Enhanced electrochemical performance of surface modified LiCoO2 for all-solid-state lithium batteries
Source abstract
Abstract
Abstract Li 2 CO 3 -coated LiCoO 2 powders are prepared from a lithium hydroxide solution via low-temperature heat treatment and the effects on the electrochemical performance of all-solid-state lithium ion batteries (ASS-LIBs) using Li 2 S-P 2 S 5 glass-ceramic solid electrolytes are investigated. A combination of X-ray diffraction, Fourier transform infrared spectroscopy, and thermogravimetric analyses reveals that the Li 2 CO 3 particles on the surface of LiCoO 2 particles are formed without significant change in LiCoO 2 structure. While the Li 2 CO 3 is regarded as an impurity phase in lithium battery systems using liquid electrolytes due to its detrimental effects on electrochemical performance, we show that optimal amounts of Li 2 CO 3 coating effectively suppress interfacial side reactions without a significant decrease in interfacial kinetics for all-solid-state lithium battery systems using sulfide solid electrolytes.
