17650

History #

The 17650 battery is a type of lithium-ion battery, which has been in use since the early 2000s. It was developed by Sony as a replacement for the 18650 battery, which had been in use since the 1990s. The 17650 battery was designed to be smaller and lighter than the 18650, while still providing the same amount of power.

The 17650 battery was first used in laptop computers and other consumer electronics, but it quickly became popular in electric vehicles and other high-power applications. It is now one of the most popular battery sizes for electric vehicles, and it is also used in a wide range of consumer electronics.

Typical Chemistry #

The 17650 battery typically uses a lithium-ion chemistry. This chemistry is popular because it is lightweight, has a high energy density, and is relatively safe to use. It also has a high voltage, which is ideal for powering electric vehicles.

The typical chemistry for a 17650 battery is a cobalt-oxide cathode and a graphite anode. This combination of materials provides a high energy density and a long lifespan. The battery can be safely charged and discharged hundreds of times without significant degradation.

Typical Use #

The 17650 battery is most commonly used in electric vehicles. It is popular because it is lightweight, has a high energy density, and is relatively safe to use. The battery is typically used in electric cars, electric bicycles, and other electric vehicles. It is also used in consumer electronics such as laptops, tablets, and smartphones.

The 17650 battery is also used in solar energy storage systems. Solar energy storage systems use the battery to store excess energy generated by solar panels during the day, so that it can be used at night. The battery is also used in some medical devices, such as pacemakers and hearing aids.

Design #

The 17650 battery is typically cylindrical in shape, and it is usually about 65 mm in length and 17 mm in diameter. The battery is made up of several layers of cells, which are stacked together to form a single battery. Each cell contains a cathode, an anode, and a separator.

The cathode and anode are typically made from a combination of cobalt-oxide and graphite. The separator is usually made from a polyolefin polymer, which helps to keep the cathode and anode from coming into contact with each other. The cells are then sealed in a metal casing, which helps to protect the battery from damage.

The 17650 battery typically has a capacity of about 2.2Ah, which means that it can store about 2.2 Ampere-hours of energy. The battery can be charged and discharged hundreds of times without significant degradation, and it typically has a lifespan of several years.
