Article Synopsis
  • To address the growing energy needs, researchers are exploring potassium-ion batteries (KIBs) as a viable alternative to the widely used lithium-ion batteries (LIBs) due to KIBs' abundance and comparable energy densities.
  • A key focus in enhancing KIB performance involves developing efficient electrode materials, with particular attention on layered metal oxides for KIB cathodes, which are noted for their high capacity and stability.
  • The review discusses the advancement of these layered metal-oxide cathodes, examining their design, preparation methods, and performance challenges, while also highlighting future opportunities for practical KIB applications.

NaCrO with high rate-capability is an attractive cathode material for sodium-ion batteries (NIBs). However, the amount of reversibly extractable Na ions is restricted by half, which results in relatively low energy density for practical NIB cathodes. Herein, we describe aliovalent-doped O3-Na[CrSn]O (NCSnO) and O3-Na[CrSb]O (NCSbO), both of which show high-voltage characteristics that translate to an increase in energy density.
