In-situ electropolymerized bipolar organic cathode for stable and high-rate lithium-ion batteries

To address the dissolution issue and enhance electrochemical performance of organic electrode materials, herein, a bipolar cathode was prepared by in-situ electropolymerization amino-phenyl carbazole naphthalene diimide (APCNDI). APCNDI is composed n-type 1,4,5,8-naphthalene tetracarboxylic that stores Li cations p-type groups which react with anions serve as polymerization sites. Electropolymerization completely eliminated problem APCNDI, electropolymerized demonstrated reaction excellent performance, stable cycling capacity retention 92 mA h g−1 after 1000 cycles, superior rate 72 at 10 A g−1. The feature reactions were systematically investigated verified multiple characterization techniques. Our findings provide novel strategy for design fabrication electrodes high-performance batteries.
