Furthermore, they tend to spontaneously react with most polar aprotic electrolyte solvents, salt anions, and dissolved cathode materials, leading to undesired cycle performance issues in currently available battery types. In alkali metal-S batteries, the “shuttle effect” derived from polysulfides ...
Young-Jun Kim1 & Hun-Joon Sohn6 Sodium rechargeable batteries can be excellent alternatives to replace lithium rechargeable ones because of the high abundance and low cost of sodium; however, there is a need to further improve the battery performance, cost-effectiveness, and safety for practi...
(de)intercalation, the small size not only facilitates a fast diffusion kinetics, but also reduces structure strain leading to a long cycle life. The lightweighted protons can decrease the mass of entire battery systems and induce a higher theoretical capacity when comparing with traditional metallic...
