Is Huawei developing a solid-state battery?

According to the patent, Huawei is developing a solid-state battery architecture with an energy density between 400 and 500 Wh/kg—reportedly three times higher than that of conventional lithium-ion cells used in today’s electric vehicles.

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.

What is Huawei's big battery breakthrough?

Huawei’s huge battery breakthrough! New solid state tech promises massive range and miniscule charging times Smartphone giant and EV investor Huawei has challenged CATL and BYD’s supremacy by inventing a pioneering new battery that blends an incredible range of up to 3000km with a charging time of just five minutes.

Does Huawei make power batteries?

Although Huawei does not manufacture power batteries directly, its growing interest in upstream battery materials is notable. Earlier in 2025, the company submitted another patent focused on synthesizing sulfide electrolytes—a vital component known for its high conductivity but also high costs, sometimes exceeding the price of gold.

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.

Could a new battery pack solve a major problem?

Additionally, the company claims that this new battery pack may have solved a major issue that the current battery packs have. In the filed patent, Huawei notes that by doping sulfide electrolytes with nitrogen, the company is developing a battery pack with enhanced electrochemical stability, improved safety and reduced degradation.
