| 英文摘要 | cyanoethylated carboxymethyl chitosan (cn-ccts) has been synthesized through a straightforward cyanoethylation reaction by reacting ccts with acrylonitrile in naoh aqueous solution. cn-ccts shows improved adhesion strength of 0.047 n/cm as compared with 0.013 n/cm for ccts after introducing cyanoethyl group in the chemical structure of ccts. the electrochemical performances of lifepo4 electrode with cn-ccts binder have been investigated and compared with those using water soluble sodium carboxymethyl cellulose (cmc) and non-aqueous polyvinylidene difluoride (pvdf) binder. lifepo4 electrode with cn-ccts exhibits better cycling stability and rate capability, retaining 56.3% capacity of c/5 at 5c rate as compared with 48.4% and 32.8% for cmc and pvdf, respectively. cyclic voltammetry and electrochemical impedance spectroscopy measurement reveal that lifepo4 electrode with cn-ccts has a more favorable electrochemical kinetics than that with cmc and pvdf, thus better rate capability.
