Anion-cation interactions dictate safe and stable electrolytes for sodium-ion batteries
Abstract
Sodium-ion battery safety can be improved by using non-flammable electrolytes, but they are traditionally incompatible with carbon-based anodes. Now, low-concentration phosphate electrolytes modulated by anion-cation interactions are shown to work well with standard electrodes, displaying stable operation over a wide temperature range.
