摘要:
A sodium-ion battery includes a cathode comprising sodium; and an anode composition comprising a material having the formula: AaBbCcDdO, where A is an alkali metal, alkaline earth metal, or a combination thereof, where B is titanium, C is vanadium, D is one or more transition metal element other than titanium or vanadium, a+b+c+d≦1, a≧0, b+c>0, b≧0, c≧0, d>0, and where the material comprises a ilmenite structure, triclinic VFeO4 structure, cubic Ca5Co4(VO4)6 structure, dichromate structure, orthorhombic ∀-CoV3O8 structure, brannerite structure, thortveitite structure, orthorhombic ∃-CrPO4 structure, or the pseudo rutile structure.
