固态电池，我国科学家取得重要突破

Core Viewpoint - Chinese scientists have made significant progress in the field of lithium battery polymer electrolytes, providing new ideas and technical support for the development of practical high-safety, high-energy-density solid-state lithium batteries [1][3] Group 1: Research Breakthrough - A team led by Professor Zhang Qiang from Tsinghua University has developed a novel fluorinated polyether electrolyte using a "rich anion solvation structure" design strategy [3] - The new electrolyte enhances physical contact and ionic conductivity at the solid-solid interface, significantly improving the high-voltage performance and interface stability of lithium batteries [3] Group 2: Performance Metrics - A polymer soft-pack full battery constructed with the new electrolyte achieved an energy density of 604 Wh/kg under 1 MPa external pressure, surpassing current commercial batteries [3] - The battery successfully passed safety tests, including puncture and exposure to a 120°C heat chamber for 6 hours, without any incidents of combustion or explosion [3] Group 3: Future Implications - The research findings are expected to provide important technical references for the development of mature solid-state battery products in the future [3]
