What is Huawei's new EV battery?

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.

Will Huawei's 3,000 km solid-state battery patent change EV technology?

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.

Does Huawei make power batteries?

While Huawei does not manufacture power batteries, it has shown increasing interest in upstream battery materials. Earlier in 2025, the company filed a separate patent on the synthesis of sulfide electrolytes — a key material known for its high conductivity but also high cost, sometimes exceeding the price of gold.

Why is Huawei pursuing solid-state battery research?

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.

Does Huawei have a sulfide battery?

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 and ultra-fast charging in just five minutes.

Does Huawei have a 3,000-kilometre range and 5-minute charging capacity?

While Huawei’s assertions of a 3,000-kilometre range and five-minute charging have attracted significant attention, experts caution that such figures remain theoretical and would necessitate charging infrastructure that is currently not commercially available.
