Abstract

Layered Li[Li(1-2x)3]O2 (x=0.35, 0.305 and 0.23) powders with high homogeneity and crystallinity were synthesized using a sol-gel method. The layered structure solid solutions were obtained by Ni substitution for Li and Mn in Li2MnO3. The discharge capacity of the Li[Li(1-2x)3]O2 electrode increased with decrease in Ni concentration.
