“Electronic Sponge” Strategy Enables Polyether Electrolytes for High-Voltage and Fast-Charging Quasi-Solid-State Batteries
Polyether electrolytes are promising for lithium (Li) metal batteries yet suffer from insufficient Li+ conductivity, low oxidative thresholds, and unstable electrolyte–electrode interphases under high-voltage and fast-charging conditions. Herein, inspired by a natural sponge’s water absorption and release, we develop...
