Study for Synthesis and Ionic Conductivity of Polyionomer Lithium Tetrafluoroborate Film for Secondary Lithium Battery Polymeric Electrolytes

Novel polyionomer lithium tetrafluoroborates including poly(1-[(4-ethenylphenyl)methyl]-3-buthyl imidazolium lithium tetrafluoroborate) (poly(EMBI/Li+)) and lithium tetrabonate poly(3-octyl-1-vinyl imidazolium lithium tetrafluoroborate) (poly(OVI/Li+)) films were synthesized for use as polymeric electrolytes in secondary lithium battery cells. The successfully synthesized of vinyl monomer with ionic properties and polyioners were confirmed via 1H-NMR, FT-IR, GC-Mass, Scanning Electron Microscopy (SEM), and impedance analysis, respectively. From impedance analysis, the ion conductivity of the poly(OVI/Li+) and poly(EMBI/Li+) films is shown as 2.69x10(-4) S/cm and 5.00x10(-7) S/cm respectively. The prepared poly(OVI/Li+) film is suitable for use as secondary lithium battery polymeric electrolyte.
