摘要：
Lithiated spinel manganese dioxide LiMn2O4 Was directly synthesized via solid state reaction of metal lithium with electrolytic manganese oxide (EMD) to avoid the influence of irrelevant elements in the synthesis process. X-ray diffraction diagram indicates that this material exists in the phase of pure spinel crystal. The electrochemical properties of directly synthesized LiMn2O4 were examined by measuring its voltammetry, charge-discharge performance and AC impedance in 1 M LiPF6, 1:1 ethylene carbonate (EC)/dimethyl carbonate (DMC) solution. The results showed that this material represents good properties for intercalation reaction of lithium ions. (C) 2002 Elsevier Science B.V. All rights reserved.
