Understanding the underlying mechanisms of the charge–discharge behaviour of batteries, especially Li-ion and Na-ion intercalation ones, is obligatory to develop and design energy storage devices. The behaviour of the voltage–capacity/time (V–C/T) diagram is one of the most critical issues which should be understood.
For instance, rechargeable batteries take a long time to self-discharging (weeks or months, e.g., self-discharge in Li-ion battery is < 2–5 % per month), whereas the electrochemical capacitors (ECs), which store energy
An important figure-of-merit for battery energy storage systems (BESSs) is their battery life, which is measured by the state of health (SOH).

Lithium-ion batteries have a high energy density, a long lifespan, and the ability to charge/discharge efficiently. They also have a low self-discharge rate and require little maintenance. Lithium-ion batteries have become the most commonly used type of battery for energy storage systems for several reasons:
Round-trip efficiency is the ratio of energy charged to the battery to the energy discharged from the battery and is measured as a percentage. It can represent the battery system''s total AC-AC or DC-DC efficiency, including losses from self-discharge and other electrical losses. In addition to the above battery characteristics, BESS have other
