开发了简便且可持续的路线，将生物质转化为与高导电石墨烯配合的分级多孔碳基质。通过调整碳基体的孔隙率以促进快速传质，并配合高导电性互连石墨烯框架以加速电子传输，碳硫阴极同时实现高面积和重量硫负载/含量（6 mg cm(-2)/67 wt%），并提供出色的电化学性能。在0.2 C电流密度下进行100次循环充放电测试后，可逆容量保持在707 mA h g(-1) 。 (C) 2017 Elsevier B.V. 保留所有权利。
Facile and sustainable route is developed to convert biomass into hierarchically porous carbon matrix cooperating with highly conductive graphene. By tailoring the porosity of the carbon matrix to promote fast mass transfer and cooperating highly conductive interconnected graphene frameworks to accelerate the electron transport, the carbon sulfur cathodes simultaneously achieve high areal and gravimetric sulfur loading/content (6 mg cm(-2)/67 wt%) and deliver outstanding electrochemical performance. After 100 cyclic discharge-charge test at the current density of 0.2 C, the reversible capacity maintains at 707 mA h g(-1) . (C) 2017 Elsevier B.V. All rights reserved.
