The carbon-coated Li9V3(P2O7)3(PO4)2 (LVPP/C) composite is prepared via carbon thermal reduction.
The Li-storage properties of LVPP/C are investigated, both as cathode and anode for Li-ion batteries.
An intercalation reaction mechanism for LVPP/C anode is firstly confirmed by in-situ XRD.
The LVPP(cathode)//LVPP(anode) symmetric batteries is designed and investigated.
