Abstract

Nanocomposite polymer electrolyte membranes were prepared by phase inversion technique in polyvinylidenefluoride-hexafluoropropylene (PVdF-HFP) matrix. These membranes were gelled with 0.5 M LiBOB in EC:DEC (1:1 v/v). These gel polymer membranes (GPMs) were incorporated with nanoparticles of AlO(OH)_n and prepared composite polymer membranes (CPMs) also. The a.c. impedance analysis shows that AlO(OH)_n filled membrane exhibits conductivity of 1.82 × 10^-3 S cm^-1 at ambient temperature. The Li/CPM/LiFePO₄ cell delivered a specific discharge capacity of 158 and 147 mAh g^-1 at first and at 20th cycle respectively discharged at C/20 rate. The cell experiences a capacity fade of 0.1 mAh g^-1 cycle^-1 over the investigated 20 cycles. The studies vindicate that AlO(OH)_n filled PVdF-HFP polymer membranes could be the potential material to use as separator cum electrolyte in lithium batteries in conjunction with LiFePO₄ as a counterpart.
