Sodium‐Ion Batteries: Superior Sodium Storage in 3D Interconnected Nitrogen and Oxygen Dual‐Doped Carbon Network (Small 19/2016)

On page 2559, Y. Yu and co-workers fabricate a N,O-dual doped carbon (denoted as NOC) network by chemical activation of the bacterial cellulose derived carbon with KOH. The NOC possesses 3D well-defined porosity and the N, O-dual doping induces active sites, contributing to the enhanced sodium storage. When used as anode for sodium-ion battery, it delivers excellent electrochemical performance.
