It is common belief that conventional layered oxide battery cathode materials operate on a cationic redox mechanism, and that oxygen oxidation triggered by charge compensation results in oxygen loss and limited practical capacity. In this work, thin

The sodium (Na) anode suffers severe interfacial resistance and dendrite issues in a classic NASICON-type Na3Zr2Si2PO12 (NZSP) electrolyte, resulting in poor electrochemical performance for solid-state Na metal batteries. There has been little succes

All-solid-state sodium batteries are attractive due to the abundance of sodium and advantageous for safe battery operation by avoiding flammable organics and liquids and suppressed dendrite formation. Currently, the lack of a chemically stable sodium

A common way to improve the electrochemical performance of the NaxCoO2 thin-film cathodes is to increase their crystallinity. Here we present our study of the electrochemical performance of all-solid-state sodium ion batteries with NaxCoO2 thin-film

On the way to sodium-based all-solid-state batteries, interface analysis is a key issue. In this work, the interface between two typical solid sodium-ion conductors (Na-β″-Al2O3 and NASICON) and the layered oxide material NaCoO2 is investigated. T
