The voltage that can be measured on a battery at its poles is the difference of the voltage generated at the respective electrodes: The voltage at the anode and cathode is not a fixed value, but depends on the state of charge of the cell. However, fixed values are often given for the electrodes in the literature (e.g. 3.9 V for LCO, cf. ).
Accurately estimating the state of health (SOH) of lithium-ion batteries in real-world scenarios, especially for electric vehicles (EVs) is challenging due to dynamic operating conditions and limited battery usage data.
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.
