Homemade Laserscribe Graphene Supercapacitor Test

Here I am comparing the three different graphene supercapacitors that Ive made. After charging them with a DC current at 4.2 volts, I tested there output voltage. Here are the 3 different caps:\r
\r
-One is made with 1g polyvinyl alcohol, 10g distilled water, and .8g of 85% phosphoric acid. \r
-One is made from 5g elmers glue (polyvinyl acetate and water), and 1g of 85% phosphoric acid.\r
-One is made with a tissue paper seperator that has been soaked in a solution of 25% phosphoric acid and 75% distilled water. The assembly was enclosed with Kapton tape.\r
\r
All the leads were painted with a conductive paint to ensure a good connection. Over all the tissue paper cell performed the best in a voltage test achieving a consistent voltage output of ~1.2V. The two solid state capacitors performed almost identically (before one of the leads got messed up) achieving consistent voltage outputs of ~.7V.\r
