Waste Cochlospermum Gossypium tree bark gum prevents supercapacitors from degrading over 10's of 1,000's of charging cycles

"better-performing, more eco-friendly... acidic electrolytes cause unwanted side reactions with their metal electrodes, reducing ability to hold full charge over time... polysaccharide kondagogu gum plus sodium alginate becomes spongelike biopolymer KS... added to acidic electrolyte creates protective layer over carbon electrodes, still allowing ion transport... 93% (instead of 58%) of full energy capacity after 30,000 cycles... waste gum is otherwise a headache for the Indian government to dispose of"
