讲座摘要：
Lithium bonds, analogous to hydrogen bonds, exhibit unique properties due to lithium’s weak metallic nature, offering exciting potential for lithium battery applications. This talk will delve into the concept of lithium bonds, exploring their underlying chemistry and how they can be harnessed to design new battery material combing with emerging artificial intelligence and further improve battery performances. Specifically, solid electrolytes combined with high-voltage Li-rich Mn-based cathodes and anode-free cell designs hold significant promise for high-energy-density and high-safety systems. However, challenges such as interfacial oxygen escape and unstable anode morphology continue to hinder their widespread applications. To address these issues, we have developed a fluoropolyether-based solid polymer electrolyte featuring a novel anion-rich solvation structure, which stabilizes the interface and enhances cycling stability. The resulting pouch cell demonstrates an ultra-high energy density (604 Wh/kg, 1027 Wh/L) and excellent safety under a nail penetration at a full charge condition, advancing solid-state battery technology and paving the way for safer, higher-energy systems.
