researchers at the State University of New York at Binghamton have developed a carbon - based battery that is biodegradable in ethanol , according to a study in Advanced Sustainable Systems . The battery was made up of a paper sheet and engineered polymers , and the team said it demonstrated a surprising level of efficiency . The team said power levels on the low - cost , flexible batteries could be boosted by simply folding or stacking them .
Researchers at the State University of New York at Binghamton have developed a paper-based battery that is biodegradable in water, according to a paper in Advanced Sustainable Systems. The biobattery was made up of a paper hybrid and engineered polymers, and the team said it demonstrated a surprising level of efficiency. The team said power levels on the low-cost, flexible batteries could be boosted by simply folding or stacking them.
