Phase‐Transition Engineering Enables Low‐Strain Cathodes for 192 Wh kg − 1 Sodium‐Ion Batteries

Shufen Ye, Yilin Zhang, Junjie Ding, Guihong Mao et autres

ABSTRACT Phase transitions in sodium layered transition metal (TM) oxides often induce microstrain and TM ion migration, leading to structural degradation and poor cycling stability. However, a rational design approach for optimizing phase transitions is still lacking. Here we introduce phase transition …
