Yeast Bio-battery
Abstract
Utilizing microorganisms for bio-batteries is challenging, needing optimized microbial pathways and engineered electrochemical materials. Saccharomyces cerevisiae on recyclable PET electrodes forms the first yeast-based green battery with iota-carrageenan hydrogel and potassium ferricyanide, achieving 450 mV and high cyclability, supporting environmentally friendly bio-batteries.
