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.

Why is Huawei pursuing solid-state battery development?

By pursuing solid-state battery development, Huawei joins a growing list of global automakers and tech companies such as BMW, Mercedes-Benz, Volkswagen, and BYD, all racing to unlock safer, lighter, and faster-charging batteries to transform the future of electric mobility.

What is Huawei's new solid-state battery patent?

Huawei’s recent announcement of its solid-state battery patent is a significant milestone. Filed in June 2025, this patent promises a battery capable of delivering a staggering 1,864 miles on a single five-minute charge. This advancement is attributed to an energy density between 400 and 500 Wh/kg, nearly double that of current batteries.

Is Huawei a good battery company?

If these claims are accurate, Huawei would have a huge advantage in energy density and charging speed compared to other automakers and tech companies that are researching solid-state batteries. Assuming everything shakes out, SynergyFiles.com points out this could spell trouble for rival companies.

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 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.
