Since EVs are estimated to make up 7% of the global transportation market by , the availability of lithium and other rare metals required for manufacturing batteries and the disposal of lithium-ion batteries will become more critical factors in the life cycle analysis of EVs.
Lithium-ion battery technology is implemented for electric vehicles and spacecraft because of its high usable energy, prolonged life cycle, battery safety, and low self-discharge. A lithium battery pack needs an efficient battery management system (BMS) to monitor the individual cell voltage, current, temperature, state of charge, and discharge.
The lithium-ion battery, which is used as a promising component of BESS that are intended to store and release energy, has a high energy density and a long energy cycle life .
Since lithium-ion batteries (LIBs) have long been the primary energy source for electric vehicles (EVs), their intrinsic qualities such as their high energy density, extended cycle life, and low self-discharge rate have made LIBs ubiquitous in the field.
The objectives are as follows: Maximize the energy density of a lithium-ion cell subject to a power requirement. Determine electrode morphological designs at optimal cell designs under various discharge rates. Quantify the relative sensitivity of the design variables on cell performance.
To meet the increased power capacity and voltage requirements for electric vehicle (EV) applications, hundreds of lithium-ion cells are combined in series and parallel to form a battery pack, as individual cell capacity and voltage levels are insufficient to drive the motor load (Feng et al., 2022; Gandoman et al., 2022).
