Analysis of the advantages and disadvantages of blade batteries

The blade battery was redesigned with the shape of the lithium iron phosphate battery and reduced volume. Still belong to lithium iron phosphate batteries. The ternary lithium battery has a high voltage and high energy density, so the power battery pack made of ternary lithium is small. High power storage is high, but the disadvantage is that the ternary lithium battery is not resistant to high temperature, and it is unstable when charging and driving.

But at the same time, it also has all advantages and disadvantages of lithium phosphate batteries. In the south, there are no obvious endurance anxiety and battery attenuation problems. In the north and central regions, endurance anxiety and battery attenuation will be more serious. 800,000 kilometers in 8 years is definitely useless. 300,000 kilometers can still be played; ternary lithium batteries can also be used. In summary, from the current point of view, CTP technology and blade batteries have their own advantages and disadvantages, but the overall blade battery is mainly lithium iron phosphate batteries, and the stability is relatively high. CTP technology needs to be evaluated

 

Compared with traditional power lithium batteries, blade batteries can increase the space utilization rate of battery packs and increase energy density. On the other hand, due to the larger heat dissipation area of the blade battery, more heat can be transmitted from the inside to the outside. It can match the "blade battery" with higher energy density launched by BYD, which belongs to; high output power, long battery life, and no toxic substances. The "blade battery" has the safety of other power batteries that cannot be compared, with long life and long battery life. The biggest advantage of lithium -ion batteries is that there is no memory effect. Even if it runs for a long time, the temperature range at running is relatively wide; BYD's blade battery has many advantages and disadvantages, and the advantages are the high safety factor. The blade released by BYD is relatively light weight and easy to use. Of course, it also has certain disadvantages. The main disadvantage is that the discharge performance is slightly poor at low temperature. The three major advantages of BYD blade batteries will push the electric vehicle industry to the blue ocean. In this project, "blade batteries" have achieved unexpected good results. Compared with the video of BYD's three battery acupuncture experiments within a week, under the test conditions of the same response, the three yuan; BYD's blade battery advantages are high safety and light weight. The disadvantage is poor low -temperature discharge performance. It is difficult to repair after the battery bump. Essence As an important global electric vehicle battery supplier, in order to seize the new energy battery market, BYD launched independently developed blade batteries. Although BYD launched a blade.
