Losses occur because the charging voltage is always higher than the rated voltage to activate the chemical reaction within the battery. Energy Efficiency. While the coulombic efficiency of lithium-ion is normally better than 99 percent, the energy efficiency of the same battery has a lower number and relates to the charge and discharge C-rate
In practical terms, battery efficiency is the percentage of energy recovered from the battery after a full charge-discharge cycle. Thus, you can compute it by dividing the energy output by the energy input and multiplying your answer by 100. The discharge current and voltage combine to provide the energy output; that is their product.
For example, if a lithium-ion battery has an energy efficiency of 96 % it can provide 960 watt-hours of electricity for every kilowatt-hour of electricity absorbed. This is also referred to as round-trip efficiency. Whether a BESS achieves its optimum efficiency depends, among others, on the Battery Management System (BMS).

The ability of a battery to hold and release electrical energy with the least amount of loss is known as its efficiency. It is expressed as a percentage, representing the ratio of energy output to input during the battery charging and discharging processes.
Early LIBs exhibited around two-fold energy density (200 WhL −1) compared to other contemporary energy storage systems such as Nickel-Cadmium (Ni Cd) and Nickel-Metal Hydride (Ni-MH) batteries .
Due to the presence of irreversible side reactions in the battery, the CE is always less than 100%. Generally, modern lithium-ion batteries have a CE of at least 99.99% if more than 90% capacity retention is desired after 1000 cycles . However, the coulombic efficiency of a battery cannot be equated with its energy efficiency.
