What are the classification and application scope of ternary lithium batteries?

Ternary lithium battery is a kind of lithium battery. It refers to the lithium battery whose cathode material is lithium nickel cobalt manganate or lithium nickel cobalt aluminate. Ternary materials refer to nickel, cobalt and manganese respectively. The anode of some ternary lithium batteries will be made of nickel, cobalt and aluminum. So, what are the classifications and application ranges of ternary lithium batteries?

 Ⅰ.Classification of ternary lithium batteries

 1.Ternary polymer lithium battery

Ternary polymer lithium battery refers to the lithium battery whose cathode material is lithium nickel cobalt manganate (Li (NiCoMn) O2) ternary cathode material and uses 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.

 2.Ternary power lithium battery

The ternary power lithium battery refers to the battery that supports high rate and high current discharge, high power density and more energy released per unit time. The rate discharge capability refers to the ability to maintain the battery capacity when the charge discharge rate increases. The rate of charge and discharge is expressed in 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.

 3.Ternary low temperature lithium batteryThe temperature characteristic of the battery is an indicator of battery reliability, and the performance of the battery can also be evaluated by changing the ambient temperature. The low temperature characteristics of lithium battery are mainly investigated from the low temperature discharge characteristics and cycle life. The most important thing of the low temperature battery is to maintain the fluidity of materials under low temperature conditions, so that lithium ions can freely shuttle between the positive and negative electrodes to achieve battery charging and discharging.

 Ⅱ.Application scope of ternary lithium battery

The ternary lithium battery has excellent electrochemical characteristics such as high energy density, good safety and stability, high rate discharge support, and moderate cost advantages. It has been widely used in consumer digital electronic products, industrial equipment, medical instruments and other small and medium-sized lithium battery fields, and has shown strong development potential in intelligent robots, AGV logistics vehicles, unmanned aerial vehicles, new energy vehicles and other power lithium battery fields.

The ternary lithium battery has stable output voltage, high output voltage, stable performance, large capacity, long service life, wide operating temperature range, good safety and environmental protection and pollution-free, so it has great room for improvement in the future development of lithium battery.
