Chinese tech powerhouse announces 1,800-mile electric vehicle battery with solid-state design and files corresponding patent application
As the world continues to transition towards electric mobility, Huawei is making significant strides in the development of advanced solid-state batteries. These batteries could potentially revolutionise the electric vehicle (EV) industry, offering unprecedented ranges and rapid charging times.
According to recent reports, Huawei's solid-state batteries are based on nitrogen-doped sulfide solid electrolytes, which provide 2-3 times higher energy density (400-500 Wh/kg) than typical lithium-ion batteries. This could mean electric vehicles travelling around 1,800 to 1,864 miles (approximately 3,000 km) on a single charge and recharging in about five minutes. However, it's important to note that commercialization is still several years away due to manufacturing scale challenges and the need for extensive testing.
China, being a global leader in the electric vehicle market, is eager to showcase innovations that could reshape the industry. Huawei's solid-state battery technology, if successfully developed, could be a significant contribution to this endeavour.
Meanwhile, other global automakers and tech companies like BMW, Mercedes-Benz, Volkswagen, and BYD are also actively researching solid-state batteries. BMW and Volkswagen have been aiming for commercialization timelines around the late 2020s to early 2030s, while Mercedes-Benz is focusing on improving energy density and safety to enhance its EV lineup. BYD, a major Chinese EV and battery manufacturer, continues to invest heavily in battery R&D, predominantly progressing with lithium iron phosphate (LFP) and lithium-ion chemistries.
The challenge for all these companies remains the difficulty and high cost of scaling solid-state battery manufacturing, along with the need for safety and longevity validation before mass-market deployment. Huawei's recent patent filings and public disclosures indicate a more aggressive push towards solid-state battery innovation, but commercial use is still years away even for Huawei.
In summary, Huawei's solid-state battery technology is a promising development that could significantly improve the range and charging speed of electric vehicles. While other global companies are also actively researching solid-state batteries, Huawei's progress appears to be particularly notable at this stage.
