Bio-inspired battery design: Research uses electrolyte methylation to improve flexible sodium-ion batteries

Flexible aqueous batteries, such as those used in portable electronics, often contain a hydrogel electrolyte containing water and salt. Using a chemical modification inspired by nature, a team of Chinese researchers have now significantly increased the salt stability of hydrogels used in sodium-ion batteries. A simple methylation of the hydrogel's structural polymer prevented salting-out and improved battery capacity and cycling performance, the team report in the journal Angewandte Chemie International Edition.
