Scandium doping, coating improve cycling stability of sodium-ion battery cathodes
Researchers have compared bulk scandium doping and surface scandium coating in O3-Na[Ni₁/₂Mn₁/₂]O₂ cathodes for sodium-ion batteries. Both approaches improved cycling stability, with the coated full cell retaining 91.2% of its initial capacity after 300 cycles, while structural analyses revealed distinct bulk- and surface-stabilization mechanisms.
