History #

The 16650 battery is a lithium-ion rechargeable battery, first seen in the early 2000s. It was developed as an alternative to the 18650 battery, which was the standard for laptop batteries at the time. The 18650 battery had some limitations, such as its size and capacity, which the 16650 battery was designed to address.

The 16650 battery is a cylindrical battery, measuring 16mm in diameter and 65mm in length. It has a nominal voltage of 3.7V and a capacity of 2000mAh. It has a higher capacity than the 18650 battery, but a slightly lower voltage.

Typical Chemistry #

The 16650 battery is typically made with a lithium-ion chemistry. This type of chemistry is very popular in rechargeable batteries due to its high energy density and long life.

The 16650 battery is made up of three main components: the anode, the cathode, and the electrolyte. The anode is usually made of graphite, while the cathode is typically made of lithium cobalt oxide or lithium manganese oxide. The electrolyte is usually a combination of lithium salts and organic solvents.

Typical Use #

The 16650 battery is most commonly used in laptop batteries, flashlights, and other portable electronics. It is also used in some electric vehicles, such as electric bicycles and electric scooters.

The 16650 battery is popular because of its high capacity and low weight. It is also relatively inexpensive, making it an attractive option for many consumers.

Design #

The 16650 battery is designed to be as small and lightweight as possible, while still providing a high capacity and long life. To achieve this, the battery is made with a cylindrical shape and a high-capacity lithium-ion chemistry.

The 16650 battery is designed to be rechargeable, and can be recharged hundreds of times before it needs to be replaced. It is also designed to be safe, with built-in safety features such as over-charge protection and short-circuit protection.

The 16650 battery is designed to be used in a wide range of applications, from laptop batteries to electric vehicles. It is also designed to be reliable and long-lasting, with a lifespan of up to five years.
