Abstract
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 lithium conductive material, and a reinforcing additive. Optionally, an interface coating may reside on one or more sides of the separator to ensure long-term operation. By utilizing such a separator in a solid-state lithium battery, cell assembly may be simplified, shrinkage may be decreased and safety may be increased. Various methods of manufacturing the solid-state polymer separator for lithium-ion batteries are disclosed.
