Phys.org June 3, 2021 A team of researchers in Switzerland developed and implemented the concept of a biodegradable electricity storage device. They developed gelatinous inks which consists of cellulose nanofibers and cellulose nanocrystallites, carbon in the form of carbon black, graphite and activated carbon. They used glycerin, water and two different types of alcohol to mix the ingredients and a pinch of table salt for ionic conductivity. They built a functioning supercapacitor from four layers of these ingredients flowing from a 3D printer one after the other: a flexible substrate, a conductive layer, the electrode and finally the electrolyte. The […]

‘Papertronics’ could fold, biodegrade and be the basis for the next generation of devices
Nanowerk September 21, 2018 Researchers at the State University of New York‐Binghamton have developed a bacteria‐powered battery by building microbial fuel cells with inactive, lyophilized exoelectrogenic cells which generates power within minutes of adding saliva. An oxygen‐tight interface and engineered conductive paper reservoir boosts microbial electron transfer efficiency. Exoelectrogenic bacteria preinoculated in the paper battery is freeze‐dried for long‐term storage and can be readily rehydrated for on‐demand power generation. Sixteen microbial fuel cells are incorporated on a single sheet of paper while all are connected in series with two electrical switches mounted on a paper circuit board, produced more than […]
