Stellantis has just marked a major turning point in the electric vehicle industry with the development of a revolutionary battery with an energy density of 375 Wh/kg, surpassing Tesla’s current performance. This technological breakthrough promises to transform the automotive landscape by offering increased autonomy and unprecedented energy efficiency.
As the race for innovation intensifies, this new breakthrough positions Stellantis as an essential leader in sustainable technologies. Find out how this innovation could redefine industry standards and influence consumer choices in the years to come.
Partnership and technological advances
Automotive giant Stellantis has teamed up with start-up Factorial Energy to develop a new semi-solid battery. The aim of the partnership is to validate this innovative technology, which promises superior performance to traditional lithium-ion batteries. The semi-solid battery uses a stable gel material, offering an energy density of 375 Wh/kg, well above current standards. The result is extended range without weighing down the vehicle.
What’s more, it recharges quickly, reaching 90% in just 18 minutes. Tested on models such as the Dodge Charger Daytona and Mercedes-Benz EQS, this battery could revolutionize the electric vehicle market, thanks to its advantages in terms of safety, weight and cold-weather performance.
Technical specifications and performance
The semi-solid battery from Stellantis boasts an impressive energy density of 375 Wh/kg, surpassing conventional lithium-ion batteries which range from 200 to 300 Wh/kg. This breakthrough enables electric vehicles to achieve significantly greater range without compromising on weight. In terms of charging speed, the new technology enables the battery to go from 15% to 90% in around 18 minutes at room temperature, a major advantage for users.
In addition, it operates efficiently in a temperature range from -30°C to 45°C, offering better cold-weather performance compared with traditional cells. These features promise to improve the efficiency and range of electric vehicles, while enhancing their competitiveness on the market.
Production challenges and economic prospects
Mass production of these semi-solid batteries poses notable challenges, not least because of their current cost, estimated at 10 to 30 times that of conventional lithium-ion batteries. However, large-scale manufacturing could significantly reduce these costs, especially with strategic partnerships, notably with Chinese companies.
By reducing vehicle weight from 500 to 2,000 pounds with this technology, potential savings on manufacturing costs could reach between $2,500 and $10,000 per vehicle. This breakthrough could transform the automotive industry, making electric vehicles more affordable and efficient, while addressing current concerns about range and safety.
