Huawei Patents 3,000km Solid-State Battery with 5-Minute
Huawei has intensified its ambitions in advanced energy storage by patenting a sulfide-based solid-state battery capable of achieving driving ranges of up to 3,000 kilometres
US survey reveals a messy mystery Huawei has filed a patent detailing a sulfide-based solid-state battery design with energy densities between 180 and 225 Wh/lb, roughly two to three times higher than today's typical electric vehicle batteries.
Huawei's engagement in solid-state battery research reflects a wider trend among Chinese technology and automotive companies. Although Huawei does not manufacture power batteries directly, its growing interest in upstream battery materials is notable.
To enable this seismic shift in transportation, Huawei launched its Intelligent Automotive Solution business unit in May 2019. We invest about US$1 billion annually in research and development related to autonomous driving technologies. Autonomous vehicles will produce broad social benefits:
Although Huawei does not manufacture power batteries directly, its growing interest in upstream battery materials is notable. Earlier in 2025, the company submitted another patent focused on synthesizing sulfide electrolytes—a vital component known for its high conductivity but also high costs, sometimes exceeding the price of gold.
