| 제목 | Highly ordered mesoporous Ni-Mn composite oxide with stabilized nanostructure for high electrochemical properties in lithium ion batteries |
| 초록 | In lithium-ion battery, transition metal oxides exhibit high capacities. However, these materials have several general 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, meso nickel manganese oxides(NMO) were prepared by the nanocasting method using manganese nitrate and nickel nitrate precursor. N2 isotherms show that mesoporous NMO has a specific BET surface area of 140m2/g and a pore diameter of 3nm and 10nm. 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. |
