Huawei’s New Solid-State Battery Tech Promises 3,000 km Range & 5-Min Full Charge

Huawei may not manufacture batteries, but it's diving deep into battery innovation. A newly revealed patent shows the company is working on a groundbreaking solid-state battery that could offer an astonishing 3,000 km range on a single charge and fully recharge in just five minutes.

The proposed battery boasts an energy density between 400 and 500 Wh/kg—that's 2 to 3 times higher than today’s best lithium-ion batteries. If realized, this would mark a massive leap for electric vehicles (EVs).

To tackle the well-known issues with solid-state tech, Huawei is using nitrogen-doped sulfide electrolytes. This approach boosts electrochemical stability, enhances safety, and reduces degradation—three of the main barriers holding back solid-state batteries from going mainstream.

However, it’s important to note that these are still theoretical figures. Huawei’s innovation is still in the research phase, and practical implementation—along with the required fast-charging infrastructure—may take years.

Still, the push is real: China is leading the global race, filing over 36% of the world’s solid-state battery patents every year.
