Figure 5. Initial discharge profile of Li₃V₂(PO₄)₃/C cathode obtained by pyro synthesis within the cycling potential range of (a) 3 – 4.3 and (b) 3 – 4.8 V with corresponding cyclabilities and Coulombic efficiencies in the insets.

The differential capacity (dQ/dV) plots for the half-cells tested under (c) 3–4.3 V and (d) 3–4.8 V conditions.
