Article Synopsis
- Alkali metal salts typically have high melting points due to strong electrostatic forces, necessitating solvents for liquid electrolytes at room temperature.
- The study discusses six room-temperature liquid phosphate-anion-based alkali metal salts (Li/Na/K) that are thermally stable up to 225 °C and have glass transition temperatures from -61 to -29 °C.
- These salts show high anodic stabilities (up to 6 V) and some battery performance at elevated temperatures, suggesting that solvent-free electrolyte designs may lead to innovative battery concepts despite current performance limitations.
Single-ion conducting polymer electrolytes created by plasticizing LiPSTFSI with PPO and LiTFSI are shown to both improve the ionic conductivity and alter the ion conduction mechanism. This correlates with both local and macroscopic properties, opening for rational design of solid-state, but yet pliable electrolytes.

The access of their entire potential requires a comprehensive understanding of their electrochemical mechanism. This Review highlights the processes taking place during the alloying reaction of Si and Ge with the alkali ions.
