Low-cost Supercapacitors for Household Electrical Energy Storage and Harvesting

Supercapacitors have the ability to deliver an order of magnitude more power than batteries. However, at the present, they are more expensive than batteries and not widely available. Supercapacitors have the capability to be more energy efficient and powerful than batteries and in some cases they will complement or displace batteries. The goal of this project was to develop a method of simple assembly of efficient yet cheap supercapacitors, which could be assembled outside a laboratory by anyone. These supercapacitors could be used as demonstrations or models of simple devices for capacitive energy storage, but in the future could be used in homes or in developing countries and remote locations.
