Superior rate capability is a game-changer for an electrode material, enabling the use of thick electrodes and hence compensating the moderate specific capacity at the full-cell level by reduced dead weight/volume (e.g., the mass/volume of the active material which does not participate in the electrochemical response) .A nice example is LIB technology based on

During the long period of charge and discharge, a large number of Li vacancy defects are generated, which not only oxidize Fe 2+ to Fe 3+, but also induce the migration of partial Fe 2+ to the Li site, forming the so-called "anti-site" defects, which has a negative effect on Li + diffusion, accompanied by the failure of the cathode of the LFP battery.
