| Description |
A new class of polymer gel electrolyte (PGE) was
synthesized using acrylamide as host polymer and LiClO4 as
dopant. The polymer gel was subjected to electrochemical
AC impedance analysis and thermal analysis. The polymer
has conductivity in the order of 10−3 S cm−1 at ambient
temperature. Thermogravimetric analysis (TGA) revealed the
effect of dopant on host polymer matrix. A supercapacitor
was fabricated using acrylamide based polymer gel electrolyte
with activated carbon as electrode material and it was
subjected to various electrochemical techniques like cyclic
voltammetry, electrochemical AC impedance analysis and
galvanostatic charge–discharge tests at various current
densities. From cyclic voltammetry a specific capacitance
of 28 F/g was obtained at a scan rate of 10 mV/s. The
capacitor had good self-discharge behavior and good cycle
life of more than 10,000 cycles. The coulombic efficiency
was more than 95%. These results indicate that this
acrylamide-based polymer gel electrolyte doped with LiClO4
is a potential electrolyte for electric double-layer capacitors
(EDLCs).
