Researchers synthesize battery cathode from lignin derivatives

Green Car Congress

The polypyrrole is able to hold on to the loose proton until the charge is released and the proton returns to the quinone group of the lignin derivative. Renewable energy systems based on intermittent sources require methods for power balancing over time, and thus some means of storage. doi: 10.1126/science.1215159.
