Multifunctional role of gallium-doping in O3-type layered-oxide cathodes for sodium-ion batteries: Enhancing bulk-to-surface stability
{{output}}
Charging O3-type layered-oxide cathodes to a high cutoff voltage of 4.3 V (vs. Na+/Na) can enhance the energy density of sodium-ion batteries (SIBs). However, the irreversible oxygen redox reaction at high voltages often leads accelerated capacity degradation.... ...
