1. Introduction. The applications of lithium-ion batteries (LIBs) have been widespread including electric vehicles (EVs) and hybridelectric vehicles (HEVs) because of their lucrative characteristics such as high energy density, long cycle life, environmental friendliness, high power density, low self-discharge, and the absence of memory effect
A battery has normally a high energy density with low power density, while an ultracapacitor has a high power density but a low energy density. Therefore, this paper has been proposed to associate more than one storage technology generating a hybrid energy storage system (HESS), which has battery and ultracapacitor, whose
High power batteries are key in electrically powered transportation, as conventional lithium-ion batteries are incapable of delivering both high energy density and high power required. This is especially true in vertical take off and landing (eVTOL) in electric aircraft, as well as in medium and long-haul trucking when bringing to speed large
Batteries consist of two electrical terminals called the cathode and the anode, separated by a chemical material called an electrolyte. To accept and release energy, a battery is coupled to an external circuit. Electrons move through the circuit, while simultaneously ions (atoms or molecules with an electric charge) move through the electrolyte
Therefore, this paper has been proposed to associate more than one storage technology generating a hybrid energy storage system (HESS), which has battery and ultracapacitor, whose objective is to improve the electric vehicle (EV) driving range.
The same applies to a high current storage into the batteries that generated during the braking of the EV. These fluctuating flows of a high electric current into and from the battery could have a detrimental effect on the electrolytes.

Hybrid vehicles will use the two sources of power automatically and may use both simultaneously. The internal combustion engine and energy recovered from the vehicle braking systems are used to charge the battery. A plug-in hybrid vehicle can have its battery charged directly from the electrical supply network.

The growth in EVs has led to an increase in the growth of discarded batteries, which need to be recycled. The EV batteries are usually discarded after the reduction of 20% of their nominal capacity (Heymans et al., 2014).These discarded EV batteries still have some capacity left, which can be used for alternative applications, for
At least 750,000 registered EVs in the U.S. run on lithium-ion batteries—popular because of their high energy storage but containing a flammable liquid electrolyte component that burns when overheated. While no government agency tracks vehicle fires by type of car, and electric car battery fires appear to be relatively rare,
Similar to acceleration, which discharges the electric energy storage at a high rate, the ability to charge the system at a high rate requires high power handling. Many early and current model all-electric vehicles use only a battery (Berckmans et al., 2017). Starting with this scenario, let us consider a unit that matches E t o t in Eq.

Conversely, Na-ion batteries do not have the same energy density as their Li-ion counterpart (respectively 75 to 160 Wh/kg compared to 120 to 260 Wh/kg). This could make Na-ion relevant for urban vehicles with lower range, or for stationary storage, but could be more challenging to deploy in locations where consumers prioritise maximum range
