Abstract:
We introduce an eco-friendly sugar battery powered by renewable glucose and a reversible coordination complex, achieving performance that replaces noble metals on the cathode and circumvents sluggish oxygen reduction reactions. Utilizing biomass-derived fuel and carbon electrode, the battery delivers an impressive peak power density of ∼41 mW cm-2; nearly 7 times higher than conventional noble metal-based glucose-oxygen system, highlighting a prominent step toward sustainable energy technologies. The battery's non-toxic, refillable design, combined with the use of affordable materials, highlights its potential for both portable and large-scale energy applications.

Spontaneous redox reactions occur abundantly in nature. The chemical reaction occurring in a disposable AA battery powering our remote controls is one such example of a spontaneous redox reaction. Another example is the immersion of coiled copper wire into an aqueous silver nitrate solution. The reaction shows a gradual, visually impressive color change from colorless to bright blue and the formation of a grey precipitate on the copper wire. In this experiment,...
