Freezing‐Assisted Direct Ink Writing of Customized Polyimide Aerogels with Controllable Micro‐ and Macro‐ Structures for Thermal Insulation

Tiantian Xue, Shijia Yuan, Yi Yang, Xiong Wan et autres

Abstract Polyimide (PI) aerogels have attracted attention in thermal management due to their low thermal conductivity, high porosity, and robust mechanical properties. However, building PI aerogels with elaborately tailored micro‐ and macro‐ structures for optimized thermal insulation performance in specific scenarios remains …

Ultrathin MnO2 Sheet Arrays Grown on Hollow Carbon Fibers as Effective Polysulfide-Blocking Interlayers for High-Performance Li–S Batteries

Guojie Chao, Longsheng Zhang, Shijia Yuan, Tiantian Xue et autres

Lithium–sulfur (Li–S) batteries are clean energy conversion devices with high theoretical energy densities and specific capacities. However, Li–S batteries exhibit poor cycling stability during the practical test, mainly because of the detrimental shuttle effect of intermediate lithium polysulfides (LiPSs). Here, we report …
