Huawei has filed a patent for a solid-state battery with a claimed range of 3,000 kilometers and a 5-minute charging time. The technology uses nitrogen-doped sulfide electrolytes to enhance stability and longevity. While promising, experts caution that these figures are theoretical and require currently unavailable charging infrastructure.
Many companies are pursuing solid-state battery technology, with Toyota aiming for implementation by 2028 and some Chinese brands already testing them. Scaling production remains a significant hurdle.
Chinese companies hold a significant share of global solid-state battery patents (36.7%). Government investment and the involvement of tech giants like Huawei and Xiaomi highlight China's growing influence in this sector. This increased activity has raised concerns among Japanese and South Korean competitors.
The practical realization of Huawei's claims faces significant challenges. The required charging infrastructure is not yet commercially available. Despite these challenges, Huawei's patent signals a significant advancement in solid-state battery technology and reinforces China's position in the global battery market.
