Chinese researchers have achieved a breakthrough in solid-state battery technology, potentially changing the future of electric vehicles.The discovery comes as China continues to lead the global lithium battery race. Japan and South Korea remain strong competitors, but China pushes ahead.Solid-state batteries promise better energy storage and safety. However, overcoming technical challenges remains critical for mass adoption.
Traditional batteries use liquid electrolytes, but solid-state batteries rely on solid electrolytes. These materials cannot handle lithium expansion during charging cycles.As lithium expands and contracts, stress builds within the battery. This can lead to cracks or dendrites, which trigger short circuits.
Researchers from Tongji University and Huazhong University of Science and Technology tackled this issue. They studied the fatigue of lithium metal anodes.Their study revealed that the metal weakens over time, much like a paperclip bends repeatedly until it snaps.This research, published in Science, outlines how mechanical fatigue affects solid-state battery performance. It also allows scientists to predict battery life.Experts say this insight opens new directions for creating longer-lasting, safer batteries. Two U.S. scientists praised the study’s importance.
China’s focus on battery research keeps strengthening its industrial advantage. These findings may help the nation lead the next battery revolution. Solid-state batteries offer many benefits. They store more energy per kilogram—up to 500 Wh—compared to 300 Wh in regular batteries.They also reduce fire risks since they avoid flammable liquid components. This makes them safer for consumers and manufacturers.
Top Chinese companies, including CATL and BYD, aim to begin small-scale production by 2027. They believe commercial use will begin around 2030.Major partnerships are forming to speed up progress. BYD and the Shenzhen Institute of Advanced Technology are already working together.Solid-state battery development now moves faster than ever, driven by both scientific research and industry collaboration. China’s market scale, supply chain, and research force give it a unique advantage. Experts express confidence in China’s roadmap.
