What is the Common Type of Power Lithium-ion Batteries?
2022-03-10
Generally speaking, the most talked about power lithium-ion batteries include: lithium iron phosphate batteries, lithium manganate ion batteries, lithium cobalt-ion batteries and ternary lithium-ion batteries (ternary nickel cobalt manganese). So what are the advantages and disadvantages of these batteries?
1. lithium iron phosphate
Advantages: long service life, charge and discharge multiplier, safety, high-temperature, non-polluting elements, low generation cost.
Disadvantages: low energy density, low bulk density.
2. ternary lithium
Advantages: high energy density, high bulk density.
Disadvantages: low safety, low high-temperature resistance, low service life, small high-power discharge, elemental toxicity (ternary lithium-ion batteries in high-power charge and discharge after the temperature will rise rapidly, after the high temperature will release oxygen, very easy to burn).
3. Lithium manganate
Advantages: high bulk density, low production cost.
Disadvantages: low temperature resistance, lithium manganate in a long time after the application, the temperature will rise rapidly, will shrink the service life of the battery.
4. Lithium cobaltate
Generally used in 3C products, its safety is very poor, not suitable as a power lithium-ion battery.
In fact, what we want is a large energy density, bulk density, good safety, high temperature and low temperature resistance, long service life, non-toxic and harmless, high-power charge and discharge, low cost and other advantages of all-in-one lithium battery. But today there is no such battery, so it is necessary to choose between the advantages and disadvantages of different types of batteries. In addition, different electric vehicles have different demand points for batteries, so a long-term judgment of electric vehicles is needed to help everyone choose the right choice of battery route.
