Turning once-troublesome protons into an energy storage resource for batteries

A research team led by Sarah S. Park from the Department of Chemistry (KAIST) has developed a new electrode material that sequentially stores zinc ions (Zn²⁺) and protons in aqueous batteries. The material is based on a two-dimensional conductive metal-organic framework (MOF), a structure in which metals and organic molecules are connected to form microscopic pores.
