Graphite@MoO 3 composite was prepared by coating MoO 3 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 MoO 3 layer acts as a protective layer which separates graphite from PC-based electrolyte solution.
The calculated results indicate that PC is initially oxidized on the cathode to a radical cation intermediate, PC(*+), and then decomposes through three pathways, generating carbon dioxide CO(2) and radical cations. The detailed oxidative decomposition mechanism of propylene carbonate (PC) in the lithium ion battery is investigated using …
