东风350Wh/kg固态电池明年9月量产上车 续航达到1000公里

Core Viewpoint - Dongfeng Motor has established a pilot line for solid-state batteries with a capacity of 0.2GWh, aiming to mass-produce a solid-state battery with an energy density of 350Wh/kg by September 2026, which will enable vehicles to achieve a range of over 1000 kilometers [1][3] Group 1 - The new generation of fully autonomous high-energy solid-state batteries developed by Dongfeng utilizes a multi-component system with high-capacity ternary positive electrodes, silicon-carbon negative electrodes, and oxide polymer composite solid electrolytes, achieving an energy density of 350Wh/kg [3] - The solid-state battery maintains a 72% energy retention rate in extreme cold environments at -30℃ and supports ultra-fast charging, allowing 80% charge in just 10 minutes [3] - The battery has passed safety tests, including a 170℃ thermal safety test and GB38031-2020 compliance tests, demonstrating excellent thermal stability and safety, capable of withstanding punctures and significant deformations without combustion or explosion [3] Group 2 - Dongfeng plans to develop a fast-charging version of the 350Wh/kg solid-state battery, with pilot applications expected by December 2027, while also conducting preliminary research on a sulfide solid-state battery with an energy density of 500Wh/kg [3]
