Inhibition of the P3–O3 phase transition <i>via</i> local symmetry tuning in P3-type layered cathodes for ultra-stable sodium storage

Abstract

We reconfigure the sodiation/desodiation process of P3-type layered cathodes by a local symmetry tuning strategy to enhance their stability. The cathodes exhibit long-term cycling stability with a higher capacity retention of 74% after 2000 cycles at 1C.
