Lithium-ion batteries, as an important energy storage device, are widely used in electric vehicles, drones, energy storage systems, and other fields. They come in various power specifications to meet the needs of different devices. The following are commonly used power specifications of lithium-ion batteries and their application areas:
18650 battery
The 18650 battery is a common lithium-ion battery type, named for its 18mm diameter and 65mm length. These batteries typically feature high energy density and cycle life, and are widely used in portable electronic devices, laptops, power tools, and other applications. Due to their moderate size, 18650 batteries are also widely used in electric vehicles and energy storage systems.
21700 battery
The 21700 battery is a new type of lithium-ion battery that has emerged in recent years. It has a diameter of 21mm and a length of about 70mm. Compared with the 18650 battery, the 21700 battery has a higher energy density and greater discharge power, and therefore has been widely used in electric vehicles, power tools, and high-capacity energy storage systems.
26650 battery
The 26650 battery is a large lithium-ion battery with a diameter of approximately 26mm and a length of approximately 65mm, featuring high energy density and discharge power. Due to its large size, the 26650 battery is typically used in applications requiring high capacity and high power output, such as large power tools, energy storage systems, and special vehicles.
pouch battery
A pouch battery is a lithium-ion battery without a fixed outer casing. Its outer packaging is made of soft-pack material, allowing for flexible design as needed. Pouch batteries typically have a lighter weight and higher energy density, making them widely used in portable electronic devices, electric bicycles, and balance scooters.
Custom-specification batteries
In addition to the common specifications mentioned above, power lithium batteries also come in many customized specifications to meet the needs of specific devices. These customized batteries are typically designed to meet specific requirements for power, energy density, size, and safety, and are widely used in high-end fields such as special vehicles, aerospace, and medical equipment.
Power lithium batteries come in a variety of commonly used power specifications, each optimized for different application areas and needs. With continuous technological advancements, it is believed that even more new lithium battery specifications will emerge in the future, providing more choices and possibilities for the development of various power devices.
