제목 Ordered mesoporous Ni-Mn system with stabilized nanostructure during electrochemical behaviour for lithium ion batteries
초록 In lithium ion batteries, transition metal oxides exhibit high capacities. However, these materials have several disadvantages. Thus, transitional metal oxides are studied for solving the problems by incorporating, with carbon materials and, making binary metal oxide.
Above all, binary metal oxides have been regarded as ideal and potential anode materials, which can improve and offset the electrochemical performance of the single metal oxides, such as reversible capacity, structural stability and electronic conductivity. In this work, mesoporous nickel manganese oxides were prepared by the nanocasting method using manganese nitrate and nickel nitrate precursor.
N2 isotherms show that mesoporous nickel manganese oxide has a specific BET surface area of 140m2/g and a pore diameter of 3nm and 10-20nm. Our as-prepared nickel manganese oxides products were evaluated as the anode material for the LIB. It showed high reversisble capacity with 71% of initial efficiency and good cycle retention during 50cycles.
