An acid-pasting approach is developed in this work to fabricate the composite of perylenetetracarboxylic diimide (PTCDI) and carbon black in concentrated sulfuric acid. Different from traditional mechanical mixing, the solution-based fabrication strategy enables the sufficient blending of PTCDI as active component and carbon black as conductive agent in the PTCDI/CB composite. Serving as the cathode material, the PTCDI/CB composite shows excellent electrochemical performances in both lithium ion battery (137 mAh g⁻¹ at 100 mA g⁻¹ and 110 mAh g⁻¹ at 2000 mA g⁻¹) and sodium ion battery (134 mAh g⁻¹ at 100 mA g⁻¹ and 99 mAh g⁻¹ at 1000 mA g⁻¹), which are comparable to the state-of-art organic/inorganic cathode materials. Considering the simplicity of the processing procedures and the low cost of the starting materials, the acid-pasting approach is a highly attractive method for the solution-based manufacturing of organic secondary battery electrodes.

在这项工作中开发了一种酸浸法，以在浓硫酸中制备per四羧酸二酰亚胺（PTCDI）和炭黑的复合材料。与传统的机械混合不同，基于解决方案的制造策略可在PTCDI / CB复合材料中充分混合PTCDI作为活性成分和炭黑作为导电剂。作为阴极材料，在这两个锂离子电池（137毫安克PTCDI / CB复合显示出优异的电化学性能^-1在100mA克^-1和110毫安克^-1在2000毫安克^-1）和钠离子电池（ 134毫安克^-1在100mA克^-1和99毫安克^-1以1000mA克^-1），可与最先进的有机/无机阴极材料相媲美。考虑到处理过程的简单性和起始材料的低成本，酸浸法是用于基于溶液的有机二次电池电极的制造中非常有吸引力的方法。
