Fecha de publicación: | 22-ago-2018 | Editor: | John Wiley & Sons | Citación: | ChemSusChem 11(16): 2776-2787 (2018) | Resumen: | Graphitized carbon materials from biomass resources were successfully synthesized with an iron catalyst, and their electrochemical performance as anode materials for lithium-ion batteries (LIBs) was investigated. Peak pyrolysis temperatures between 850 and 2000 °C were covered to study the effect of crystallinity and microstructural parameters on the anodic behavior, with a focus on the first-cycle Coulombic efficiency, reversible specific capacity, and rate performance. In terms of capacity, results at the highest temperatures are comparable to those of commercially used synthetic graphite derived from a petroleum coke precursor at higher temperatures, and up to twice as much as that of uncatalyzed biomass-derived carbons. The opportunity to graphitize low-cost biomass resources at moderate temperatures through this one-step environmentally friendly process, and the positive effects on the specific capacity, make it interesting to develop more sustainable graphite-based anodes for LIBs. | Versión del editor: | https://doi.org/10.1002/cssc.201800831 | URI: | http://hdl.handle.net/10261/193254 | DOI: | 10.1002/cssc.201800831 | ISSN: | 1864-5631 | E-ISSN: | 1864-564X |
