Controllable preparation of cation vacancy-modulated oxygen defects Mn2-xP2O7-y anodes to enhance the lithium storage performance

Oxygen-deficient Mn2-xP2O7-y with modulated cation vacancies were synthesized using a solvothermal method, through the synergistic influence of the these vacancies, the optimized manganese pyrophosphate anode (Mn1.93P2O7-y) exhibits enhanced electrochemical properties.
