Will Huawei's new battery improve energy storage?

In an effort to improve its energy storage, Huawei has submitted a patent application for a battery with a 3,000-kilometre range and a five-minute charging time. Compared to traditional lithium-ion cells, the new sulphide-based solid-state battery will have energy densities between 400 and 500 Wh/kg, or two to three times higher.

Does Huawei make batteries?

Even though Huawei doesn't manufacture batteries, the company is putting plenty of R&D resources into developing a new solid-state battery tech. The newest patent reveals a battery pack that can go for 1,860 miles away from the plug and fully charge in just five minutes. This is perhaps one of the craziest technologies we've heard so far.

How much does a Huawei battery cost?

Furthermore, the high production costs, which are currently between 8,000 and 10,000 yuan per kWh (about 1,100–1,400 USD), often prevent mass-market adoption. Huawei patents solid-state battery with 3,000 km range and 5-minute charge, promising breakthrough energy density and fast charging.

Can Huawei solve problems with solid-state batteries?

Additionally, the company has potentially solved some glaring issues with solid-state batteries. By doping sulfide electrolytes with nitrogen, Huawei improves electrochemical stability and safety and significantly slows down degradation, two of the biggest hurdles keeping solid-state tech from commercialization.

Does Huawei make upstream batteries?

Huawei has shown an increasing interest in upstream battery components even though it does not produce power batteries. Earlier in 2025, the company filed a separate patent application for the manufacturing of sulphide electrolytes, a vital material that is costly and sometimes more costly than gold because of its strong conductivity.

What is a battery energy storage system?

Battery Energy Storage Systems (BESS) have become a cornerstone technology in the pursuit of sustainable and efficient energy solutions. This detailed guide offers an extensive exploration of BESS, beginning with the fundamentals of these systems and advancing to a thorough examination of their operational mechanisms.
