Researchers at Saint Louis University (St. Louis, MO) have developed a biodegradable fuel cell battery that runs on virtually any sugar source, from soft drinks to tree sap, and has the potential to operate three to four times longer on a single charge than conventional lithium ion batteries. If the battery continues to show promise during further testing and refinement, it could be ready for commercialization in three to five years.
â€œThis study shows that renewable fuels can be directly employed in batteries at room temperature to lead to more energy-efficient battery technology than metal-based approaches,â€ said study leader Shelley Minteer, PhD, an electrochemist at St. Louis University. â€œIt demonstrates that by bridging biology and chemistry, we can build a better battery that's also cleaner for the environment.â€
