文摘
- •
Deliquescent-LiVO3 was used as an electrolyte binder for LiCoO2 based cathode.
- •
LiVO3 and LiCoO2 composite electrode was easily prepared by coating the mixed slurry of LiCoO2 powder and LiVO3 aqueous solution on an Al foil and drying it at 150 °C.
- •
LiVO3–LiCoO2 composite electrode showed the discharge capacity of 79% for the theoretical capacity.
- •
The LiVO3 in the composite electrode operated as Li ion conductive paths in the range between 3.0 and 4.25 V.
- •
Recovery of discharge capacity was found by dissolving the LiVO3 in the composite electrode after cycle test.
