Abstract
Front Cover: Developing super stability and long-span life of sodium ion batteries (SIBs) can significantly widen their practical applications. However, the low specific Na+ storage performance and poor cycle stability at large current density are still unsatisfactory. In article number BTE.20220046, Sun et al. reported a pine-derived carbon/SnS2@reduced graphene oxide film with fast ion/electron transport micro-channel, which was used as a SIB anode and cycled 800 times at 5 A g−1. This work provides a novel design strategy for the application of biomass-derived carbon in energy storage.
