A team from the Massachusetts Institute of Technology recently published a paper in the journal *Joule*, announcing the successful development of a new solvent, DMTMSA, which effectively addresses the challenges of stability and fast charging in sodium metal batteries. The research was led by Professor Li Zhu, aiming to use sodium, which is 1,000 times richer in lithium and cheaper in cost, as an energy storage solution. It was found that this sulfonamide molecule remains stable in both lithium and sodium batteries, and by selecting solvents with smaller sizes, ion transport was accelerated, thereby achieving both long cycle life and fast charging and discharging capabilities.
