A Halogen‐Free and Flame‐Retardant Sodium Electrolyte Compatible with Hard Carbon Anodes (Adv. Mater. Interfaces 23/2021)

Halogen-Free and Flame-Retardant Electrolyte for Sodium-ion Batteries Apart from achieving a greater understanding of fluorine-free electrolytes, it is essential to create safer electrolytes the state-of-the-art sodium-ion batteries. In article number 2101135, Lars Olow Simon Colbin, Reza Younesi, co-workers demonstrate that using triethyl phosphate (TEP) with sodium bis(oxalato)borate (NaBOB) as electrolyte will help achieve this goal. Imagine if battery could also fight fires, rather than fueling them—the case today.
