Chinese technology giant and global leader in electric cars, BYD, announced the second generation of the battery, Blade V2. This new technology promises to be a major advance in terms of autonomy, performance and cost.
The revelation was made by BYD's CEO, Wang Chanfu, during a financial results meeting. The new battery, called Blade V2, is scheduled to be launched in August 2024. BYD, founded in 1995, initially manufactured rechargeable batteries for cell phones.
Since then, company became leader in the automotive, electronics, renewable energy and railway sectors. Among its most notable innovations is the Blade battery, first introduced in March 2020. These batteries are made from lithium iron phosphate (LFP), which eliminates the use of nickel, cobalt and manganese, materials common in other batteries. lithium ions.
LFP batteries have lower energy density than NMC (nickel-manganese-cobalt) batteries, but offer several advantages
They are cheaper, have a longer life cycle (up to 5.000 charge and discharge cycles) and a greater charging capacity. The Blade battery cell structure is made up of long, transversely aligned blades, optimizing space by more than 50% compared to conventional batteries.

Blade battery cells have wide surfaces that release and generate heat more slowly, helping with heat dissipation. Flat rectangular shape improves cooling and preheating performance. Additionally, the Blade battery does not release oxygen during thermal runaway, unlike NMC batteries, making it less susceptible to fires.
BYD has already subjected the Blade V2 battery to rigorous endurance testing
In a nail penetration test, the battery did not emit smoke or catch fire, reaching a temperature of 30 to 60 °C. In comparison, an NMC battery under the same conditions exceeded 500°C and caught fire instantly.
With the new generation of batteries, BYD's electric cars will be able to have a range of up to 1.000 km on a single charge. Energy density will be increased from 140 Wh/kg to 190 Wh/kg, a significant leap that will allow for this increase in autonomy.
Currently, BYD electric cars sold in Brazil have a range of between 350 and 400 km
The new Blade battery will enable a car interior more spacious, as it will take up less space. Additionally, smaller, lighter batteries mean less material used and lower production costs, which could make electric cars more affordable for consumers. The Blade V2 is scheduled to launch in August 2024, marking a significant step forward for BYD and the electric vehicle market.
Every innovation has setbacks in its beginning, I sincerely hope for a promising future for electric cars.
I don't understand; energy density 140, the new generation 190 (V2), means an increase in autonomy of almost 36%, example: current 400km, new 444km of autonomy. Have you found 1000km yet? (100% to 125%)
