TL;DR: A comprehensive review on the latest advances and progresses in the exploration of layered oxides for SIBs is presented, and a detailed and deep understanding of the relationship of phase transition, air stability, and electrochemical performance in layered oxide cathodes is provided in terms of refining the structure-function-property relationship to design improved battery materials as mentioned in this paper.

TL;DR: This study describes a thin asymmetrical design of solid electrolyte to address the contradictory requirements from Li-metal and cathode, which need high modulus to block Li-dendrite penetration and flexibility to enable low interface resistance, respectively.

TL;DR: It is demonstrated that Na+/vacancy disordering of P2-type layered cathodes ensures both fast Na mobility and a low Na diffusion barrier in P1-type compounds, opening up a new route to precisely design high-rate cathode materials for rechargeable NIBs.

TL;DR: It is disclosed that NVPF-NTP presents the best power performance among the state-of-the-art cathode materials for SIBs, and when coupled with an Sb-based anode, the fabricated sodium-ion full-cells also exhibit excellent rate and cycling performances, thus providing a preview of their practical application.

TL;DR: A series of sodium-sufficient O3-type NaNi0.5-x Ti x O2 cathodes for SIBs is reported and the mechanisms behind their excellent electrochemical performance are studied in comparison to those of their respective end-members.
