Electrical conductivity of LiClO4 solution in binary solvent of propylene carbonate (PC) and 1,2-dimethoxyethane (DME) coexisting with LiCoO2 powder was measured. Maximum value of conductivity in LiClO4/PC-DME solution observed at ca. 1:1 of volume fraction shifted toward lower content of DME. In higher LiClO4 concentration reached to 3 mol L−1, the conductivity of LiClO4-PC1−xDMEx increased with DME content even if LiCoO2 was added. The results of FT-IR measurement support the results of conductivity measurement for PC solvation of the slurry sample of LiCoO2/LiClO4/PC-DME system.
