Charge efficiency can be improved by increasing the ion concentration equilibrium during the charging process, which affects the degree of ion diffusion in a lithium-ion battery. Consequently, the battery life can be increased and charge time optimized with this strategy; so it is widely used in advanced battery-charge systems [ 51, 52, 74 ].

Understanding Lithium-ion

Figure 1: Ion flow in lithium-ion battery When the cell charges and discharges, ions shuttle between cathode (positive electrode) and anode (negative electrode). On discharge, the anode undergoes oxidation, or loss of electrons, and the cathode sees a reduction, or a gain of electrons. Charge reverses the movement.
