The basic composition of an energy storage battery includes the following key components:Anode: The negative electrode where oxidation occurs.Cathode: The positive electrode where reduction takes place.Electrolyte: A medium that allows the flow of ions between the anode and cathode.Separator: A barrier that prevents direct contact between the anode and cathode while allowing ionic movement1.Additionally, common materials used in the cathode include lithium cobaltate (LCO), lithium iron phosphate (LFP), and ternary materials like lithium nickel-cobalt manganate (NCM)2.
