Surface modification of LiCoO2 with nano Li2SO4 for all-solid-state lithium ion batteries using Li2S-P2S5 glass-ceramics

Lithium-ion secondary batteries have been generally used as promising power sources for hybrid electric vehicles due to their high energy density. Conventional liquid organic electrolytes have a number of inherent limitations and drawbacks. Solvent of electrolytes has safety problems for batteries in large scale devices due to its flammability.
