What is a ternary lithium battery and how long is the life of a ternary lithium battery?

As the society promotes energy conservation and environmental protection, more and more environmentally-friendly products are being used in shopping malls. In the battery industry, ternary lithium batteries quickly occupied the market by virtue of many advantages, and gradually replaced traditional lead-acid batteries. For traditional batteries, the ternary lithium battery has the advantages of long life, energy saving, environmental protection, pollution-free, low maintenance cost, complete charge and discharge without memory effect, and light weight. These advantages have undoubtedly expanded the influence of lithium batteries in the market. It is always said that the ternary lithium battery has a long life, so how long is it in the end? 1. What is a ternary lithium battery? A ternary lithium battery refers to a lithium secondary battery that uses three transition metal oxides of nickel, cobalt and manganese as the positive electrode material. It fully integrates the outstanding cycling function of lithium cobalt oxide, the high specific capacity of lithium nickel oxide, the high safety and low cost of lithium manganate, and other characteristics. It uses molecular level mixing, doping, coating and surface finishing methods to synthesize nickel. Cobalt and manganese and other multi-element synergistic composite lithium intercalation oxides. It is a lithium-ion rechargeable battery that is now widely researched and applied. 2. How long can a ternary lithium battery last? The so-called lithium battery life refers to that the capacity of the battery decays to 70% of the nominal capacity (the battery capacity at room temperature 25°C, standard atmospheric pressure, and discharge at 0.2C) after a period of time, and the life can be considered to stop. The industry generally calculates the cycle life based on the number of cycles of full charge and overflow of lithium batteries. (The specific reason for failure is usually internal crystallization) The theoretical life of a ternary lithium battery is about 800 cycles, which is classified as medium among commercial rechargeable lithium batteries. Lithium iron phosphate is about 2,000 cycles, while lithium titanate is said to be able to reach 10,000 cycles. However, after the batteries are assembled into a battery pack, due to consistency problems, the main voltage and internal resistance cannot be completely the same, and the cycle life is about 400 times. The manufacturer recommends that the SOC application window is 10%~90%. Deep charging and discharging is not recommended, otherwise it will cause irreversible damage to the positive and negative structure of the battery. If it is calculated by shallow charge and shallow discharge, the cycle life will be at least 1000 times. In addition, if lithium batteries are frequently discharged under high-rate and high-temperature environments, the battery life will be drastically reduced to 200 times. Because the discharge rate exceeds its own rate for a long time, the high temperature involved in the faster discharge reaction is still the first hazard factor of battery life, and it is also relatively dangerous. In addition, the number of life cycles of a lithium battery is also related to the quality of the battery. Better materials and processes will still produce lithium batteries with a longer service life. 1. Theoretically, the number of cycles of ternary data is about 800-1200. . 2. The theoretical cycle number of lithium iron phosphate battery is about 2500-3500 times. Shenzhen Electronics Co., Ltd. long-term manufactures battery packs, ternary lithium batteries, lithium iron phosphate batteries, lithium iron manganate batteries, lithium ion batteries and so on. The product has a wide range of applications and high quality. Electronics is a well-known manufacturer of customized battery power supply that ranks among the top in China. Ternary lithium battery function: relatively balanced data in terms of capacity and safety. The cycle function is better than normal lithium cobalt oxide. In the early stage, due to technical reasons, its nominal voltage is only 3.5-3.6V, which is limited in the scope of application. Now, with the continuous improvement of the formula and the perfect structure, the nominal voltage of the battery has reached 3.7V, and the capacity has reached or exceeded the level of lithium cobalt oxide batteries. 1. The voltage specification is high, and the discharge can reach 3.6 or 3.7 volts. 2. High energy density 3.
