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 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.

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.

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.

How many miles can a Huawei battery charge?

Huawei promises that its battery technology could deliver around 1,864 miles of range and achieve a 10% to 80% charge in under five minutes.

Does Huawei use sulfide electrolytes?

Huawei’s patent application reveals that its battery uses a method of doping sulfide electrolytes with nitrogen to reduce side reactions at the lithium interface. However, beyond this detail, the company is keeping most of its technology under wraps as competition intensifies to safely mass-produce solid-state batteries.
