Is the cathode material of BYD blade battery lithium iron phosphate or lithium ternary?

I'm sure you've all heard of BYD's recent boom, especially its "blade battery", but do you know the difference between blade batteries and other lithium batteries? In fact, blade battery belongs to lithium iron phosphate battery, lithium iron phosphate is the cathode material used in lithium batteries. Using iron as the raw material of rechargeable batteries has low cost, no heavy metals and little environmental pollution. p-o bonds in lithium iron phosphate crystals are solid bonds and do not leak when stored at zero operating voltage. Safety factors such as high temperature or overcharge time, fast charge, high discharge rated power, no memory, high cycle life, low ultra-low temperature characteristics, low vibration density, low energy, product yield and consistency are also questioned. The full name of ternary lithium battery is ternary material battery. Generally, it refers to the use of Ni-Co-Li-MnO2 (li(nicomn)O2, ncm) or Ni-Co-Al-Al (nca) ternary battery cathode material. Nickel salt, cobalt salt and manganese salt were used as proportion regulator of three different components. So-called ternary batteries include many different types of rechargeable batteries. From the different appearance, can be divided into soft pack battery, cylindrical rechargeable battery and square shell rechargeable battery. Its nominal power is higher than energy, high working voltage service platform, high vibration density, high mileage, large power, high reliability at high temperature, but has excellent ultra-low temperature characteristics, high engineering cost.

From the above mentioned three yuan and the advantages and disadvantages of lithium battery and lithium iron phosphate power can highlight the advantage of lithium ion battery phosphate is safe and stable, long life cycle system, the disadvantage is that the temperature differential characteristics, energy is relatively low, and lithium ion battery that can be used to ensure efficient energy relative density, but poor high temperature characteristics, safety and reliability than lithium ion battery is a bit poor phosphate. With the rise of the new energy vehicle industry, the application of rechargeable batteries is more and more common. Lithium-ion batteries in cars are no stranger. Even apart from pure electric vehicle configuration, it is the best example in other areas, such as mobile phones. Everything has good and bad, in a good application level, to fully grasp. The advantage of lithium-ion batteries is that they have no memory and operate at a wide temperature range. The reliability of the shell focus is maintained even if it runs for a long time. Lithium-ion batteries are divided into lithium-ion batteries and lithium-ion rechargeable batteries.

The lithium-ion batteries are more flexible than traditional rechargeable batteries, making them suitable for quick charging. Can store more than 80% of the battery in a short time, locking polarity is strong. It has high power and longer battery life without harming chemicals. The drawbacks of ternary lithium-ion batteries, most of which currently operate in liquid or colloidal systems, are obvious. The shape of a ternary lithium-ion battery looks like this. The liquid or gel in the rechargeable battery doesn't condense, but it slows down because of the colder temperatures in the north in winter. The adverse effect is that the operation system of the rechargeable battery will be reduced, resulting in low charge, low power and even stop running. Rechargeable batteries are actually called very lithium iron phosphate rechargeable batteries. It is often called a rechargeable battery because of its arrangement like a blade inserted into the battery pack. Compared with ternary lithium-ion battery, tip rechargeable battery has stronger cold resistance, and its lithium ion core thermal discharge area is larger, matching high specific energy. The relative density of blade is not higher than that of ternary lithium battery, but the safety factor is higher than that of ternary lithium battery. Compared with the instability of ternary lithium battery, cutter rechargeable battery has richer safety performance and longer service life.
