This paper exposes the enhanced surface properties of separator and foil components of lithium ion batteries using atmospheric plasma technology. Specifically addressed is the creation of high‐performance and costeffective surface characteristics of foils and separators using in‐line, continuous atmospheric plasma technology for practical applications in lithium‐ion polymer batteries.
The modified separator membranes utilizing the atmospheric plasma modification process showed significantly improved wettability and electrolyte retention. Plasma treatment of foils leads to high surface tension and cleaning of surface contaminations to improve interfacial adhesion with coatings.
