# Ultra-Fast Solid-State Batteries Chinese Academy of Sciences Unveiled Its Lithium-Metal Pouch Cell By Adam Harrie | Written with AI assistance | Published 2026-05-29 | Autos Source: Trend Hunter, https://www.trendhunter.com/trends/lithium-metal-pouch-cell References: [digitaltrends](https://www.digitaltrends.com/cars/chinese-researchers-claim-solid-state-ev-battery-can-charge-in-just-minutes/)  Researchers at the Chinese Academy of Sciences developed a prototype [solid-state lithium-metal pouch cell](https://www.trendhunter.com/trends/cell-battery-design) designed to combine [ultra-fast charging](https://www.trendhunter.com/trends/ultrafast-charging-systems) with high energy density, reporting performance of 451.5 Wh/kg in laboratory testing. Published in the Journal of the American Chemical Society, the research described stable cycling across 700 charge cycles under a 20C charging rate, a level that theoretically enables charging in roughly three minutes. The prototype also underwent nail-penetration testing as part of laboratory safety validation and was presented as a potential solution to longstanding trade-offs between charging speed, energy density and stability in electric-vehicle batteries. The work arrives amid intensified competition in [solid-state battery development](https://www.trendhunter.com/trends/quantumscape), particularly among Chinese automakers and battery suppliers pursuing faster charging architectures and higher-capacity chemistries. If commercialized successfully, the technology could significantly reduce EV charging times while extending driving range, increasing pressure on automakers and infrastructure providers to improve thermal management and high-speed charging systems.
