| 1 | Microfibrillated Cellulose Based Ink for Eco-Sustainable Screen Printed Flexible Electrodes in Lithium Ion Batteries显示文摘Free organic solvent ink containing graphite,carboxymethyl cellulose and microfibrillated cellulose as active material,dispersing and binder,respectively,has been formulated to produce flexible and ecosustainable electrodes for lithium ion batteries.Content ratio of components and dispersion protocol were tailored in order to have rheological properties suitable for a large and cheap manufacturing process as well as screen printing.The bio-sourced printed electrodes exhibit a high porosity value of 70% that limits the electrochemical performances.However,the calendering process enhances electrode performances by increasing the reversible capacity from 85 until 315 m Ah/g and reducing porosity to an optimal value of 34%.Moreover the introduction of 2%w/w of monofluoro-ethylene carbonate in the electrolyte reduced their reversible capacity loss of 11%in the printed electrode. | Oussama El Baradai Davide Beneventi Fannie Alloin Roberta Bongiovanni Nadege Bruas-Reverdy Yann Bultel Didier Chaussy | 2016 | Journal of Materials Science & Technology2016，32，6： | 3 |
