What are the advantages and disadvantages of ternary lithium-ion batteries?
The advantages of three-way lithium-ion battery are smaller volume, higher capacity density, low temperature resistance and better cycle performance, which is the mainstream of new energy passenger vehicles.
The disadvantage of ternary lithium ion battery is: poor thermal stability, decomposition will occur at 250-300℃ high temperature, and the chemical reaction of ternary lithium material is especially strong, once the release of oxygen molecules, under high temperature use of electrolyte combustion rapidly, then deflation phenomenon.
How long is the life of a ternary lithium battery?
The theoretical life of ternary lithium battery is 1200 times of full charge and discharge, that is, full cycle life. According to the use frequency, charge and discharge once every three days, 120 times a year, the service life of the three-way lithium battery reaches about 10 years. The service life of the battery is affected by a variety of factors, such as the driver's habit and normal maintenance. The actual use of the battery shall prevail.
Three cathode material of lithium ion battery, lithium ion battery cathode material has many kinds, important lithium cobalt acid, lithium manganese acid, lithium nickel acid, ternary material, lithium iron phosphate and so on. The three-component material integrates the advantages of lithium cobalt, lithium nickelate and lithium manganate, and has excellent characteristics such as high capacity, low cost and good safety. It gradually occupies a certain market share in small lithium electricity, and has a good development prospect in the field of power lithium electricity.
