Terminally Fluorinated Polyimide Interphase for Durable Lithium-Rich Layered Oxide Cathodes.

Lithium-rich layered oxides (LLOs) deliver high energy density via coupled cationic/anionic redox, but high-voltage oxygen activation generates radical-rich interfaces that accelerate electrolyte decomposition, surface reconstruction, and mechanical failure. Although polyimide serves as an oxidation-resistant interphas...
