Description:
Renewable and cheap materials in electrodes could meet the need for low-cost, intermittent electrical energy storage in a renewable energy system if sufficient charge density is obtained. Brown liquor, the waste product from paper processing, contains lignin derivatives. Polymer cathodes can be prepared by electrochemical oxidation of pyrrole to polypyrrole in solutions of lignin derivatives. The quinone group in lignin is used for electron and proton storage and exchange during redox cycling, thus combining charge storage in lignin and polypyrrole in an interpenetrating polypyrrole/lignin composite.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Milczarek, Grzegorz -- Inganas, Olle -- New York, N.Y. -- Science. 2012 Mar 23;335(6075):1468-71. doi: 10.1126/science.1215159.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Chemistry and Technical Electrochemistry, Poznan University of Technology, Poznan, Poland.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22442478" target="_blank"〉PubMed〈/a〉
