What are the benefits of ternary lithium batteries?

Experts believe that compared with other cathode materials, ternary materials have the advantages of better product consistency, good cycle performance, higher energy density, and high cost performance. The future market for batteries must be ternary materials. In fact, ternary materials have been favored by more and more manufacturers in recent years. From 2007 to 2011, the output of ternary materials has maintained a rapid increase for 5 years. Last year, the total output of the country reached 8,500 tons. At present, Chery Automobile has begun to study the use of ternary materials to process automotive batteries. In addition, dozens of battery manufacturers have expressed plans to increase the use of ternary materials. It is reported that among a variety of battery cathode materials, currently only ternary materials can achieve the energy density of 180wh/kg. Moreover, some manufacturers use a ceramic coating on the PE film to improve the heat resistance of the diaphragm and also enhance the safety of the nickel, cobalt, manganese and lithium ternary materials. At present, an important factor hindering the wide application of ternary materials is high cost. It is reported that the current first-line brand of lithium iron phosphate material is 130,000/ton, while the ternary material is 150,000. However, the price of ternary materials has been falling year by year in recent years. In addition, if it is processed on a larger scale, the cost will also be reduced more drastically. Ternary polymer lithium battery refers to a lithium battery that uses lithium nickel cobalt manganate (Li (NiCoMn) O2) as the cathode material. The precursor product of the ternary composite cathode material is nickel salt, cobalt salt, and manganese salt. As raw materials, the ratio of nickel, cobalt and manganese can be adjusted according to actual conditions. The battery with ternary material as the positive electrode is relatively safe for lithium cobalt oxide batteries, but the voltage is too low for use in mobile phones (the cut-off voltage of mobile phones is generally around 3.4V ) There will be an obvious feeling of insufficient capacity. Ternary lithium battery performance: a relatively balanced material in terms of capacity and safety. The cycle performance 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 use. At present, 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.
