On March 29, BYD's "Blade Battery" was officially launched. "Blade battery" is another innovation of BYD based on lithium ferrophosphate technology. Its volumetric energy density is the same as that of mainstream ternary lithium batteries, and it also has the characteristics of high safety, long service life and long battery life.

At the press conference, Wang Chuanfu, Chairman and President of BYD Group, said that in the field of new energy passenger cars, many companies are caught in the comparison of mileage. The pressure generated by this comparison will be passed on to the power battery, which will cause the automotive industry to make an irrational pursuit of the "energy density" of the power battery.

Mr. Wang further stated: “The Blade Battery is guiding the global battery industry back on track, putting an end to the spontaneous combustions in NEVs..

In nail penetration tests, the Blade Battery did not smoke or catch fire and its surface temperature never exceeded 60° C. Under the same conditions, a ternary lithium battery exceeded 500°C and burned violently, while a conventional lithium iron phosphate battery reached dangerously high temperatures of up to 400°C.

Developed by BYD over the past several years, the cells in the Blade Battery can be arranged in such a way as to increase the space utilization in a battery pack by 50% compared to conventional lithium iron phosphate batteries.

The first BYD model to use the Blade Battery will be the Han, which is scheduled to go on sale in June. It will be the star of BYD’s Dynasty lineup, boasting a cruising range of 605 kilometers and acceleration of 0 to 100 km/h in just 3.9 seconds.

“Today, many vehicle brands are in discussion with us about partnerships based on the technology of the Blade Battery,” says He Long, vice president of BYD and chairman of the FinDreams Battery sub-brand. He adds that BYD will gladly share and work with global partners to achieve mutually beneficial outcomes for all industry players.
