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.

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

While Huawei’s claims of a 3,000-kilometre range and five-minute charging have generated widespread attention, experts warn that such figures remain theoretical and would require charging infrastructure that is not yet commercially available.

What challenges does Huawei's new battery face?

Huawei’s new battery faces several key challenges: High cost: Sulfide electrolytes used in this design are currently very expensive—up to $1,400 per kilowatt-hour (kWh), and in some cases more expensive than gold by weight. This limits affordability for mass-market EVs.

What does Huawei's patent mean for EV battery development?

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.

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.

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.
