If these electrodes come in direct contact, due to a short circuit the battery will drain out completely. As its name specifies, a separator keeps the anode and cathode apart. SeparatorĪ separator is an important part of a battery since it saves the battery from an internal short circuit. KOH is a good conductor and is thus a perfect choice as an electrolyte. It is due to this compound that alkaline batteries got their name. Alkaline batteries use l iquid Potassium hydroxide (KOH) as the electrolyte. The electrolyte is the medium to transfer electrons between anode and cathode. Manganese oxide is mixed with graphite to increase its conductivity. Manganese dioxide is used in alkaline batteries as its cathode. The cathode accepts the electrons released by the anode. The zinc is mixed with potassium hydroxide solution to form a paste. Alkaline batteries use zinc as the anode. The anode has the capacity to release electrons. In an alkaline battery, the negative terminal is the base cap at the other end of the battery. The negative terminal connects the anode to the circuit. Similar to the cathode, the anode also lies inside the battery, while the negative terminal lies outside. In an alkaline battery, the positive terminal is a s mall projection at one end of the battery. The positive terminal connects the cathode to the circuit. But generally, both these terms are used interchangeably while discussing battery terminals.Īctually, the cathode is present inside the battery, while the positive terminal of the battery lies outside and is visible to us. Note: The positive terminal does not mean the cathode. A plastic wrapper is placed over this case which shows us the specifications and the terminals of the battery. It acts as a holder and keeps the battery components and insulation away from the ambient. The case is the outermost covering of the battery. Must read: Important Battery Terms & Characteristics Explained (with Examples) The case Let us see the components of a commercial alkaline battery in detail. The inner layers of an alkaline battery are shown in the figure above. This happens only when the battery is connected to the circuit. The chemical composition of the battery is designed in such a way that the electron from one electrode flows through the electrolyte to the other electrode. Electricity is basically the flow of electrons. In simple words, the battery produces electricity when the two electrodes immersed in the electrolyte react together. ![]() But the commercial batteries consist of a few more components that make them reliable and easy to use. ![]()
