electrolytic cell and associated component parts are described in a separate section on Technical Detail. Author
