Abstract
In this paper, five hybrid copolymers of HCF/PANI,HCF/P(ANI:pPD=5:1),HCF/P(ANI:pPD=3:1),HCF/P(ANI:pPD=1:1),HCF/PpPD were prepared by in-situ synthesis using the prepared ferricyanic acid (HCF) as doping acid with electrochemical activity. The prepared hybrid material was further applied as cathode electrode to prepare lithium battery. And the structure, morphology, electrochemistry and battery performance of the prepared material were studied in detail. FTIR spectra show that hybrid materials have been successfully prepared. SEM results showed that with the increase of p-phenylenediamine monomer in aromatic amine copolymer, the morphology of hybrid materials gradually decreased from the granular morphology of HCF/PANI to a relatively flat stacking state. Cyclic voltammetric (CV) test showed that the redox reaction for arylamine polymer and HCF presented two obvious characteristic peaks. And the introduction of a small amount of p-phenylenediamine monomer caused the oxidation/reduction potential of hybrid material (HCF/P(ANI:pPD=5:1)) to be significantly close each other and the peak space to decrease. With further increasing the proportion of p-phenylenediamine monomer in aromatic amine copolymer, the oxidation peak and reduction peak of hybrid material move reversely to high potential and low potential respectively. Battery performance studies showed that the initial charge-discharge specific capacities of HCF/PANI,HCF/P(ANI:pPD=5:1),HCF/P(ANI:pPD=3:1),HCF/P(ANI:pPD=1:1),HCF/PpPD were 191.3 and 103.5 mAh·g-1, 105.8 and 82.8 mAh·g-1, 86.9 and 73.9 mAh·g-1, 55.4 and 28.1 mAh·g-1, 19.2 and 12.6 mAh·g-1, respectively With the increase of p-phenylenediamine comonomers in hybrid materials, the cyclic stability of electrode materials has been improved to some extent. At the same time, the hybrid material has good rate retention.
