Electrode Materials: A Hierarchical N/S‐Codoped Carbon Anode Fabricated Facilely from Cellulose/Polyaniline Microspheres for High‐Performance Sodium‐Ion Batteries (Adv. Energy Mater. 6/2016)

Abstract: In article number 1501929, Jia Xie, Lina Zhang, and co‐workers present the construction of a hierarchical N/S‐codoped carbon anode via a cost‐effective and “green” route by pyrolyzing the cellulose/polyaniline composite microspheres. The micro‐nanometer and atomic‐level structure, designed via fabrication of the cellulose porous microspheres and N/S heteroatoms co‐doping, ensures the carbon electrode an excellent rate capability and ultra‐long cycle life in sodium‐ion batteries, making it highly promising for … Show more

“…While CNC1000 and CNC1300 have similar charge capacities at 0.1 A g −1 , the poor performance of CNC1300 at higher rates could exacerbate the imbalance between the kinetics of anodes and cathodes (Figure S5k, Supporting Information). Compared with the previously reported carbonaceous materials, where high carbonization temperatures are used, CNC1000 can deliver a good electrochemical performance after carbonization at only 1000 °C (Figure c). Hence, CNC1000 is the best choice for anodes in the full cell configuration.…”

“…The b ‐values of R 1 and R 2 of VS 4 are much larger than that of other three VS 4 −HC composites, indicating a representative of capacitive behavior during the discharge process. Furthermore, the equation below is applied to calculate the contributions of the two behaviors of the four samples: [ 57,58 ] ipV=k1v+k2v1/2 ipV/v1/2=k1v1/2+k2…”

“…The specific capacity maintains 400 mAh g −1 , with a nearly 100% Coulombic efficiency. This outperforms other carbon‐based anodes reported so far for SIBs in the literature (Figure d) . Table S1 in the Supporting Information compares the cycle life and stability of the N‐CNS electrode with other carbon‐based electrodes from the literature .…”

“…The pyridinic‐ and pyrrolic‐N‐doping have Na (K) ion adsorption energy of −4.76 eV (−4.36 eV) and −4.25 eV (−3.91 eV), respectively, while the graphite N‐doped structure has a lower adsorption energy of −0.37 eV (−0.88 eV) for Na (K). It is reasonable to assume that the N‐CNS with the highest content of pyridinic and pyrrole N correspond to the highest affinity to Na (K) ions . As seem from Figure b, the Na (K) adsorption changes significantly the density of states (DOS) of all electrodes.…”
