Novel MnO/carbon composite anode material with multi-modal pore structure for high performance lithium-ion batteries

Abstract

A new type of MnO/carbon composite particle with multi-modal pore structure was designed and prepared as anode materials of lithium-ion batteries through a promoted template method. The porous MnO/carbon composite anode materials exhibited the superior electrochemical performance, including excellent stability under different current density, high reversible capacity (as high as 1210.9 mA h gāˆ’1 after 700 cycles at 1.0 A gāˆ’1), good rate capability and high initial coulomb efficiency of over 80%, which had benefited from the reasonable material composition, special multi-modal pore structure, desirable micro-morphology and good structural integrity. The complex multiphase structure consisting of MnO crystal grains, abundant nanopores and uniform carbon layers can effectively improve cyclic stability and rate capability of the anode materials, and thus will have an important application value in high-performance energy supply devices.
