An active cathode material containing particles with a core containing a lithium transition metal oxide, each core at least partially encapsulated by a layer including the lithium transition metal oxide and dopant cation; and an outer layer containing metal oxide; wherein the dopant cation is selected from the group consisting of Al, Ti, Sn, Mg, Zr, Cu, Fe, Ca, W, Ga, Sc, Y, La, Hf, V, In, Nb, Ta, and any combination of two or more thereof; and the dopant cation is present in an amount of 10 wt. % or less of the particle.

Cathode materials for secondary batteries

An electrochemical device includes an air cathode comprising a SEI (solid electrolyte interphase) layer on a carbon support.

Cathode for alkaline earth air batteries

A metal-air battery includes an anode; a low-dimensional catalyst cathode; and an electrolyte; wherein: the low-dimensional catalyst cathode comprises a functional metal layer on a carbon support overcoated with a catalyst layer; the electrolyte comprises an aprotic solvent that is an ether-based solvent, a fluorinated ether-based solvent, an oligo (ethylene oxide) solvent, or a mixture of any two or more thereof; and the electrolyte is free of carbonate solvents.
