At present, there are mainly two kinds of automobile batteries, one is ternary lithium battery, and the other is lithium iron phosphate battery, which is also called "blade battery". Both batteries have their own advantages. The former has high power and excellent battery life, while the latter has high safety and long life.
BYD has built a "blade battery" with high endurance, high safety and long life. With more than 300 core patents, the volume energy density and weight energy density have been greatly improved. Therefore, when the test video of its acupuncture temperature of 30 degrees came out, it attracted many controversies in the industry. Compared with ternary lithium batteries, lithium iron phosphate batteries are more complete, with longer service life and lower manufacturing cost. Its runaway temperature is above 600 degrees, which is much higher than that of ternary lithium, and even its charge and discharge cycles are much higher than that of ternary lithium. After reaching 3500 times, the battery began to decay. No wonder there are doubts in the industry, but the time to uncover the truth is coming. If the "blade battery" is really so excellent, then the electric vehicle industry will be in great turmoil.
