Core Viewpoint - Solid-state batteries represent a core technological direction for next-generation lithium batteries, with significant application prospects in fields such as new energy vehicles and low-altitude economy. Recent advancements by Chinese scientists have overcome critical challenges, enabling a leap in solid-state battery performance, potentially allowing for over 1000 kilometers of range with a 100-kilogram battery, compared to the previous maximum of 500 kilometers [1][2]. Group 1: Challenges in Solid-State Batteries - The primary challenge in solid-state batteries lies in the interaction between lithium ions and the solid electrolyte, where the solid electrolyte's high hardness and brittleness create inefficiencies in charge and discharge processes [2][4]. - The interface between the solid electrolyte and the lithium metal anode is problematic, resembling a poorly adhered combination of hard and soft materials, which affects battery efficiency [2][4]. Group 2: Key Technological Breakthroughs - Three major technological breakthroughs have been achieved, addressing the interface issues between the solid electrolyte and lithium anode, thereby enhancing the battery's range [4]. - A "special glue" developed by the Chinese Academy of Sciences helps to fill gaps at the interface, allowing for better contact and efficiency in solid-state batteries [6]. - A flexible framework created using polymer materials enhances the electrolyte's durability, allowing it to withstand significant deformation while improving lithium ion mobility and increasing energy storage capacity by 86% [8]. - A fluorinated polymer modification provides high voltage resistance, ensuring safety and performance under extreme conditions, such as puncture tests and high temperatures [10].
