Formation of Mn-Cr mixed oxide nanosheets with enhanced lithium storage properties.

Novel carbon-free MnO/MnCrO hybrid nanosheets are synthesized through thermal decomposition of the facilely co-precipitated Mn-Cr binary hydroxide and a carbonate hybrid precursor. As an anode for lithium-ion batteries, the MnO/MnCrO electrode delivers a wonderful electrochemical performance, , an enhanced stability of 913 mA h g at a current density of 1 A g after 300 cycles, and an excellent rate performance. The excellent electrochemical performance of the MnO/MnCrO electrode can be ascribed to the interconnected nanosheets and porous structure, as well as the possible synergistic effects between Mn and Cr mixed oxides.
