An acid-pasting strategy towards PTCDA based high performance lithium/sodium ion battery cathodes

An acid-pasting approach is developed to prepare the composites of 3,4,9,10-perylenetetracarboxylic dianhydride and carbon black (CB/PTCDA). The solution-based fabrication strategy can greatly improve the electrochemical performances of the CB/PTCDA composites in both lithium ion battery and sodium ion battery.420
