Therefore, lithium batteries should be disposed of with care. Moreover, an important difference between alkaline and lithium batteries is that the lithium batteries are toxic, and alkaline batteries are not so. (Lithium battery gives a brighter light beam when used in a torch). Thus, the power is higher in the lithium battery. Thus, this makes lithium batteries ideal for portable devices.Īs another difference between alkaline and lithium batteries, usually, lithium batteries give 1.75 V or more whereas alkaline batteries give 1.5V. Moreover, Lithium batteries are lighter in weight than alkaline batteries. The key difference between alkaline and lithium batteries is that the lifetime of lithium batteries is much higher than the alkaline batteries. What is the Difference Between Alkaline and Lithium Batteries?Īlkaline battery is an electrochemical cell with an anode and a cathode that produces electricity through a chemical reaction while a Lithium battery is a type of battery that uses lithium or lithium compounds as the anode. For instance, AA battery produces 700 mA current. There are different sizes of the battery (AA-, AA, AAA, etc.), and the current produced by the battery depends on the size. The usual voltage for an alkaline battery is 1.5 V, and we can increase the voltage by having a series of batteries. Following are the two half-reactions taking place in the electrodes. The electrolyte in the battery is potassium hydroxide. And the positive terminal or the cathode is made of manganese dioxide. The anode or the negative electrode of the alkaline battery is made of zinc powder. Side by Side Comparison – Alkaline vs Lithium Batteries in Tabular FormĪlkaline battery is an electrochemical cell with an anode and a cathode that produces electricity through a chemical reaction. Except for the brand names, we can divide these batteries into two types according to the chemistry of generating electricity. There are lots of batteries under various brand names in the market today. Using batteries are safer than using the main electricity directly. For example, alarm clocks, remote controllers, toys, torches, digital cameras, radios are working with the current supplied by a battery. Although most of the equipment is now directly working with electricity, a lot of other small or portable devices need batteries.

We need batteries every day in our household necessities. The key difference between alkaline and lithium batteries is that the lifetime of lithium batteries is much higher than that of the alkaline batteries.
