What are the classifications of ternary lithium batteries?

Classification of ternary lithium battery ⒈Ternary polymer lithium battery A ternary polymer lithium battery refers to the use of lithium nickel cobalt manganate (Li (NiCoMn) O2) ternary positive electrode material and the use of gel polymer electrolyte lithium Battery. 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. ⒉Ternary power lithium battery The so-called power lithium ion 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 capacity 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 experimental stage has been able to achieve 30C discharge, of which the power type 18650 ternary lithium battery has been successfully commercialized and large-scale processed. Up to 12C, the capacity is as high as 3300mAh. There are also domestic manufacturers that achieve a higher discharge rate, but the stability of the battery needs to be improved, especially after a period of use, its cycle life and rate discharge capacity will be greatly reduced. ⒊The temperature characteristic of the ternary low-temperature lithium battery is an indicator of the reliability of the battery, and the performance of the battery can also be evaluated by changing the ambient temperature. The low-temperature characteristics of lithium batteries are mainly investigated from the low-temperature discharge characteristics and cycle life. The most important thing for low-temperature batteries 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 to realize the charge and discharge of the battery. At present, ternary lithium battery manufacturers at home and abroad 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 ordinary electrical appliances and electrical scenarios. However, in special products such as aerospace and military equipment, or in severe cold environments such as northern and high mountains, lithium batteries must be able to reach a lower discharge working temperature to meet harsh operating conditions.
