Sodium‐Ion Batteries: Carbon Quantum Dots and Their Derivative 3D Porous Carbon Frameworks for Sodium‐Ion Batteries with Ultralong Cycle Life (Adv. Mater. 47/2015)

A new synthesis methodology for carbon quantum dots (CQDs) for large-scale production is proposed for the first time by X. Ji and co-workers on page 7861. The as-obtained CQDs can be transformed into 3D porous carbon frameworks exhibiting superb sodium storage properties with an ultralong cyclelife and ultrahigh rate capability, which are comparable to state-of-the-art carbon anode materials for sodium-ion batteries.
