P2-type manganese-based layered oxides are regarded as promising cathode material for sodium-ion batteries. However, irreversible interfacial reactions occurring on non-sodium-containing anode will markedly consume active Na+ ions in oxides, leading to rapid capacity decay full cell. Herein, a highly efficient sodium compensation additive, formate (HCOONa), is proposed. The results show that the cell based Na0.66Ni0.26Zn0.07Mn0.67O2 (NNZMO) and hard carbon with HCOONa additive can provide 95.7 mAh g–1 first-cycle discharge specific 81.3% retention after 100 cycles at mA g–1, much higher than those (71.8 55.7%) of NNZMO without formate. This strategy provides new way increasing operation stability also expected be applicable other materials.

Sodium-ion batteries (SIBs) are advantageous for large-scale energy storage due to the plentiful and ubiquitous nature of sodium resources, coupled with their lower cost relative alternative technologies. To expedite market adoption SIBs, enhancing density SIBs is essential. Raising operational voltage cathode regarded as an effective strategy achieving this goal, but it requires stable high-voltage materials. Sodium iron sulfate (NFSO) considered be a promising material its framework, adjustable structure, safety, high electronegativity SO
