摘要：

In this work, unique porous carbon sheets (PCSs) are developed via a facile synthesis. The obtained PCS delivers long-range conductive framework, abundant active interfaces, rich element doping, and notably a high inner porosity that builds up an admirable 3D network for multidirectional ion transfer. Such unique architecture and surface chemistry enable ultrafast sulfur electrochemistry as well as high-efficiency inhibition on polysulfide shuttling via the dually physical and chemical sulfur confinement. The PCS-based sulfur electrodes achieve superb rate capability up to 10 C, outstanding cyclability over 1000 cycles, and high areal capacity of 4.8 mA h cm(-2). This work offers an appealing model of material engineering for fast and reliable lithium-sulfur batteries, as well as guidance for rational structural design in extended energy storage and conversion systems.
