I'm sure you've all heard of BYD's recent buzz, 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 a positive electrode material applied in lithium battery. It is cheap to use iron as rechargeable battery raw material, and does not contain heavy metals. p-o bond in lithium iron phosphate crystal is a solid bond, zero operating voltage storage will not leak, high temperature or overcharge time, fast charging, high discharge rating, no memory, high cycle life, low ultra-low temperature characteristics, low vibration density, low energy, product yield and consistency of safety factors are also questioned. The full name of ternary lithium battery is ternary material battery, generally refers to the use of nickel-cobalt lithium manganese dioxide (li (nicomn) O2, ncm) or nickel-cobalt aluminum aluminum (nca) ternary battery cathode material, nickel salt, cobalt salt, manganese salt as the proportion of three different components adjustment, the so-called ternary battery, including many different types of rechargeable batteries. From the appearance of the difference, can be divided into soft packaging battery, cylindrical rechargeable battery and square shell rechargeable battery. Its nominal power is higher than energy, high working voltage service platform, high vibration density, mileage, high power, high temperature reliability, but has excellent ultra-low temperature characteristics, high project cost.

　　Mentioned above ternary lithium battery and lithium iron phosphate power battery and inferiority, can see lithium-ion phosphate battery larger outstanding advantage is the safe and stable, circulatory system life cycle is longer, the disadvantage is that cryogenic properties is poorer, and energy is relatively low, and lithium ion battery that can be used to ensure efficient energy relative density, the characters of high temperature is bad, Compared with lithium ion phosphate battery, the safety and reliability is slightly worse. With the rise of the new energy vehicle industry, the application of rechargeable batteries is becoming more and more common. The use of lithium-ion batteries in cars is not unfamiliar to all, even if in addition to pure electric vehicle configurations, in other areas, such as mobile phones, is the best example. Everything has good and bad. At the level of good application, we should grasp it comprehensively. The beauty of lithium-ion batteries is that they have no memory and operate at a wide range of temperatures. The reliability of shell focus can be maintained even after a long run. Lithium-ion batteries are divided into lithium-ion batteries and lithium-ion rechargeable batteries.

　　The lithium battery is more flexible than traditional rechargeable batteries, suitable for fast charging, can store more than 80 percent of the battery in a short period of time, and has strong locking polarity. It has high power and longer battery life without harming chemicals. The drawbacks of ternary lithium-ion batteries are obvious. Most lithium-ion batteries currently operate in liquid or colloidal systems. Ternary lithium-ion batteries are shaped in such a way that in winter, due to cooler temperatures in the north, the liquid or gel inside the rechargeable battery, while not condensing, will become increasingly slow. The adverse effect is that the operating system for rechargeable batteries will be reduced, leading to power shortages, power shortages and even shutdown. The head rechargeable battery is actually called a very lithium iron phosphate rechargeable battery, it is often called a head rechargeable battery because its arrangement is inserted into the battery pack like a blade. Knife-head rechargeable batteries have better cold resistance than ternary lithium-ion batteries, and their lithium-ion cores have larger total thermal discharge area and higher specific energy to match. The relative density of blade battery is not higher than ternary lithium battery, but the safety factor is higher than ternary lithium battery. Compared with the instability of ternary lithium battery, the knife head rechargeable battery has richer safety performance and longer service life.
