Utilisation de procédés papetiers et de fibres cellulosiques pour l'élaboration de batteries Li-ion Elaboration of Li-ion batteries using cellulose fibers and papermaking techniques

Abstract : This work investigates the production of low cost, low environmental impact, easily up-scalable and recyclable cellulose-based Li-ion batteries. Two main research approaches were explored. At first, microfibrillated cellulose was used for the production of paper-like anodes by means of a water-based casting process.Then, a papermaking approach was adopted and the majority of the experimental work was focused on the use of cellulose fibers for the production of paper-electrodes (i.e. anodes and cathodes) and paper-separators by means of a water-based filtration process.The prepared electrodes are easy to handle and self-standing with good electrochemical characteristics, comparable with that of standard synthetic polymer-bonded electrodes.
