Three‐Dimensional Printed Microarchitected Hierarchically Porous Biodegradable PLA/S/CNT Nanocomposite Electrodes for High‐Performance Lithium–Sulfur Batteries

Advanced Materials Technologies, EarlyView.
Hierarchically microarchitected PLA/S/CNT cathodes are fabricated via scalable fused filament 3D printing as high‐sulfur‐loading hosts for rechargeable lithium–sulfur batteries. The assembled Li–S cells with sulfur loadings up to 17 mg cm−2 deliver an areal capacity of 9.2 mAh cm−2 and retain 96% of their discharge capacity after 100 charge–discharge ...
