Abstract

Abstract : We report on the synthesis and characterization of a novel manganese vanadate, Mn1.5 (H2 O)(NH4 )V4 O12, with rare in situ disorder of Mn(H2 O)2 2+ /2NH4 + . Abstract : We report on the synthesis and characterization of a novel manganese vanadate, Mn1.5 (H2 O)(NH4 )V4 O12, with rare in situ disorder of Mn(H2 O)2 2+ /2NH4 + . We show that vacancies created by ammonium ions and coordinating water molecules within the manganese vanadate crystal structure yield high-charge capacity, favorable rate capability, and long cycle life in Li-ion half-cells.
