Classification: CPC H  Y | IPC H

Claim 5:
6. A method comprising:
preparing an initial anode from anode material particles, and
coating only a part of the initial anode with a coating layer of an ionic-conductive polymer that provides an artificial SEI (solid-electrolyte interphase) to facilitate lithium ion transfer therethrough while preventing fluid communication with the anode material particles and prevents direct fluid electrolyte contact with the anode material particles; wherein the ionic-conductive polymer comprises thermoset polyimides;
wherein the coating of the only part of the initial anode comprises polymerizing the coating layer at least partially in situ, by applying monomer/oligomer material to the initial anode and initiating polymerization after the application of the monomer/oligomer material; wherein the polymerizing the coating layer at least partially in situ comprises only partially polymerizing the coating layer in situ.
