ALEXANDRIA, Va., March 26 -- United States Patent no. 12,261,321, issued on March 25, was assigned to Piersica Inc. (Sunrise, Fla.).

"Solid-state polymer separator for lithium-ion batteries" was invented by Claudiu B. Bucur (Sunrise, Fla.).

According to the abstract* released by the U.S. Patent & Trademark Office: "A safe, thin and highly conductive solid-state polymer separator for lithium-ion batteries. The separator may be deployed in a battery which lacks solvent and allows lithium ions to pass through channels via the polymerized structure. The lithium conductive polymers may be formed through free radical polymerization and may comprise a lithium conductive polymer having a polymerized carbonate solvent between iterative spacers, a ...
