AI Customer ServiceThe equilibrium voltage is OCV. The OCVs after different discharge rates are totally different and increases with the increase of discharge rate. The OCV drift caused by thermodynamics can be neglected during the initial few cycles, because there is no apparent active lithium ion loss at this stage.
Two important parameters in battery ICs are overvoltage threshold and undervoltage threshold. These numbers are the voltage levels at their limit; the IC will cut the cell out of circuit if the cell is being overcharged or over-discharged. These values are typically designed into battery protection ICs.
Lithium batteries have the advantage of high energy density. However, they require careful handling.
