BYD's blade battery is called super lithium iron phosphate battery, which uses new technology in the battery structure design. The main feature of the blade battery is the flat design of the battery cell, which can be up to 2500mm in length, thus increasing the volumetric energy density by 50%. Moreover, the battery life of the vehicle can reach more than 8 years and 1.2 million kilometers. Most importantly, the cost of new products may be reduced by 20 to 30%. BYD Blade Battery is the "super lithium iron phosphate battery" that BYD has developed for many years. The blade battery is not a breakthrough in materials, because the material remains the same as lithium iron phosphate. It is just an innovation in the battery structure design. The single energy density has not been improved, but it has been changed to a larger package. BYD itself said that the battery has been incubated and built for a long time and currently has more than 300 core patents.
