Abstract- A supercapacitor stores energy electrostatically by polarizing an electrolytic solution. Though it is an electrochemical device there are no chemical reactions involved in its energy storage mechanism. This mechanism is highly reversible, allowing the supercapacitor to be charged and discharged hundreds of thousands to even millions of times. Recent advances in this field have been in developing solid state supercapacitors. In this paper, a low temperature synthesis of PZT by sol-gel route is achieved which is made into a homogeneous solution using Diethylene Glycol. The resulting solution is used as a liquid dielectric in a supercapacitor fabricated using common available plastic containers of different form factors and their electrical properties were measured. The average time taken to charge and discharge the supercapacitor was noted. It was also tested for lowered temperature conditions. The future prospects and applications of this technology are also discussed in this paper
