Solid–liquid ratio is an important parameter in plant operation that is directly related to the amount of chemical reagents used and indirectly influences the operating cost. As shown in Fig. 1 (b), high leaching efficiency of lithium ions was maintained with increasing solid–liquid ratio, achieving 99.95 % recovery at conditions of 20–50 g/L.

LFP has two shortcomings: low conductivity (high overpotential) and low lithium diffusion constant, both of which limit the charge/discharge rate. Adding conducting particles in delithiated FePO 4 raises its electron conductivity. For example, adding conducting particles with good diffusion capability like graphite and carbon to LiMPO 4 powders significantly improves conductivity between particles, increases the efficiency of LiMPO 4 and raises its reversible capacity up to 95…
