Abstract
Outside front cover image: The safety issues of lithium-ion batteries have received attention because they use flammable organic electrolytes and the separator with poor thermal stability. Herein, we design a green, cellulose-based separator in a unique encapsulation structure, in which functional flame retardants are wrapped in microscrolls formed by the self-rolling of cellulose nanosheets upon freeze-drying. The obtained separator shows excellent flame retardancy, and it was quickly extinguished after burning for only 0.67 s in combustion experiment through a radical scavenging mechanism.
