· JVASP-144790· Na2Ni3O7

Na2Ni3O7 is a mixed-metal oxide ceramic compound containing sodium, nickel, and oxygen, belonging to the family of transition-metal oxides with potential electrochemical and thermal applications. This material is primarily investigated in research contexts for energy storage systems (particularly as a cathode material in sodium-ion batteries) and catalytic applications, where its layered structure and mixed-valence nickel states offer advantages over single-metal oxides. Engineers considering this compound should note it remains largely experimental; adoption would depend on cost-effectiveness compared to established lithium-ion alternatives and the maturing sodium-ion battery market.
