In this study, the authors report the highly efficient, multigram-scale synthesis of an ester-functionalized, poly(aniline-co-fluorene) polymer. The excellent solubility and film-forming ability of this polymer facilitate its application as a reversible battery cathode. Electrochemical quartz crystal microbalance with dissipation monitoring confirms a multi-electron transfer process, resulting in a specific discharge capacity of 51 mAh g−1 and a high reversible doping level of 0.69. Galvanostatic cycling at 1 C demonstrates excellent electrode stability with a capacity retention of 95.2% after 100 cycles. Therefore, this work demonstrates a novel electroactive polymer that exemplifies how chemical functionality may be used to properly balance processability and electroactivity of macromolecular battery cathodes. A poly(aniline-co-fluorene) (PAF) polymer is synthesized on multigram scale as battery cathode material. Excellent solution processability of PAF allows binder-free fabrication of organic polymer cathodes that exhibit multi-electron transfer and high battery performance. This work has provided a novel molecular design principle for utilizing conjugated polymers in lithium ion battery applications.
