%X 通过直接碳化制备了具有介孔结构的N、O杂原子掺杂活性污泥生物质碳,后续通过酸洗改性将其应用于非水系锂氧电池正极。其应用于正极可在200 mA/g的电流密度下提供7888 mAh/g的比容量。锂氧电池放电过程会产生例如Li2O2等导电性较差的物质,本文所制备的材料由于介孔丰富,可以促进氧、离子的传输,同时由于N、O杂原子掺杂促进了电化学活性因此可以获得较长的循环寿命。
N, O heteroatom-doped activated sludge biochar with mesoporous structure was prepared by direct carbonization, and then applied to the positive electrode of non-aqueous lithium-oxygen battery by pickling modification. Its application in the cathode can provide a specific capacity of 7888 mAh/g at a current density of 200 mA/g. The discharge process of lithium-oxygen batteries will produce substances with poor conductivity such as Li2O2. The materials prepared in this paper can promote the transport of oxygen and ions due to the abundant mesopores. At the same time, due to the doping of N and O heteroatoms, electrochemical activity can be promoted, and a longer cycle life can be obtained.
