Ag-deposited mesocarbon microbeads as an anode in a lithium ion battery with propylene carbonate electrolyte

Nano-silver particles were deposited on graphitized mesocarbon microbeads (MCMB) with a low coverage by a wet chemical method. It was found that the existence of nano-Ag boosted the formation of a stable solid electrolyte interface (SEI) film on the surface of MCMB in propylene carbonate (PC)-based electrolyte. Consequently, a reversible lithium intercalation/deintercalation process was observed. It is shown from the preliminary result that the deposition of nano-silver particles on MCMB has improved the cycling performance of MCMB/Li cell in PC-based electrolyte.
