Can BYD "Blade Battery" become the mainstream in the future?

With the increasing demand of users for the cruising range of new energy vehicles, major automobile companies are constantly developing new technologies to improve the energy density of power batteries. Recently, Wang Chuanfu, chairman of BYD, revealed at the China Electric Vehicle 100 Forum Committee that BYD has developed a new type of "blade battery", which can greatly improve the energy density compared with traditional batteries and has great advantages in safety. So what is the magic of this "blade battery" launched by BYD? Can it become the mainstream of future development?

First of all, the so-called "blade battery" is just a name announced by BYD, and its essence is lithium iron phosphate battery. Lithium iron phosphate batteries have been replaced by ternary lithium batteries because of their low energy density, and most models on the market are equipped with ternary lithium batteries. But in fact, from the perspective of service life and safety, lithium iron phosphate battery has great advantages. As a loyal supporter of lithium iron phosphate battery, BYD has never given up research and development because of the low energy density of lithium iron phosphate battery. The latest "blade battery" mainly uses the corresponding technology to develop single batteries with a length of more than 0.6 meters, and then inserts the batteries into the battery pack in an array, thus improving the space utilization rate and energy density of the power battery pack.

Secondly, this modular-free direct integration technology adopted by BYD is also called CTP technology. Compared with the traditional battery module production mode, it can save the link of battery module assembly, which not only reduces the use of parts and components, reduces the production cost, but also improves the volume utilization rate and production efficiency of battery pack. On this basis, the "blade battery" can also ensure that each single battery can obtain a large enough heat dissipation area, match a stronger energy density, and the safety can be guaranteed to a certain extent. Most importantly, due to the use of lithium ferrous phosphate, the service life of the battery will be greatly improved, and the attenuation problem of the power battery will also be solved.

Finally, there is still a lot of controversy about BYD's blade battery. Even some media believe that BYD has not carried out a battery revolution in materials, but only made some changes in physical structure. Even if the energy density of the battery can be improved, the problem cannot be fundamentally solved. Of course, in response to such doubts, BYD officials also responded, saying that a technical analysis meeting will be held in March this year to discuss the application of power batteries with all sectors of society.

To sum up, the launch of "Blade Battery" really represents BYD's technological progress, with great market potential and development space. Of course, judging whether such a product can lead the future trend still needs the test of consumers and the market.
