固态电池，新突破！

Core Insights - Solid-state batteries represent a key technological direction for next-generation lithium batteries, with significant application prospects in electric vehicles and low-altitude economy sectors. Recent advancements by Chinese scientists have led to a breakthrough in all-solid-state lithium batteries, potentially doubling the range from 500 kilometers to over 1000 kilometers with a 100-kilogram battery [1]. Group 1: Technical Challenges and Breakthroughs - The primary challenge in solid-state batteries lies in the interface between the hard, brittle sulfide solid electrolyte and the soft lithium metal anode, which affects charging and discharging efficiency [3][5]. - Multiple research teams in China have achieved three critical technological breakthroughs that address the contact issues at the solid-solid interface, thereby overcoming the range limitations of solid-state batteries [6]. Group 2: Key Technological Innovations - A "special glue" developed by the Chinese Academy of Sciences helps to fill gaps at the interface between the electrode and electrolyte, enhancing the contact and efficiency of lithium-ion transport [7]. - A flexible framework created using polymer materials allows the electrolyte to withstand significant deformation without damage, improving the battery's durability and increasing its energy storage capacity by 86% [9]. - A fluorinated polymer material has been used to enhance the electrolyte's resistance to high voltage, ensuring safety and performance under extreme conditions, such as puncture tests and high-temperature environments [11].
