Life of ternary polymer lithium battery

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 ρu003d. Lithium is chemically active and easily loses electrons and is 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 indicates that the energy density of ternary lithium-ion batteries is higher than power under the same volume and net weight. It is worth mentioning that lithium-ion batteries have great advantages in terms of charging and cold resistance. Lithium-ion battery as a lithium-ion battery charger has 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 kind of lithium-ion battery rechargeable lithium-ion battery, which is currently widely researched and applied. For ternary lithium-ion batteries, the number of biological scientific researches is the largest, and the most complete technology is Panasonic Corporation of Japan. The experimental link has been able to charge and discharge 30c. Among them, the successful commercial mass production of 18650 lithium-ion batteries has a charge-discharge rate of 12c, and the volume It can also reach 3300mah. There are also many ternary polymer lithium ion manufacturers in China, which have been relatively successful. The life of a ternary polymer lithium battery; the life of a lithium battery generally refers to the application of a rechargeable battery for a period of time, and the volume attenuation coefficient is 70% of the tolerable volume (room temperature 25℃, standard atmospheric pressure and charge and discharge battery capacity), which can be considered Is termination. In the manufacturing industry, the life of the circulatory system is estimated by the frequency of the circulatory system full of lithium. During the entire application process, lithium-ion batteries will undergo irreversible electrochemical corrosion, such as the dissolution of lithium battery electrolyte, the dissolution of specific raw materials, and the breakdown of positive and negative structures will lead to a reduction in the number of lithium-ion batteries. Experiments have shown that the charging and discharging of polymers will cause a rapid decay coefficient of the volume. If the charging and discharging current is low, the battery voltage will be close to the equilibrium working voltage, which can release a lot of kinetic energy. In theory, the life of a ternary lithium-ion battery is 2000 battery charging cycle system. We calculate that it can last for more than five years if it is charged once a day. It is strongly recommended that the soc application dialog box is 10% 90%. In many aspects, it is not recommended to charge the battery, otherwise it will cause irreversible harm to the positive and negative structure of the battery. In addition, if lithium is often charged and discharged under the natural environment and high temperature of the polymer, the number of battery cycles will be greatly reduced to less than 200 times.
