Materials: Kitchen sponge used as platform for energy device
They added that compared to aqueous electrolytes, the energy density of supercapacitors in 1M Et4NBF4 tripled and the value was improved six-fold when using 1M LiClO4 as the electrolyte. They also said that the cycling performance in organic electrolytes was inferior to aqueous electrolytes, but the devices in organic electrolytes retained a significant energy density advantage even after 10,000 cycles.
