What is BYD's "Blade Battery"? What advantages does it have over ordinary power batteries?

Recently, BYD released the "blade battery", which has generated a large response in the industry, while the share price also rose significantly. So what is BYD's "blade battery" and what advantages does it have over traditional power batteries?

Recently, BYD Chairman Wang Chuanfu announced that BYD's "blade battery" will start mass production in March at its Chongqing plant, and will be carried for the first time in the BYD Han EV, which will be launched in June. Once the news came out, the capital market immediately reacted, BYD stock once stopped. The so-called "blade battery" is actually BYD's new generation of lithium iron phosphate batteries, also known as lithium iron phosphate super battery. The reason why the name "blade battery", mainly because of the layout of the electric core is like a "blade" as inserted into the battery pack, and the traditional power battery cell is different.

Traditional power battery cells use a cylindrical design, and are packaged into a battery pack to form a battery pack. However, the "Blade Battery" uses a large battery cell with a length of more than 0.6 meters, which can be directly integrated into a battery pack without a module (CTP technology). Compared with the traditional power battery, "blade battery" can improve the space utilization of the battery pack and increase the energy density. On the other hand, because the cells of the "blade battery" have a larger heat dissipation area, more heat can be transferred from the inside to the outside, which can match the higher energy density.

For BYD, the "blade battery" also has a deeper strategic significance. Lithium iron phosphate batteries have an inherent disadvantage in terms of energy density compared to lithium ternary batteries, which is one of the reasons why lithium ternary batteries are becoming more and more popular. But compared to the ternary lithium battery, lithium iron phosphate battery has high security, long service life and other advantages. Now the "blade battery" effectively weakened the low energy density of lithium iron phosphate battery shortcomings, the future prospects for application will be more broad. For BYD, lithium iron phosphate batteries are its strengths, "blade battery" makes it like a tiger with wings.

BYD's "razor blade battery" is very helpful in improving the energy density of lithium iron phosphate batteries, while lithium iron phosphate batteries are more stable and durable than lithium ternary batteries, the future prospects for applications are quite broad.
