Elucidating the stabilizing effect of copper substitution in high voltage P2-type layered oxides for sodium ion batteries

Key Points

Investigate how copper substitution can improve the stability of P2-type layered sodium transition-metal oxides in high-voltage sodium-ion batteries.
Analyzed structural characteristics of P2-type layered oxides before and after copper substitution
Tested electrochemical performance in varying voltage conditions
Measured capacity retention over multiple charge-discharge cycles
Copper substitution significantly improved structural stability under high-voltage conditions
Enhanced capacity retention observed during cycling tests
Reduction in irreversible redox reactions was noted with copper-enriched materials

Abstract

P2-type layered sodium transition-metal oxides are promising high-energy cathodes for sodium-ion batteries but suffer from structural degradation and irreversible redox reaction particularly in the high-voltage region, resulting in rapid capacity...
