Although this expression is well known, it only valid to determine the activity properly by electrochemical techniques in rechargeable lithium batteries by Coulometric titration or by derivation from Gibbs free energy of formation of the relevant compound for the condition at equilibrium.
Li-ion batteries typically use ether (a class of organic compounds) as an electrolyte. Lithium ions are stored within graphite anodes through a mechanism known as intercalation, in which the ions are physically inserted between the 2D layers of graphene that make up bulk graphite.
Not only are lithium-ion batteries widely used for consumer electronics and electric vehicles, but they also account for over 80% of the more than 190 gigawatt-hours (GWh) of battery energy storage deployed globally through 2023.
Simply storing lithium-ion batteries in the charged state also reduces their capacity (the amount of cyclable Li+) and increases the cell resistance (primarily due to the continuous growth of the solid electrolyte interface on the anode).
A Li-ion battery consists of a intercalated lithium compound cathode (typically lithium cobalt oxide, LiCoO 2) and a carbon-based anode (typically graphite), as seen in Figure 2A. Usually the active electrode materials are coated on one side of a current collecting foil.
In part because of lithium’s small atomic weight and radius (third only to hydrogen and helium), Li-ion batteries are capable of having a very high voltage and charge storage per unit mass and unit volume. Li-ion batteries can use a number of different materials as electrodes.
