SINTESIS MEMBRAN POLIMER ELEKTROLIT DARI BAHAN POLI(VINIL ALKOHOL) DENGAN LITIUM HIDROKSIDA(LiOH) SEBAGAI SUMBER ELEKTROLITNYA
Abstrak: Electrolyte polymer
membranes were synthesized by solution cast method. Fabrication of polymer
electrolyte memb ranes done by using the polymer poly (vinyl alcohol)(PVA) and
Lithiu m Hydro xide (LiOH) as the source of the electrolyte. PVA dissolved in
distilled water while heated at 50 0 C for 2 hours. For preparing LiOH
solution, the same procedure as for PVA solution were heated for an hour.
Futhermore, PVA solution and LiOH solution were mixed wh ile stirred and heated
at 50 0 C for one hour. Then, the mixture solution was evaporated for 2 days
which ultimately resulted in a thin sheet-transparent membrane. The perfo
rmance of poly mer electro lyte membrane PVA -LiOH characterized by physical
properties and conductivity analysis using Electrochemical Impedance
Spectroscopy (EIS). The maximum measurement results and conductivity values
obtained in 9% concentration of LiOH, reach 2.48 x10 -4 S.cm -1 .
