A green and low-cost strategy was employed to manufacture kg-level monoclinic Li3V2(PO4)(3) (LVP) and spinel LiCrTiO4 (LCTO) electrode materials with excellent Li-ion storage capability. The manufactured LVP parallel to LCTO Li-ion full cells showed a capacity of 646.5 mA h and an impressive cycling capability of 800 cycles with only 0.36 parts per thousand capacity loss per cycle at 500 mA. This higher Li-ion storage capacity was attributed to the excellent electrochemical reversibility of Li3V2(PO4)(3) cathode and LiCrTiO4 anode.
Active electrode materials are given main responsibility for the electrochemical performance of Li-ion full cells. Hence, it is essential to pursue cost-effective manufacturing techniques for electrode materials. In this study, a green and low-cost strategy is employed to manufacture kg-level monoclinic Li3V2(PO4)(3) (LVP) and spinel LiCrTiO4 (LCTO) electrode materials, both of which display excellent Li-ion storage capability with high reversible capacities and a long lifespan. The manufactured LVP parallel to LCTO Li-ion full cells have demonstrated a capacity of 646.5 mA h and an impressive cycling capability of 800 cycles with only 0.36 parts per thousand capacity loss per cycle at 500 mA. The higher Li-ion storage capacity of full LIBs is explained by the excellent electrochemical reversibility of Li3V2(PO4)(3) cathode and LiCrTiO4 anode.
