Batteries are perhaps the most prevalent and oldest forms of energy storage technology in human history. 4 Nonetheless, it was not until 1749 that the term "battery" was coined by Benjamin Franklin to describe several capacitors (known as Leyden jars, after the town in which it was discovered), connected in series. The term "battery" was presumably chosen

Graphite and its derivatives are currently the predominant materials for the anode. The chemical compositions of these batteries rely heavily on key minerals such as lithium, cobalt, manganese, nickel, and aluminium for the positive electrode, and materials like carbon and silicon for the anode (Goldman et al., 2019, Zhang and Azimi, 2022).
While the material used for the container does not impact the properties of the battery, it is composed of easily recyclable and stable compounds. The anode, cathode, separator, and electrolyte are crucial for the cycling process (charging and discharging) of the cell.
Li-ion batteries come in various compositions, with lithium-cobalt oxide (LCO), lithium-manganese oxide (LMO), lithium-iron-phosphate (LFP), lithium-nickel-manganese-cobalt oxide (NMC), and lithium-nickel-cobalt-aluminium oxide (NCA) being among the most common. Graphite and its derivatives are currently the predominant materials for the anode.
This comparison underscores the importance of selecting a battery chemistry based on the specific requirements of the application, balancing performance, cost, and safety considerations. Among the six leading Li-ion battery chemistries, NMC, LFP, and Lithium Manganese Oxide (LMO) are recognized as superior candidates.
The main technologies utilized in rechargeable battery systems include lithium-ion (Li-ion), lead–acid, nickel–metal hydride (NiMH), and nickel–cadmium (Ni–Cd). Rechargeable batteries constitute a substantial portion of the global battery market.
The developed battery concept is based on a composite material and has carbon fiber as both the positive and negative electrodes – where the positive electrode is coated with lithium iron phosphate. When the previous battery concept was presented, the core of the positive electrode was made of aluminum foil.
