1Natural nori-based porous carbon composite for sustainable lithium-sulfur batteries显示文摘The practical applications of lithium-sulfur(Li-S)batteries are limited by the low conductivity of sulfur and the shuttle effect of soluble polysulfides during the charge-discharge process.At the same time,biomass-based carbon materials have been acknowledged as the cost-effective and direct settlement to mitigate or overcome these problems due to their renewability,facile processing,and pollution-free characteristics.Therefore,in this work,we report the natural nori-based CoO nanoparticles decorated hierarchical porous carbon(HPC)for high-capacity Li-S battery cathodes.The HPC with an extremely high surface area of 2089 m^(2)g^(−1)provides a good substrate for the accommodation of CoO nanoparticles,which can effectively seize the lithium polysulfides and facilitate their redox conversion.As a result,the CoO-HPC/S cathode exhibits a high discharge capacity of 1557.1 mA h g^(−1),as well as excellent rate performance and cycling stability.Due to the naturally abundant nori-based cathode materials,the resultant Li-S battery is supposed to be an attractive and sustainable energy storage device.LIU Hu LIU WeiLin MENG FanCheng JIN LiangYu LI ShuLin CHENG Sheng JIANG ShuDong ZHOU RuLong LIU JieHua 2022Science China(Technological Sciences)2022,65,10:0
