Abstract Lithium–sulfur (Li–S) batteries stand out for their high theoretical specific capacity and cost‐effectiveness. However, the practical implementation of Li–S is hindered by issues such as shuttle effect, tardy redox kinetics, dendrite growth. Herein, an appealingly designed covalent organic framework (COF) with bi‐functional active sites cyanide groups polysulfide chains (COF‐CN‐S) developed cooperative functional promoters to simultaneously address dendrites effect issues. Combining in situ techniques calculations, it can be demonstrated that unique chemical architecture COF‐CN‐S capable performing following functions: 1) The delivers significantly enhanced Li + transport capability due abundant ion‐hopping (cyano‐groups); 2) functions a selective ion sieve regulating dynamic behavior anions , thus inhibiting growth; 3) acting mediator, effectively control electrochemical polysulfides enhance conversion kinetics. Based on above advantages, endows excellent performance. This study highlights significance interface modification offers novel insights into rational design materials realm.

Lithium-sulfur (Li-S) batteries with high energy density are currently receiving enormous attention. However, their redox kinetics at low temperature is extremely tardy, and polysulfides shuttling serious temperature, which severely hinders the implementation of wide-temperature Li-S batteries. Herein, we propose an all-climate battery based on ether-based electrolyte by using a porous sub-nano aromatic framework (SAF) modified separator. It's demonstrated that fully conjugated SAF-3 small pore size (0.97 nm) narrow band gap (1.72 eV) could efficiently block elevated boost conversion temperature. Consequently, cells work well in wide ranging from -40 to 60 °C. Furthermore, when operated room cell exhibits 90 % capacity retention over 100 cycles under high-sulfur loading (5.0 mg cm-2 ) lean (5 μL mg-1 ).
