BYD Is Moving Away From Lithium Batteries to Focus on Blade Batteries, Which Can Offer More Safety for Electric Cars and 50% More Efficiency.
Due to its optimized battery structure, BYD stated that the use of Blade Battery is also 50% greater compared to previous products, with its range reaching the same level as ternary lithium batteries. The Blade Battery for electric cars from the Chinese company is produced at BYD’s FinDreams battery unit, located in the Bishan district of Chongqing, China.
BYD Claims Blade Battery Occupies 60% of Package Volume
The almost 1-meter-long battery can achieve tolerances of +/- 0.3 mm, and the speed and precision of the lamination of a single piece has an efficiency of 0.3 s/pieces. This type of lamination stems from the independent development of the Chinese company of electric cars and its cutting-edge technologies, which cannot be copied.
During nail penetration tests, the new component emitted no smoke or fire, and its surface temperature reached a maximum of 60 ºC.

Under the same conditions, the lithium battery exceeded 500 ºC and burned instantly. Thus, electric cars equipped with the new Blade Battery would be much less susceptible to fires when severely damaged.
Why Hasn’t Tesla Acquired the New Technology Yet?
Although it is already testing the new technology, Tesla is still using thousands of tiny cylindrical battery cells to assemble its complex lithium battery. This is because when the automaker launched the Roadster in 2008, high energy density battery cells were only available in this format.
Only in 2016 did high-density batteries start to be available in pouch format. The first electric car to use the Blade Battery is the BYD Han, which is already sold in Brazil. The 65 kWh battery provides a range of 506 km for the vehicle.
Is BYD Han a Better Alternative than Tesla Model S?
The BYD Han, which can go from 0-100 km/h in just 3.9 seconds, has a cobalt-free Blade Battery that helps it to be a great electric car and, so far, a better alternative to the Tesla Model S.
However, it is important to highlight that Tesla’s billionaire Elon Musk is already working on a new diamond-based battery and nuclear energy that may last much longer than the vehicle itself.
