Realizing All‐Climate Li‐S Batteries by Using a Porous Sub‐Nano Aromatic Framework

Angewandte Chemie International Edition, Journal Year: 2022, Volume and Issue: 61(47)

Published: Oct. 4, 2022

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 ).

Sulfide-Based All-Solid-State Lithium–Sulfur Batteries: Challenges and Perspectives

Nano-Micro Letters, Journal Year: 2023, Volume and Issue: 15(1)

Published: March 28, 2023

Lithium-sulfur batteries with liquid electrolytes have been obstructed by severe shuttle effects and intrinsic safety concerns. Introducing inorganic solid-state into lithium-sulfur systems is believed as an effective approach to eliminate these issues without sacrificing the high-energy density, which determines sulfide-based all-solid-state batteries. However, lack of design principles for high-performance composite sulfur cathodes limits their further application. The cathode regulation should take several factors including insulation sulfur, well-designed conductive networks, integrated sulfur-electrolyte interfaces, porous structure volume expansion, correlation between account. Here, we summarize challenges regulating respect ionic/electronic diffusions put forward corresponding solutions obtaining stable positive electrodes.
