Abstract
This invention is directed to lithium and lithium alloy metal substrates, coated with a polymeric layer containing dispersed lithium or lithium alloy metal particles. The coated metal finds use as anode material in solid electrochemical cells. A method of forming the same is disclosed.
Claims3
A method of making a lithium anode material for solid electrochemical cells comprising the steps of:
- dispersing particles of lithium or lithium alloy metal in a polymer precursor composition;
- coating a lithium or lithium alloy metal surface with said polymer precursor composition;
- and
- partially or totally curing said polymer precursor composition.
The method according to claim 6 wherein said curing is carried out by exposing said polymer precursor composition to ultraviolet light or an electron beam.
A method of making a lithium anode material for solid electrochemical cells comprises the steps of:
- dispersing particles of lithium or lithium alloy metal in a melt or solution of intrinsically conductive polymer to form a coating composition;
- coating a lithium or lithium alloy metal surface with said composition;
- and
- permitting said composition to form a solid polymeric layer on said lithium or lithium alloy metal surface.
