Advanced Nanocellulose‐Based Composites for Flexible Functional Energy Storage Devices (Adv. Mater. 48/2021)

Nanocellulose-Based Composites In article number 2101368, Chuanling Si, Peiwen Liu, Kai Zhang, and co-workers comprehensively review flexible nanocellulose-based composites for advanced energystorage systems, such as batteries and supercapacitors. Nanocellulose, with sustainable natural abundance, superb properties, and unique structures, promotes the flexibility, versatility, and ion-transport dynamics of energy-storage materials. Nanocellulose-based composites give rise to energy-storage devices with outstanding electrochemical performance, flexibility, light weight, and eco-friendliness for the forthcoming smart-electronics era.
