The Electro-Physical Properties of Sulfonated Polyaniline and V_(2)O_(5) Composites

摘要

Sulfonated polyaniline-V_(2)O_(5) (SPANI-V_(2)O_(5)) composites synthesis has been carried out by the direct interaction of sulfonated polyaniline solution with aqueous sol of V_(2)O_(5). The conductivity (sigma) of the obtained sample is 1,25(centre dot)10~(-3) S/cm in comparison with usual V_(2)O_(5) (10~(-5)-10~(-4)S/cm). It prevents distruction of composite structure under penetration/removal Lii ions during charge-discharge process. That is why such material have wide implementation as cathode materials in Li chemical current sources.
