IMPACT OF SUBSTRATE SURFACE PREPARATION METHOD ON SEI FORMATION REGULARITIES DURING ELECTROCHEMICAL DEPOSITION OF LITHIUM

Abstract

The use of lithium metal as an anode for batteries has undeniable advantages because this metal has the most negative reduction potential and the highest theoretical specific capacity. The reduction of lithium metal initially involves processes of solution components decomposition with the formation of SEI - a film of interfacial electrolyte, under which lithium is further deposited. Reversible lithium deposition requires it to have pure ionic conductivity and high mechanical strength.
