14650

History #

The 14650 battery is a lithium-ion cell that was first introduced in the early 2000s. It is a relatively new type of battery, but has quickly become a popular choice for many applications. The 14650 battery is a cylindrical cell that measures 14mm in diameter and 65mm in length. It is also known as an 18650 cell due to its similar size and shape.

Typical Chemistry #

The 14650 battery typically contains a positive electrode made of lithium cobalt oxide (LiCoO2) and a negative electrode made of graphite. The electrolyte is typically a liquid solution of lithium salt in an organic solvent. The cells are usually sealed with a metal casing to prevent leakage.

Typical Use #

The 14650 battery is commonly used in a variety of applications, including portable electronics, medical devices, and automotive applications. It is a popular choice for portable electronics due to its relatively high energy density and long life. The 14650 battery is also used in medical devices such as pacemakers and insulin pumps, as well as in automotive applications such as electric vehicles and hybrid vehicles.

Design #

The 14650 battery is a cylindrical cell that measures 14mm in diameter and 65mm in length. It has a nominal voltage of 3.6V and a capacity of up to 2500mAh. The cells are usually sealed with a metal casing to prevent leakage. The cells are typically equipped with a protection circuit to prevent overcharging and overdischarging. The cells are also equipped with safety vents to release pressure in the event of an overcharge or overdischarge. The cells are usually designed with a positive terminal on one end and a negative terminal on the other.
