Abstract
AbstractThe separator is an essential component of lithium‐ion batteries as it affects ion transport and safety performance. Herein, a novel class of separators fabricated from poly(vinyl alcohol) and heterometallic metal‐organic frameworks, which affords a higher density of open bimetal sites, stronger complexation with anions, more porous structure, and enhanced thermal stability and electrolyte wettability is reported. The adoption of such separators substantially increases lithium‐ion conductivity and lithium‐ion transference number, leading to batteries with prolonged lifespan, improved low‐temperature performance, and enhanced rate performance.
