Stabilising Cobalt Sulphide Nanocapsules with Nitrogen-Doped Carbon for High-Performance Sodium-Ion Storage

Cobalt sulphide nanoparticles are encapsulated in nitrogen-rich carbon cages via a simple and scalable method. Insight into sodium storage mechanism is systematically studied via in situ TEM and XRD techniques. The sodium-ion capacitor device achieved high energy densities of 101.4 and 45.8 Wh kg(−1...

Sumario:Cobalt sulphide nanoparticles are encapsulated in nitrogen-rich carbon cages via a simple and scalable method. Insight into sodium storage mechanism is systematically studied via in situ TEM and XRD techniques. The sodium-ion capacitor device achieved high energy densities of 101.4 and 45.8 Wh kg(−1) at power densities of 200 and 10,000 W kg(−1), respectively, holding promise for practical applications.
