Baterai Alkaline: Sumber Listrik yang Andal dan Tahan Lama

An alkaline battery is a type of battery that uses a chemical reaction between a metal anode and a metal cathode to generate electricity. These batteries are known for their reliable performance, long shelf life, and wide range of applications.

How Alkaline Batteries Work

Alkaline batteries work on the principle of electrochemical reactions between the anode and cathode. When an alkaline battery is connected to a circuit, the anode (usually zinc) reacts with the cathode (usually manganese dioxide) to produce electricity. The reaction is as follows:

Zn (zinc) + 2MnO2 (manganese dioxide) + 2H2O (water) → Zn(OH)2 (zinc hydroxide) + 2Mn(OH)2 (manganese hydroxide) + electricity

Advantages of Alkaline Batteries

Alkaline batteries have several advantages that make them a popular choice for many applications:

Reliable performance: Alkaline batteries are known for their reliable performance, which makes them a popular choice for applications where reliability is critical.
Long shelf life: Alkaline batteries have a long shelf life, which means they can be stored for extended periods without losing their performance.
Wide range of applications: Alkaline batteries are used in a wide range of applications, including flashlights, radios, and toys.
Low self-discharge: Alkaline batteries have a low self-discharge rate, which means they can be stored for extended periods without losing their charge.

Applications of Alkaline Batteries

Alkaline batteries are used in a wide range of applications, including:

Flashlights: Alkaline batteries are commonly used in flashlights due to their reliable performance and long shelf life.
Radios: Alkaline batteries are used in radios due to their reliable performance and low self-discharge rate.
