Abstract

Abstract : Hierarchical N/S‐codoped carbon microspheres with expanded interlayer distance and enhanced conductivity are fabricated facilely from cellulose/polyaniline composite in a "green" and low‐cost route. This material achieves a high reversible capacity of ≈280 mA h g −1 at 30 mA g −1 and superior rate performance of ≈130 mA h g −1 at 10 A g −1, and ultralong cycle life of more than 3000 cycles as an anode material for sodium‐ion batteries, holding great promise for economic large‐scale energy storage.
