History #

The CR2032 battery was first introduced in the early 1990s by the Japanese company, Sanyo. It is a 3-volt lithium coin cell battery, and is one of the most popular sizes of coin cell batteries. It is commonly used in small electronic devices such as watches, calculators, and remote controls.

Typical Chemistry #

The CR2032 battery is a lithium coin cell battery, which means it contains a lithium metal anode and a cathode composed of manganese dioxide. The electrolyte is a non-aqueous solution of lithium salts. This type of battery is known for its high energy density and long shelf life.

Typical Use #

The CR2032 battery is commonly used in small electronic devices such as watches, calculators, and remote controls. It is also used in medical devices, such as glucose meters and hearing aids. It is also used in some toys, such as remote-controlled cars.

Design #

The CR2032 battery is a 3-volt lithium coin cell battery. It has a diameter of 20mm and a thickness of 3.2mm. It has a capacity of approximately 225mAh and a nominal voltage of 3V. The battery is designed with a long shelf life and is known for its high energy density. It is also designed to be lightweight and compact, making it ideal for small electronic devices.

The CR2032 battery has a positive terminal on one side and a negative terminal on the other. The terminals are connected to the cathode and anode, respectively. The battery also has a safety vent to prevent over-pressurization.
