What are the classifications of ternary material lithium batteries

Ternary lithium batteries have excellent electrochemical characteristics such as high energy density, good safety and stability, support high-rate discharge, and the cost advantages of moderate prices. They are used in the field of small and medium-sized lithium batteries such as consumer digital electronic products, industrial equipment, and medical instruments. Has been widely used. ①Ternary polymer lithium battery A ternary polymer lithium battery refers to a lithium battery that uses nickel cobalt manganese lithium ternary cathode material as the anode material and uses a gel polymer electrolyte. As the transmission medium of ion movement, electrolyte is generally composed of solvent and lithium salt. The electrolyte of lithium secondary battery mainly includes liquid electrolyte, ionic liquid electrolyte, solid polymer electrolyte and gel polymer electrolyte. Its biggest advantage is the high mechanical strength of the diaphragm, and the membrane provides a large surface area. The thinner the film, the higher the energy density, because more active materials can be embedded in the battery. ②Ternary power lithium battery The so-called power ternary lithium battery means that the battery supports high-rate and high-current discharge, has high power density, and releases a lot of energy per unit time. The rate-discharge capability refers to the ability to maintain the battery capacity when the charge-discharge rate is increased. The rate of charge and discharge is represented by xC. 1C means that the nominal capacity of the battery can be used up in 1h, while the rate of discharge at 2C can be used for 30min. For the ternary power lithium battery, the most researched and most mature technology is undoubtedly the Japanese company Panasonic. The 30C discharge has been achieved in the test stage, and the power type 18650 ternary lithium battery has been successfully processed on a commercial scale. The discharge rate Up to 12C, the capacity is as high as 3300mAh. ③The low-temperature characteristics of the ternary low-temperature lithium battery The low-temperature characteristics of the lithium battery are important to be investigated from the low-temperature discharge characteristics and cycle life. The most important thing for the low-temperature battery is to maintain the fluidity of the material under low-temperature conditions, so that lithium ions can freely shuttle between the positive and negative electrodes. Realize battery charging and discharging. At present, domestic and foreign ternary lithium battery manufacturers can basically achieve a discharge temperature of -20 degrees, and the discharge capacity is greater than 50%, and the cycle life is about 400 times, which can fully meet the general electrical appliances and electrical scenarios.
