无需外部加压！我科学家解决全固态金属锂电池界面接触难题

Core Insights - A new anion regulation technology has been developed by a research team from the Chinese Academy of Sciences, which creates a novel interface between the electrode and electrolyte, allowing lithium ions to flow actively and fill gaps automatically, thus overcoming a major bottleneck in the practical application of all-solid-state batteries [1][2] Group 1: Technology Development - The research team introduced iodine ions into sulfide electrolytes, which move to the electrode interface under electric field influence, forming an iodine-rich interface that self-repairs and maintains tight contact between the electrode and electrolyte [2] - The prototype batteries made using this technology have shown stable and superior performance after hundreds of charge-discharge cycles under standard testing conditions, significantly surpassing existing similar batteries [2] Group 2: Industry Implications - This new design simplifies manufacturing and reduces material usage while enhancing battery durability, with potential energy densities exceeding 500 Wh/kg, which could double the battery life of electronic devices [2] - The breakthrough is expected to accelerate the development of high-energy-density all-solid-state lithium batteries, with applications anticipated in humanoid robots, electric aviation, and electric vehicles, providing safer and more efficient energy solutions [2]
