In terms of shape, they can be divided into soft batteries, cylindrical batteries and square hard-shell batteries. Its rated voltage can reach 3.6-3.8V, with relatively high energy density, high voltage platform, high tap density, long cruise range, large output power, poor high temperature stability, but excellent low temperature performance and relatively high cost.
What is a ternary lithium battery? The full name of a ternary lithium battery is "ternary material battery", which generally refers to the use of lithium nickel cobalt manganate (Li(NiCoMn)O2, NCM) or lithium nickel cobalt aluminate ( NCA) Lithium batteries with ternary cathode materials use nickel salt, cobalt salt and manganese salt as three different component ratios and adjust them differently, so they are calledThese are “ternary” and include many types of batteries with different ratios. . Distinguished by their shape, they can be divided into soft batteries, cylindrical batteries and square hard-shell batteries. Its rated voltage can reach 3.6-3.8V, with relatively high energy density, high voltage platform, high tap density, long cruise range, large output power, poor high temperature stability, but excellent low temperature performance and relatively high cost.
Battery industry experts believe that blade batteries have five major advantages
1. According to the raw material standard system, the conceptual energy density can reach 350 watt hours per kilogram, so the development potential is enormous compared to lithium iron phosphate which is important.
2. Volumetric energy densityhas been considerably improved. With the patented “blade battery” technology, the volumetric energy density of the PACK exceeds 330 watts per hour/L, which can be improved by 30% or more compared to the inherent battery system.
3. The cost is significantly reduced by 30% or more. By reasonably saving raw materials, labor costs, etc., the cost of batteries is expected to be significantly reduced by 30%.
4. Good heat dissipation performance. Since the "blade battery" is thinner than the traditional prismatic battery, the heat dissipation effect is stronger.
5. It has a unique high security battery combination, very safe and reliable. The difference between blade batteries and ternary lithium batteries is very obvious. The biggest advantage of lithium iron phosphate is safety, stability and cycle. The disadvantages of a long lifespan are mpoor low temperature performance and relatively low energy density. Ternary lithium batteries can achieve relatively high energy density, but have poor high temperature performance and slightly lower safety and stability than lithium iron phosphate. If the "blade battery" launched by BYD can really effectively solve the problem of energy density and its price is very competitive, it will still have great market potential.

Lithium-ion battery and ternary battery What are the differences between lithium batteries
Ternary lithium batteries are a type of lithium battery, except that the positive electrode of this battery is a ternary material. Ternary materials refer to nickel, cobalt, and manganese, respectively. The anodes of certainTernary lithium batteries will be made of nickel, cobalt and aluminum.
Ternary lithium battery is a battery with better performance, and most pure electric vehicles use this type of battery.
Ternary lithium batteries are lightweight and have high energy density. This battery is awesome.
Some pure electric vehicles use lithium iron phosphate batteries. Their energy density is not as high as that of ternary lithium batteries, but their safety performance is better than that of ternary lithium batteries.
Ternary lithium batteries will burn at 200 degrees Celsius, while lithium iron phosphate batteries will start burning at 800 degrees Celsius.
Most automakers have done a lot of work to improve the safety of ternary lithium batteries.
Most vehiclesFully electric cars have a huge battery, usually attached to the vehicle's chassis.
The battery box of pure electric vehicles can protect the battery, and pure electric vehicles also have very intelligent battery management modules.
If used normally, the safety of pure electric vehicles is very good.
Purely electric vehicles constitute the development trend for automobiles of the future. Encouraged by national policies, many consumers have purchased purely electric vehicles.
Pacific Automotive Network 1. The main materials are different: Lithium battery materials mainly include lithium cobalt acid, lithium iron phosphate, etc. ; The materials of ternary lithium batteries are based on nickel salt, cobalt salt, and manganese salt as raw materials. 2. Different appsations: lithium batteries are used in large electric vehicles: buses, electric cars, etc. ; Ternary lithium batteries are used in mobile and wireless electronic equipment, power tools and other fields.
Ternary polymer lithium battery refers to a lithium battery with ternary cathode material using lithium-nickel-cobalt-manganese oxide or lithium-nickel-cobalt aluminate as cathode material. Batteries with ternary material as cathode are better than cobalt-acid batteries. Lithium batteries are very safe, but the voltage is too low when used on mobile phones, there will be an obvious feeling of insufficient capacity. Lithium-ion batteries are chemical batteries that use lithium as a negative active material. Lithium has the most negative standard electrode potentialtif, the lightest density among metals and the highest reactivity. Therefore, the electromotive force and specific energy of lithium batteries are very high and are an important high-energy battery.
SANYO, PANASONIC, SONY, LG and SAMSUNG, the world's five largest battery cell brands, have launched ternary material batteries. A considerable number of laptop battery lines have replaced the previous ones with ternary material batteries. Cobalt oxide batteries, SANYO and SAMSUNG column batteries have completely stopped the production of lithium cobalt oxide batteries and switched to the manufacturing of ternary batteries. Most high-rate small batteries at home and abroad use ternary cathode materials.
