Abstract: Substitution of tantalum into the lattice of monoclinic niobium phosphate results in improved reversibility, near 0% irreversible loss, and similar excellent 20 C high rate behavior in large grain material without the formation of electronically conducting nanocomposites. Tantalum substitution into niobium pentaphosphate enables an improved stabilization of the difficult to fabricate monoclinic niobium phosphate phase. Such tantalum-substituted niobium phosphates show excellent potential for use as electrodes in lithium or lithium-ion batteries.
