An effective strategy to tackle the twin crises of global deforestation and fossil fuel depletion is to recycle biomass materials for energy storage devices. This study reports a unique and innovative solution to capitalize on a currently overlooked resource to produce high‐performance lithium–sulfur (Li–S) batteries from recycled paper. The recycled paper fibers are creatively composited with graphene oxide sheets via a capillary adsorption method. The recycled paper/graphene oxide hybrid is then converted to activated paper carbon/reduced graphene oxide (APC/graphene) scaffold for sulfur infiltration. The assembled Li–APC/graphene/S battery exhibits a superior lifespan of 620 cycles with an excellent capacity retention rate of 60.5%. An APC interlayer is sandwiched between the Li anode and the separator to suppress the degradation of Li anode by preventing the nonhomogeneous growth of mossy Li whiskers, stretching the battery lifespan up to 1000 cycles with a capacitance retention rate of 52.3%. The capillary adsorption method coupled with the porous carbonaceous anode interlayer configuration creates a new opportunity for the development of batteries derived from porous biomass materials.

用于容量更大，寿命更长的锂硫电池的毛细化复合再生纸/石墨烯支架

解决全球森林砍伐和化石燃料枯竭的双重危机的有效策略是回收用于储能设备的生物质材料。这项研究报告了一种独特的创新解决方案，可以利用当前被忽视的资源来利用再生纸生产高性能锂硫（Li–S）电池。通过毛细吸附法将再生纸纤维与氧化石墨烯片创造性地进行复合。然后将回收的纸/氧化石墨烯杂化物转化为活性纸碳/还原的氧化石墨烯（APC /石墨烯）支架，以进行硫渗透。组装好的Li–APC /石墨烯/ S电池具有620次循环的超长使用寿命，出色的容量保持率达60.5％。APC中间层夹在Li阳极和隔板之间，通过防止生苔Li晶须的不均匀生长来抑制Li阳极的降解，从而将电池寿命延长至1000次循环，电容保持率为52.3％。毛细吸附法与多孔碳质阳极夹层结构相结合，为开发由多孔生物质材料衍生的电池创造了新的机会。
