Fine metal screen for curretn collection. Activated carbon/ graphite mixture bound with polyurethane then pressed- after drying.
Various electrode preps. Midle one has coated cellulose acetate thin film brushed on the activated carbon/ graphite surface with very thin paper added.
Right: same type of electrode composition with a mesh polyurethane coated with thin film of cellulose acetate while some acetone solvent still not evaporated.
Unit for bench-scale testing. One electrode placed in dialysis membrane separator and unit in small polyethylene bag. Opne system with non-volatile DES/ ion liquids to be tested for 50 cycles . Non-volatile liquids. Studying farad values, power density and energy density.
Promising systems will be closed systems.
