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 patented solid-state battery push EV limits?

Huawei’s patented solid-state battery promises 3,000 km range & 5-min charging, pushing EV limits — but real-world hurdles remain.

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 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.

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.

Should Huawei be able to nail a 400 Wh/kg energy density?

Should Huawei be able to nail energy densities between 400 and 500 Wh/kg, it would be far better placed producing smaller packs that can still offer an impressive range without the need for enormous, expensive batteries.
