604Wh/kg！固态电池，我国科学家再获重要突破

Group 1 - Tsinghua University team led by Professor Zhang Qiang has made significant progress in polymer electrolytes for lithium batteries, providing new ideas and technical support for the development of practical high-safety, high-energy-density solid-state lithium batteries [2][3] - The team proposed a "rich anion solvation structure" design strategy, successfully developing a new fluorinated polyether electrolyte that enhances solid-state interface physical contact and ionic conductivity, significantly improving lithium battery high-voltage performance and interface stability [3] - A polymer soft-pack full battery using this electrolyte achieved an energy density of 604Wh/kg under 1MPa external pressure, surpassing current commercial batteries, and demonstrated excellent safety performance in puncture and thermal tests [3] Group 2 - Tianjin University team introduced a "delocalization" design concept for high-energy lithium battery electrolytes, breaking the reliance on dominant solvation structures, leading to improvements in energy density and overall performance [4] - The team is actively promoting the technical transformation and application verification of their results, having established a pilot production line for high-energy lithium batteries, which have been successfully applied in three models of micro unmanned aerial vehicles, increasing endurance by 2.8 times compared to existing batteries [4] - Solid-state batteries are accelerating from laboratory research to industrialization, with significant policy support and market demand driving the global solid-state battery industry towards commercialization [4]
