A battery is a device that converts energy into electricity by storing electrical energy through chemical reactions. There are three main components in a battery [4]. The first component of a battery is a terminal called an anode which is an electrode through which electric current flows [2]. The second component of a battery is a terminal called a cathode which is an electrode through which electric current flows [2]. These two terminals are found at each end of a battery. The third component of a battery is called electrolyte and is one or more ionic compounds used to separate these two terminals, send electrons and used to neutralize the charges that accumulate in chemical reaction processes [2]. In the process To produce electricity, the anode of a battery produces electrons through an oxidation reaction while the cathode accepts these electrons creating a flow of electrons [4]. Electrons are transported and transferred by electrolytes, which act as a piece of metal between the anode and cathode [4]. In the case of primary batteries, the chemical reactions are irreversible, meaning that the products produced in the chemical reactions to produce electricity cannot return to their reactant (original) state [4]. Therefore, this type of battery depletes its energy production over time [4]. On the other hand, the chemical reactions in a rechargeable battery are reversible, which means that the products produced in the chemical reactions to produce electricity can return to their original state by using an external electrical power source [4]. Below are the two types of battery with certain specific batteries:I. Primary Batteries - These batteries are sometimes called single-use or "disposable" batteries... middle of paper......chemical reactions involving variables of the following chemicals: Oxidation (anode): C+x〖 Li〗 ^+ (aq)xe^-→CLix [8]Reduction (cathode):LiCoO_2→〖Li〗_(1-x) CoO_2+〖xLi〗^++xe^- [8]• Lead-acidThis battery is the most popular among rechargeable batteries [1]. This battery offers advantages like lithium ion battery being economical and reliable [1]. However, due to its weight, the lead acid battery is not as portable as other batteries. Furthermore, this battery contains lead, a toxic and carcinogenic compound, which is its main chemical component [1]. The chemicals involved in this battery are porous lead as anode, lead(IV) oxide as cathode and sulfuric acid as electrolyte. Oxidation (anode):Pb(s)+〖HSO_4〗^- (aq)→〖PbSO〗_4 (s)+H^+ (aq)+2e^- [2].Reduction (cathode):PbO_2 (s )+〖〖HSO〗_4〗^- (aq)+3H^+ (aq)+2e^- →Pb〖SO〗_4 (s)+2H_2 O(l) [2].
