9LiFePO 4 •Li 3 V 2 (PO 4 ) 3 /C is synthesized via a carbon thermal reaction using petroleum coke as both reduction agent and carbon source. The as-prepared material is not a simple mixture of LiFePO 4 (LFP) and Li 3 V 2 (PO 4 ) 3 (LVP), but a composite possessing two phases: one is V-doped LFP and
