Lithium iron ii phosphate

LFP has two shortcomings: low conductivity (high overpotential) and low lithium diffusion constant, both of which limit the charge/discharge rate. Adding conducting particles to delithiated FePO 4 increases its . 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 to 95% of the theoretical values..
