Alkaline Batteries

Alkaline batteries were first introduced in 1959 by Lewis Urry, a Canadian engineer working for the Union Carbide Corporation.

Alkaline batteries marked a significant improvement over the existing carbon-zinc batteries, offering longer life and better performance.

An alkaline battery consists of several cells, each containing a cathode (positive electrode) made of manganese dioxide (MnO2) and an anode (negative electrode) made of zinc. These electrodes are separated by an alkaline electrolyte, typically potassium hydroxide (KOH). The electrodes and electrolyte are contained within a metal or plastic housing.

Alkaline batteries are primarily designed for single-use, meaning they are not intended to be recharged. They are typically known for their relatively high energy density, longer shelf life, and better performance in high-drain devices compared to carbon-zinc batteries. They are one of the most widely used types of batteries in various applications, including portable electronics, toys, flashlights, remote controls, portable gaming devices, portable fans, radios, wall clocks and many other consumer devices.

The come in a variety of shapes, such as AA, AAA, D, C and 9V
