battery 18650

　　What is a ternary polymer battery 18650?

　　In nature, lithium is a light metal material with the lowest atomic mass, and its relative atomic mass is the smallest. Its atomic weight is, ρ=. Lithium has active chemical properties and can easily lose electrons and be oxidized to Li+. Lithium is a raw material with high energy density. Generally refers to lithium ions using lithium nickel cobalt manganate as the battery cathode material and high-purity graphite as the battery cathode material. Different from lithium phosphate batteries, ternary lithium-ion batteries have a higher operating voltage service platform, which shows that the energy density of ternary lithium-ion batteries is higher than the power under the same volume and weight. It is worth mentioning that lithium-ion batteries have great advantages in terms of charging and cold resistance.

　　As a lithium-ion battery charger, lithium-ion batteries have the advantages of stable output voltage, high output voltage, stable characteristics, large capacity, long use time, wide operating temperature range, good safety factor, and no pollution. It is a lithium-ion rechargeable lithium-ion battery that is currently widely researched and applied.

　　For ternary lithium-ion batteries, there are the largest number of biological research studies. The most complete technology is Panasonic Company of Japan. The experimental link has been able to charge and discharge 30c. Among them, the successful commercial mass production of 18650 lithium-ion battery has a charge-discharge rate of 12c and a volume of 12c. It can also reach 3300mah. China is still a manufacturer of ternary polymer lithium-ion batteries, which has been very successful. For example, Shenzhen Volume Ratio High-Tech Co., Ltd. has been established for 19 years and has excellent production technology. The production of ternary polymer lithium-ion batteries has become a batch of Chinese companies. product.

　　The service life of ternary battery 18650

　　In short, battery 18650 life generally refers to the use of rechargeable batteries for a period of time. The volume attenuation coefficient is 70% of the tolerated volume (room temperature 25°C, standard atmospheric pressure and charge and discharge battery capacity), which can be considered to be terminated. In manufacturing, circulatory system life is estimated by the frequency of lithium-filled circulatory systems. During the entire application process, lithium-ion batteries will undergo irreversible electrochemical corrosion. For example, the dissolution of battery 18650 electrolyte, the dissolution of specific raw materials, and the collapse of the positive and negative structures will lead to a reduction in the number of lithium-ion batteries. Experiments show that the charge and discharge of polymers will lead to a rapid attenuation coefficient of volume. If the charge and discharge current is low, the battery voltage will be close to the equilibrium operating voltage and a large amount of kinetic energy can be released.

　　Theoretically, the life of a ternary lithium-ion battery is 2,000 battery charging cycles. We calculate that it can last for more than five years with one charge per day. It is strongly recommended that the SOC application dialog box is 10%90%. In many aspects, battery charging is not recommended, otherwise it will cause irreversible damage to the positive and negative structures of the battery. In addition, if lithium is often charged and discharged in the natural environment and high temperature of the polymer, the number of battery cycles will be greatly reduced to less than 200 times.
