Abstract
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 Li 3 V 2 (PO 4 ) 3 (LVP) and spinel LiCrTiO 4 (LCTO) electrode materials, both of which display excellent Li-ion storage capability with high reversible capacities and a long lifespan. The manufactured LVP || 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‰ capacity loss per cycle at 500 mA. The higher Li-ion storage capacity of full LIBs is explained by the excellent electrochemical reversibility of Li 3 V 2 (PO 4 ) 3 cathode and LiCrTiO 4 anode. ● A green and low-cost strategy is employed to prepare Li 3 V 2 (PO 4 ) 3 /C (LVP/C). ● LiCrTiO 4 (LCTO) microspheres are constructed with the spray-drying route. ● LVP/C and LCTO both exhibit excellent Li-ion storage capability. ● High-performance energy storage device of LVP//LCTO full LIBs are achieved.
