Huawei patents a new solid-state battery with 1,860 miles range

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. Huawei boasts between 400 and 500 Wh/kg energy density, between two and three times more than the currently available lithium-ion 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.

All of this sounds nice in theory, but it's still a theory at this point. Even the figures Huawei cites are theoretical, and it will likely take years before reaching such a range and charging rate. Not to mention, there's no infrastructure that can accommodate such fast-charging solid-state cells.

One thing is for sure, China is trying to become a world leader in solid-state battery production, as more than 36% of the solid-state battery patents filed annually come from China.
