重磅！固态电池两大关键突破，新华社连发报道

Core Viewpoint - Recent breakthroughs in all-solid-state lithium battery interface technology by Chinese researchers provide solid support for the practical application of this next-generation energy storage technology [1][5]. Group 1: Research Breakthroughs - A research team led by Huang Xuejie, in collaboration with Huazhong University of Science and Technology and the Ningbo Institute of Materials Technology and Engineering, developed an anion regulation technology that addresses the challenge of tight contact between the electrolyte and lithium electrode in all-solid-state lithium batteries [5]. - The introduction of iodine ions into the electrolyte allows for the formation of an iodine-rich interface that actively attracts lithium ions, filling gaps and ensuring a tight fit between the electrode and electrolyte [6]. - The prototype batteries created using this technology demonstrated stable performance after hundreds of charge-discharge cycles, significantly surpassing existing similar batteries [6]. Group 2: Material Innovations - A research team from the Chinese Academy of Sciences has made advancements in solid-state lithium batteries, providing new pathways to address high interface impedance and low ionic transport efficiency [7]. - The team designed a new material that integrates ion-conducting ethoxy groups and electrochemically active short sulfur chains, achieving interface integration at the molecular level [8]. - This new material exhibits high ionic transport capability and allows for controllable switching of ionic transport and storage behavior across different potential ranges, enhancing the energy density of composite cathodes by up to 86% [8].
