Still, Huawei’s 3,000 km solid-state battery patent is an exciting development in EV technology. Its claims of high energy density and ultra-fast charging, if proven at scale, could greatly change how EVs are built, charged, and used. While challenges remain, this innovation reflects the growing pace of change in clean transport.
Huawei’s patent focuses on a few key improvements that address common problems in solid-state battery development, including: This gives the battery a much longer driving range. Under China’s CLTC test cycle, the range reaches 3,000 km. Under the stricter U.S. EPA test, it would still exceed 2,000 km, well beyond most current EV models.
Huawei’s entry into the EV battery market adds momentum to an already competitive space. Its solid-state battery offers up to 500 Wh/kg in energy density and charges in just five minutes. This could set new industry standards and urge competitors to accelerate their development.
This recent patent application, reported by CarNewsChina, signals Huawei’s aim to disrupt the booming solid-state battery sector. The patent details a battery with an energy density of 400 to 500 Wh/kg, potentially tripling that of standard lithium-ion cells. Huawei’s tech tackles a key challenge: electrochemical stability.
Huawei’s breakthrough is based on a nitrogen-doped sulfide solid-state battery, which claims to reach energy densities between 400 and 500 watt-hours per kilogram (Wh/kg). That’s about 2 to 3 times more than the energy density of most current lithium-ion EV 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.
