Electric cars with HUAWEI's new battery will be able to travel 3,000 kilometers

HUAWEI has filed a patent for a new solid-state battery architecture for electric vehicles with a claimed energy density of 400 to 500 Wh/kg - several times higher than today's lithium-ion batteries. According to the company's calculations, such batteries can provide a range of up to 3,000 kilometers and fast charging from 10 to 80% in less than five minutes.

The technology is based on the use of nitrogen-doped sulfide electrolytes, which should reduce chemical side reactions and improve battery stability. HUAWEI is keeping the rest of the details under wraps. Unlike some automakers, the company does not produce its own cars, but is actively deploying its technology in cooperation with other brands.

Despite the ambitious claims, industry experts assess the innovation with caution. Yang Min-ho, a professor of energy engineering at Dankook University, noted that such characteristics are only achievable in laboratory conditions. Scaling such technology for mass production is a much more difficult task because of heat management and stability issues.

HUAWEI's development is part of a global race to commercialize solid-state batteries. China is actively promoting its developments in this area, but the timing and efficiency of actual implementation remain unclear.
