New electrolyte design improves solid-state battery conductivity by 2.7 times

South Korean researchers unveiled an oxygen-anchoring electrolyte design for halide-based solid-state batteries.

By using tungsten, the approach improves moisture resistance and lithium-ion transport, boosting ionic conductivity 2.7 times.

The method works across multiple material systems, suggesting a more universal path to stable halide electrolytes.

If scalable, the design could help make solid-state batteries safer, easier to manufacture, and faster-charging for EVs.
