University of Kentucky researchers pressure-cooked bourbon stillage into hydrochar; its supercapacitors stored up to 25 times more energy, while another design retained 96% capacity after 10,000 cycles

Chemists at the University of Kentucky have pioneered a remarkable technique to recycle bourbon stillage, converting this distillation waste into carbon-rich hydrochar for the creation of advanced supercapacitors. These innovative energy storage devices not only outperform traditional models in energy retention but also exhibit outstanding reliability, maintaining a high level of storage even after prolonged use.
