A new solid polymer electrolyte may improve lithium-metal batteries across wide temperatures and high voltage.

Researchers developed a solid polymer electrolyte using an in-situ polymerization process to address the tradeoff between ionic conductivity and high-voltage stability. The reported material enables lithium-metal batteries to operate from -40°C to 55°C and maintain stable cycling at 4.5V. The work suggests automotive potential, though commercial readiness, long-term durability, cost, and scale-up details were not established in the provided source.
