What is 18650 lithium battery

18650 lithium battery is a type of cylindrical lithium battery with a diameter of 18mm and a height of 65.0mm, and a rated voltage of 3.7V. In order to meet the needs of more devices, 18650 lithium battery packs have emerged. They are assembled in series and parallel based on 18650 battery cells to achieve higher voltage and longer discharge time., The safety factor of 18650 lithium battery ternary material as a positive rechargeable battery is higher than that of lithium cobalt oxide battery, but the working voltage is too low. When used on mobile phones (the cut-off voltage on mobile phones is generally above and below), there will be a significant feeling of insufficient capacity. At present, the first type is more commonly used in the sales market.

What is the main purpose of 18650 batteries?
18650 lithium batteries are more stable and robust in the international market, and their market share is also a technological leader in other lithium-ion battery products. It has been widely used in the large, medium, and small lithium battery industries such as consumer digital technology electronic devices, mechanical equipment, and medical machinery. It has also been widely applied in the power lithium battery industry such as service robots, AGV trucks, unmanned aerial vehicles, and new energy vehicles. It has shown strong development prospects in intelligent machines, tablets, laptops, electric toy cars, MP3/MP4, mobile phone headphones, mobile chargers, model airplanes, mobile phones, and other fields.

The advantages of 18650 lithium batteries
The balance of volume and safety factor has stronger cycling characteristics compared to general lithium cobalt oxide raw materials. Due to technical reasons, its early nominal voltage was relatively limited and its application fields were also limited. With the gradual improvement of the secret formula and the refinement of the structure, the nominal voltage of rechargeable batteries has already reached, and the capacity has already reached or exceeded the level of lithium cobalt oxide batteries. So now most people prefer to use 18650 lithium battery packs.
