Abstract:

Bacterial cellulose (BC) is a biopolymer with various outstanding properties, such as pure composition, nanosized fibers, and high water retention. Based on these properties, BC was employed in this thesis as a scaffold to process electrodes for electrochemical energy storage and conversion (EESC) applications. In general, the nanofibers allow high specific area and open porosity for optimal transport, but their insulating character prevents direct use. To obtain suitable conductivity, carbonization and metal coating were studied, respectively. Then, their electrochemical performance in EESC applications was investigated.
