Polymer Nanocomposite Electrolytes

Lithium-ion conducting nanocomposite solid electrolytes were synthesized from polyethylene oxide (PEO), poly(methyl methacrylate) (PMMA), LiClO4, and Li1.3Al0.3Ti1.7(PO4)3 (LATP) ceramic particles. The synthesized nanocomposite electrolyte consisted of LATP particles and an amorphous polymer. LATP particles were homogeneously distributed in the polymer matrix. The nanocomposite electrolytes were flexible and self-standing. The lithium-ion conductivity of the nanocomposite electrolyte was almost an order of magnitude higher than that of the PEO/PMMA solid polymer electrolyte.

AbstractThe ionic conductivity of ammonium-based solid polymer films of poly(vinylidene fluoride) (PVDF) blended with MG49, a graft of natural rubber and poly(methyl methacrylate), with various compositions of ammonium triflate NH4CF3SO3, was investigated. As a result, 30 wt.% of NH4CF3SO3-doped polymer electrolyte exhibits the highest ionic conductivity at 6.32×10-4 S/cm at room temperature. The conductivity enhancement can be attributed to the increase in the number of NH4+ as charge carriers. The significance of the blend is the increase of one order in ionic conductivity as compared with pure PVDF electrolyte. The temperature dependence of conductivity of the electrolyte does not obey the Arrhenius law. However, the conductivity increases with temperature and it reached 1.56×10-3 S/cm at 363 K. X-ray diffraction reveals a decrease in crystallinity of the electrolyte upon the addition of NH4CF3SO3 salt. This result is supported by scanning electron microscopy. Linear sweep voltammetry demonstrates that the anodic stability of the electrolyte is up to 4 V. Therefore, the electrolyte shows good compatibility with high-voltage electrode. Hence, this electrolyte system can be a prospective candidate as lithium-ion conducting electrolyte for lithium batteries.
