Abstract

An iron-based pyrophosphate compound, Na₂FeP₂O₇, is investigated as a positive electrode material for aqueous sodium-ion batteries for the first time. The high rate capability and good cyclability of this material in aqueous electrolytes are advantageous for low-cost and safe battery systems.
