Huawei's 3000km Range Solid-State Battery Patent Shakes Up the EV Market

Huawei has filed a patent for a sulfide-based solid-state battery boasting a 3,000km range and 5-minute ultra-fast charging. This breakthrough signals Huawei's ambitious entry into the rapidly evolving solid-state battery landscape and could reshape the electric vehicle market. The patent describes a battery with energy densities of 400-500 Wh/kg, two to three times that of conventional lithium-ion cells. Huawei's innovation lies in improving electrochemical stability by nitrogen-doping the sulfide electrolyte, addressing a major hurdle for sulfide-based battery commercialization. While the 3,000km range and 5-minute charge remain theoretical, the technology showcases China's accelerating lead in next-generation battery technology, sparking concern and attention from global competitors.
