摘要： A sodium ion battery comprises a cathode having a porous redox active metal-organic framework material. The battery can be an organic electrolyte sodium ion battery wherein the electrolyte comprises a sodium salt dissolved in an organic solvent or mixture of organic solvents. Alternatively, the battery can comprise an aqueous sodium ion battery wherein the electrolyte comprises a sodium salt dissolved in an aqueous solvent. Battery performance is especially related to electrolyte and binder selection.
