Electrochemical properties of poly(anthraquinonyl imide)s as high-capacity organic cathode materials for Li-ion batteries

摘要: Abstract Redox-active organic materials are potential cathode for material-sustainable and environment-friendly Li-ion batteries. As is one of the most prominent features compounds, isomerism has a significant influence on their properties. Herein, we synthesize two isomeric pairs poly(anthraquinonyl imide)s (PAQIs) by simple one-pot reaction, investigate electrochemical properties as battery cathodes cyclic voltammogram galvanostatic discharge/charge cycling. The PAQI exhibit high reversible capacity 202 mAh g−1 stable cyclability with 80% retention over 200 cycles, remarkable rate performance, suggesting feasibility these high-capacity potentials PAQIs slightly lower than monomers. A further comparison four indicates plays role in performance electrode materials.
