Pioneering work of the lithium battery began in 1912 under G.N. Lewis, but it was not until the early 1970s that the first non-rechargeable lithium batteries became commercially available. Attempts to develop rechargeable lithium batteries followed in the 1980s but failed because of instabilities in the metallic lithium used as anode material ...
In a good lithium-ion battery, the difference in electron electrochemical potential between the electrodes is mostly due to the electric potential difference Δ ϕ resulting from (chemically insignificant amounts of) excess charge on the electrodes that are maintained by the chemical reaction.
In the following, we show first that the chemical potential of lithium atoms in the cathode is equal to the difference in the molar Gibbs free energies, or chemical potentials, of FePO 4 and LiFePO 4, which are the cohesive free energies used in our analysis above. Then we express the cell voltage in terms of a difference of chemical potentials.
The voltage is generated by the charging and discharging process of the Li-ions from the anode and cathode. Reactions shown also apply to solid-state batteries, although the choice of material is atypical here, Own illustration. During discharge, the Li-ions migrate from the anode to the cathode. LCO is a cathode with a layered structure.
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).
In the following sections, we will review computational approaches to key properties of lithium-ion batteries, namely the calculation of equilibrium voltages and voltage profiles, ionic mobilities and thermal as well as electrochemical stability.
