抄録

LiNiO₂, LiNi_1/2Co_1/2O₂, and LiCoO₂ were prepared and characterized by XRD and FT-IR. XRD data for these three samples indicated that lithium ions were located at octahedral 3 (b) sites and transition metal ions at 3 (a) sites in a cubic close packed oxygen array (space group; R3m). XRD and IR methods to estimate the degree of contamination of rock-salt domain in the solid matrix were described. Electrochemical examinations for the well-characterized samples were also carried out in lithium nonaqueous cells. These three samples exhibited 130-140mAh⋅g^-1 of rechargeable capacity in the working voltage above 3.5V with charge/discharge coulombic efficiency of ca. 97%. The key technology to establish 4-volts secondary nonaqueous lithium cells was briefly described together with a concept on the active material design based on the lithium-transition metal-oxygen ternary phase for a secondary system therefrom.
