What is the classification and application range of ternary lithium battery?
Ternary lithium battery is a kind of lithium battery, which refers to the cathode material using ternary positive material of lithium nickel-cobalt-manganate or lithium nickel-cobalt-aluminate. The ternary material refers to nickel, cobalt and manganese respectively. The anode of some ternary lithium battery will be made of nickel, cobalt and aluminum. So, what are the categories and applications of ternary lithium batteries?
I.Classification of ternary lithium batteries
1. Ternary polymer lithium battery
Ternary polymer lithium battery refers to the lithium battery which uses the cathode material of lithium nickel cobalt manganate (Li (NiCoMn) O2) ternary cathode material and uses the gel polymer electrolyte. Electrolyte, as the transmission medium of ion movement, 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. Three-way power lithium battery
Ternary power lithium battery refers to the battery supports high rate and large current discharge, high power density, and releases more energy per unit time. Rate discharge capacity refers to the ability of the battery to maintain capacity when the rate of charge and discharge increases. The rate of charge and discharge is expressed as xC, 1C means that the nominal capacity of the battery can be used up in 1 hour, while the rate of discharge at 2C can be used up for 30 minutes.
3. Three-way low-temperature lithium battery
The temperature characteristic of a battery is an indicator of its reliability, and its performance 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 of low-temperature batteries is to maintain the liquidity of substances under low temperature conditions, so that lithium ions can freely shuttle between the positive and negative electrodes, and realize the battery charging and discharging.
Two, three lithium battery application range
Ternary lithium battery with high energy density, good safety and stability, support high rate discharge and other excellent electrochemical characteristics, as well as moderate cost advantage, in consumer digital electronic products, industrial equipment, medical instruments and other small and medium-sized lithium battery fields have been widely used, and in intelligent robots, AGV logistics vehicles, The power lithium battery sector, such as drones and new energy vehicles, shows strong development potential.
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 no pollution, so there is a lot of room for improvement in the future development of lithium battery.
