Introduce the application fields of cylindrical lithium-ion batteries

Classification of cylindrical lithium-ion batteries Cylindrical lithium-ion batteries are divided into three materials: lithium cobalt oxide and lithium manganate. There are three materials for the system battery, which have their own advantages. They are widely used in: notebook computers, digital cameras, lighting, toy products, power tools, portable energy and other fields. There are many types of cylindrical lithium-ion batteries, such as 14650, 17490, 18650, 21700, 26650, etc. Cylindrical lithium-ion batteries are very popular among lithium-ion battery companies in Japan and South Korea. Cylindrical lithium-ion batteries, the important models are 18650, 16650, 14500. 18650 means 18 mm in diameter and 65 mm in length. The No. 5 battery is 14500, with a diameter of 14mm and a length of 50mm. Generally speaking, 18650 batteries are mostly used in industry and less in civilian use. Ordinary batteries are mostly used for laptop batteries and high-end flashlights. Cylindrical lithium-ion battery. JPG14500 battery 14500 battery diameter 14mm, 50mm high lithium-ion battery, we are called battery 5 size, the battery is 3.7V and 3.2V, the rated capacity is very small, slightly larger than the 10440 battery, generally 1600mah, superior discharge performance, Important consumer electronic products in the application field, such as wireless audio, electric toys, digital cameras, etc. 16340 Battery The 16340 battery is a lithium-ion battery with a diameter of 16mm and a height of 34mm. This kind of battery is low in height and small in capacity, so it often appears in strong light flashlights, LED flashlights, headlights, lasers and lighting devices. 18650 battery The 18650 battery is a lithium-ion battery with a diameter of 18 mm and a height of 65 mm. Its biggest feature is a very high energy density, almost reaching 170 watts/kg, so the battery is very cost-effective. We often see The most is the battery, because it is a relatively mature lithium-ion battery, with good quality in all aspects of system stability, and is widely used in the case of about 10KWH battery capacity, for example, in mobile phones, notebook computers and other small appliances. 21700 battery 21700 battery is a lithium-ion battery with a diameter of 21 mm and a height of 70 mm. Because of its size, space utilization, energy density, battery cells and systems can be improved, its volumetric energy density is much higher than that of the 18650 battery. Used in digital, electric cars, balance cars, solar street lights, LED lights, lithium-ion batteries, power tools, etc. How to charge the cylindrical lithium-ion battery? If the cylindrical lithium-ion battery is used in a working environment above 35C, the battery power will continue to drop, which means that the battery life will not be as long as usual. If you have to charge the device at this temperature, the damage to the battery will be even greater. Prevent charging at too low temperature. If you use a lithium-ion battery in a low temperature environment, that is, below 4°C, you will also find that the battery life is reduced. Do not use special methods to activate the lithium-ion battery. The lithium-ion battery will be naturally activated when the machine is in normal use. Shallow charging is more beneficial to lithium-ion batteries. Only when the product's power module is calibrated to a lithium-ion battery, deep charging is required. Therefore, the use of lithium battery products does not need to be constrained by the process, all for convenience, charging at any time, do not have to worry about the impact on life. Application areas 1. Energy storage is mainly used in base station power supplies, clean energy, grid energy storage, and home optical storage systems. 2. The power category mainly refers to electric vehicles, electric bicycles, new energy vehicles, etc. 3. Digital mobile phones, tablet computers, notebook computers, electric toys, MP3/MP4, earphones, charging bags, model airplanes, mobile power supplies, etc. Lithium-ion batteries have a wide range of applications. Cylindrical lithium-ion batteries have high energy density and high average output voltage. Moreover, its self-discharge is small. You should understand that a good battery is very durable, because the cylindrical lithium-ion battery has no memory effect, so it is very durable and has a long life.
