O3/P2 MIXED PHASE SODIUM-CONTAINING DOPED LAYERED OXIDE MATERIALS

摘要

The invention relates to O3/P2 mixed-phase sodium-containing doped layered oxide materials which comprise a mixture of a first phase with an O3-type structure and a second phase with a P2-type structure; wherein the O3:P2 mixed-phase sodium-containing doped layered oxide material has the general formula: Na_aA_bM¹_c M² M³_eM⁴_f M⁵ O_2±δ. The invention also provides a process for making such O3/P2 mixed-phase sodium-containing doped layered oxide materials, and use applications therefor.
