Recent Advances of Cellulose‐Based Materials and Their Promising Application in Sodium‐Ion Batteries and Capacitors. Issue 47 (9th September 2018) - Zhang, Tianyun
Abstract: Cellulose as the most abundant natural biopolymer on earth has shown promising potential because of its excellent physical, mechanical, and biocompatible properties, which are very important for sustainable energy storage systems (ESSs). In this review, a comprehensive summary of the applications involving all kinds and forms of cellulose in the advanced Na‐related ESSs, including sodium ion batteries (SIBs) and sodium ion capacitors (SICs), is presented. For cellulose, the impact of various structures and surface chemical properties on the electrochemical performance is focused on. In particular, the latest developments in cellulose‐based binders and separators are highlighted. In addition, an in‐depth understanding of the structure and performance of electrode materials and the storage mechanism of a hard carbon anode derived from cellulose for SIBs is provided. Further, the manufacturing of full‐cellulose‐based SICs assembled by all parts of devices including hard carbon anodes, active carbon cathodes, binders, and separator based on cellulose or cellulose derivatives is reviewed. Finally, the prospects of cellulose‐based energy storage systems on several issues that need further exploration are presented. Abstract : The systematic research on cellulose‐based Na‐related energy storage systems, including sodium ion batteries and sodium ion capacitors, is reviewed. In particular, the recent advances in cellulose‐based separators, binders, and dual carbon sodium ion capacitors are summarized. On the basis of this, potential research avenues in energy fields of cellulose‐based materials are suggested.
