Graphite@MoO3 composite as anode material for lithium ion battery in propylene carbonate-based electrolyte

Graphite@MoO3 composite was prepared by coating MoO3 on graphite in order to improve the performance of graphite as an anode for lithium ion battery in propylene carbonate (PC)-based electrolyte. The coated MoO3 layer acts as a protective layer which separates graphite from PC-based electrolyte solution. Cyclic voltammograms and discharge-charge measurement suggest that the cointercalation of PC is suppressed and lithium ions can reversibly intercalate into and deintercalate from the graphite@MoO3 composite.
