Researchers at Concordia University discovered that indigo, the natural dye used in denim, can enhance solid-state battery performance by supporting dual reactions within the cell. This synergy improves energy storage, stability, and operation even at low temperatures. By carefully managing interactions between indigo and the solid electrolyte, the team achieved high capacity and reliable cycling. The findings suggest that common, eco-friendly molecules could play a key role in next-generation sustainable batteries.
