A facile in-situ polymerization strategy towards polyimide/carbon black composites as high performance lithium ion battery cathodes

An in-situ polymerization strategy is utilized to fabricate the composites of polyimide and carbon black (PI/CBs) by the condensation of 1,2,4,5-benzenetetracarboxylic anhydride and p-phenylenediamine with the presence of carbon black. As the cathode material in LIBs, the PI/CB composite manifests an extraordinary capacity of 182 mAh g−1 at 0.1 A g−1, which can be retained as 116 m Ah g−1 even at 10 A g−1.178
