Lithium-ion battery technology is viable due to its high energy density and cyclic abilities. Different electrolytes are used in lithium-ion batteries for enhancing their efficiency. These electrolytes have been divided into liquid, solid, and polymer electrolytes and explained on the basis of different solvent-electrolytes.
Li-ion batteries consist of an anode and a cathode based on various redox chemical couples with an electrolyte and separator in between. The electrolyte conducts ions, not electrons, through the separator and between the anode and cathode (Figure 1). Electrolytes can take various forms, with dissolved salts being the most common form.
Lithium-ion batteries power everything from smart phones and laptops to electric cars and large-scale energy storage facilities. Batteries lose capacity over time even when they are not in use, and older cellphones run out of power more quickly. This common phenomenon, however, is not completely understood.
Increasing the charge cutoff voltage of a lithium battery can greatly increase its energy density. However, as the voltage increases, a series of unfavorable factors emerges in the system, causing the rapid failure of lithium batteries.
