Huawei Patents 3,000km Solid-State Battery with 5-Minute Charge
Huawei’s patent filing describes a sulfide-based solid-state battery targeting higher energy density and reduced charging time
Huawei has stepped up its ambitions in advanced energy storage with a patent for a sulfide-based solid-state battery that offers driving ranges of up to 3,000 kilometres and ultra-fast charging in just five minutes. The filing also details a novel approach to improving electrochemical stability: doping sulfide electrolytes with nitrogen to address side reactions at the lithium interface, a long-standing obstacle to the commercialisation of sulfide-based batteries. If breakthroughs like this can be commercialised, they may help rewrite the rules of electric mobility, reducing range anxiety, slashing charge times, and enabling a new level of energy independence for automakers and tech firms alike.
