Considering the abundance of iron and manganese within Earth's crust, cathode O3-NaFe0.5Mn0.5O2 has shown great potential for large-scale energy storage. Following strategy introducing specific heteroelements to optimize structural stability storage, work obtained an O3-type NaFe0.4Mn0.49Cu0.1Zr0.01O2 that exhibits enhanced electrochemical performance air stability. It displays initial reversible capacity 147.5 mAh g–1 at 0.1C between 2 4.1 V, a retention ratio exceeding 69.6% after 100...
Ammonium phosphate ((NH4)3PO4) has been first used as a surface treatment reagent for Li-rich cathode materials. Compared to the conventional treatment, samples treated with (NH4)3PO4 exhibit an ultra-high initial Coulomb efficiency of 98.0% and excellent cycling stability. This is mainly attributed simultaneous construction integrated structures, including oxygen vacancies, spinel phases, Li3PO4 coating. study demonstrates effectiveness ammonium provides new idea designing other
Sodium-ion batteries (SIBs) provide an attractive option for large-scale electrochemical energy storage applications. However, the approach to realize highly reversible cathode materials needs further exploration. Our work adopts a universal nonaqueous solution process in coating functional Al-PO4 layer on material Na0.44MnO2 (NMO) SIBs. Surface modification of NMO by AlPO4 facilitates interfacial charge transfer reactions and enhances pseudocapacitance's contribution. The optimized 0.5 wt%...
