Anion‐Sorbent Composite Separators for High‐Rate Lithium‐Ion Batteries

Novel composite separators containing metal–organic‐framework (MOF) particles and poly(vinyl alcohol) are fabricated by the electrospinning process. The MOF particles containing opened metal sites can spontaneously adsorb anions while allowing effective transport of lithium ions in the electrolyte, leading to dramatically improved lithium‐ion transference number t Li + (up to 0.79) and lithium‐ion conductivity. Meanwhile, the incorporation of...
