Part of the Yale Center for Materials Innovation Speaker Series, Prof. Steve Eichhorn, University of Bristol, UK, will speak about the history of cellulosic materials used in both batteries and capacitors, introducing the use of nanocellulose, and carbon materials derived from this material for use as electrodes and also as the separators in batteries. Work carried out on supercapacitors will also be discussed, and how things are progressing with the use of biomass for capacitive deionisation devices. Finally, some very recent work on the combination of graphene and cellulose for the production of triboelectric nanogenerators will be introduced and discussed, showing how it might be possible to have an all-cellulose/polymer device, and potentially place such devices on clothing and other structures for the generation and storage of power.
