Abstract
The Li0.44Mn1-yTiyO2 of y=0 and 0.22 with a same tunnel-typed structure, which were prepared from the corresponding Na compounds via Li/Na-ion exchange, were immersed in the organic solvents of n-hexane containing n-butyl-lithium. Several samples of Li0.44+xMn1-yTiyO2 (x=0 to 1) were obtained via the chemical insertion controlling x by the concentration of n-butyl-lithium. The SEM observation, ICP analysis, powder X-ray diffraction measurement, and charge-discharge test were carried out on them. In their X-ray diffraction patterns, as x increased, the peaks shifted toward low angle, and then, the intensities decreased and the pattern became broad.
