Description
Summary:The emerging generation of flexible energy storage devices has accelerated the research pace in terms of new materials, new processing techniques, and new designs that can meet the demands of mechanical stability upon bending or stretching at an acceptable cost, without compromising their electrochemical performance. Among the materials currently explored, biomass‐derived materials have received extensive attention, because they are renewable, low in cost, earth‐abundant and structurally diverse. This review is focused on fundamentals and applications of the bio‐derived material bacterial cellulose (BC) in flexible electrochemical energy storage systems. Specifically, recent advances are summarized in the utilization of BC in stretchable substrates, carbonaceous species, and scaffolds for flexible core component construction. Finally, several perspectives related to BC‐based materials for flexible electrochemical energy storages are proposed, aiming to provide possible future research directions in these fields. Bacter the future? Owing to its remarkable mechanical properties, three‐dimensional nanofibrous structure and high porosity, bacterial cellulose (BC) is regarded as a key material for future flexible electrochemical energy storage technologies. This Review summarizes recent progress related to BC, carbonized BC (CBC), and their composites in flexible energy storage systems and proposes potential future developments.
