The Chinese company Svolt Energy has just introduced a new battery that will allow more than 1000 km of autonomy on a single charge. It is scheduled to arrive in the first production cars next year. Another company, EVE, also presented its battery with a range of 1000 km and a charge in less than 10 minutes.
Even if the race for autonomy is actually no longer a problem for many manufacturers, as some electric cars today also create an autonomy similar to that of a thermal model, the specter of fuel shortages lurks in the minds of customers, especially if result of a loading . network which is sometimes still unstable. Zeekr 001 and Nio ET7 are said to be the first electric cars with a range of 1000 km.
Regardless, the range of an electric car remains one of the main selling points for an electric car. Battery manufacturers have realized this well, and Svolt Energy, one of the leading manufacturers of batteries for electric cars, announced at the third "Battery Day" event, which will be held on April 15 in Changzhou, China.
FROM 800 TO MORE THAN 1000 KM AUTONOMY DEPENDING ON THE TECHNOLOGY
The Dragon Armor Pack, which contains lithium iron phosphate (LFP) cells, benefits from an improved volumetric efficiency of 76%, allowing electric cars a range of around 800 km.
The Dragon armor suit with high manganese-iron-nickel cells (H-LMFP) can achieve a range of more than 900 kilometers, while nickel-manganese-cobalt (NMC) batteries have a battery life of more than 1,000 kilometers according to the manufacturer can reach . These batteries can now be ordered from interested manufacturers.
However, please note that the autonomy will be announced in the Chinese CLTC cycle, which is more optimistic than the European WLTP cycle. You will have to remove 10 to 15% of the autonomy, which will give about 850 km for the battery with the largest capacity.

Therefore, we should get these batteries in the first production vehicles from the end of 2023, especially an SUV and a coupe that will go into production from October 2023. But the company has not provided any further information about these two models.
These new battery packs also feature some cool innovations. In fact, a new Chinese regulation requires that the battery not catch fire within five minutes in the event of thermal runaway. There fore, Dragon armor can ensure that heat leakage in one cell does not spread to neighboring cells. Which certainly avoids some long and stubborn fires.
The battery can be charged in less than 10 minutes
In addition to Svolt Energy, another battery manufacturer has just launched new products. EVE Lithium Energy (probably a BMW supplier) recently introduced new large cylindrical batteries with an energy density of 350 Wh/kg that can be charged to 100% in nine minutes with an ultra-fast charging solution.
Depending on the capacity of the battery pack, this technology can give an electric car a range of 500 to 1,000 km on a single charge, always on the CLTC cycle. The manufacturer says only 10% wear after loads at 10 °C (eg at 1000 kW for a 100 kWh battery) and 20% wear after 2500 cycles. The battery can be used down to -40 °C.

The transition to cylindrical batteries is slowly but surely becoming more democratic. Tesla has been using this solution for several years in its Model 3 (excluding the Propulsion model), Model Y, Model S and Model X. CATL will soon announce new cylindrical batteries that will eventually replace pocket batteries.
Cylindrical batteries allow greater flexibility in the design of electric cars, with a better cooling system and the ability to maintain high power for both driving and charging.
