成功开发！我国团队突破锂电池领域关键技术瓶颈

Core Insights - A research team from the Chinese Academy of Sciences has developed an anion regulation technology that creates a new interface between the electrode and electrolyte, overcoming a significant bottleneck in the practical application of all-solid-state batteries [1][3] - All-solid-state lithium batteries are considered the "holy grail" of next-generation energy storage technology, but have faced challenges due to the need for tight contact between the solid electrolyte and lithium electrode, traditionally requiring heavy external pressure [1][3] Group 1 - The research identified that the contact between the lithium electrode and electrolyte in all-solid-state batteries is suboptimal, with numerous micro-pores and cracks that can shorten battery life and pose safety risks [3] - The new technology involves introducing iodine ions into the sulfide electrolyte, which migrate to the electrode interface under an electric field, forming an iodine-rich interface that actively attracts lithium ions and self-repairs gaps and pores [3] - Prototype batteries made using this technology have shown stable and superior performance after hundreds of charge-discharge cycles under standard testing conditions, significantly exceeding the performance of existing similar batteries [3]
