Magnesium/chloride co-doping of lithium vanadium phosphate cathodes for enhanced stable lifetime in lithium-ion batteries

Combining XRD with ³¹ P NMR, it is demonstrated that the Mg and Cl atoms of the new Mg and Cl co-doped Li ₃ V ₂ (PO ₄ ) ₃ /C material occupy V and O sites in its structure, respectively.
