18650 battery
An 18650 battery or 1865 cell is a cylindrical battery size (often lithium-ion battery or sodium ion battery) common in electronic devices. The batteries measure 18 mm (0.71 in) in diameter by 65.0 mm (2.56 in) in length, giving them the name 18650. The battery comes in many nominal voltages depending on the specific chemistry used.
Sony developed the 18650 in 1991, though Panasonic claims to have done so in 1994. They are commonly used in power tools, electric bicycles, laptops, and electric vehicles.
18650 batteries are most commonly lithium-based.
NMC811 can be doped with ZrO2 to produce a cathode for these batteries.
By 2023, some sodium-ion variants were available in the 18 mm × 65 mm cylindrical cell form factor as well.[better source needed]
In 2024, a potassium-ion variant was unveiled in the 18650 format that utilizes a proprietary 4 V Potassium Prussian White cathode and a commercially available graphite anode.
18650 batteries are commonly used in packs, where a battery management system (BMS) is required, especially once cells age and perform differently. BMS boards balance the voltage of cells in series and protect against over- and under-discharge.
18650 battery cells are used in a wide variety of products from the 1990s through the 2020s, and are widely regarded as the most produced lithium-ion cell size. 18650 cells are used in many laptop computer batteries, cordless power tools, many electric cars, electric scooters, most e-bikes, older portable powerbanks, electronic cigarettes, portable fans, and LED flashlights. Nominal voltage is 3.6–3.7 V.
