Uniform fibrous-structured hollow mesoporous carbon spheres for high-performance supercapacitor electrodes

Nitrogen-Doped Hollow Mesoporous Carbon Spheres for Efficient Water Desalination by Capacitive Deionization

“…Particularly, the hollow cavity offers a high specific surface area along with reduced mass and charge diffusion lengths and the mesopores on the shell facilitate the ion diffusion kinetics by shorting the diffusion distance. These remarkable properties endow HMCSs as a promising candidate for EDLCs with the outstanding high-rate capacitive performances. − Inspired by this, the HMCSs have been extended to the CDI fields. In some pioneering works, the HMCSs as the CDI electrode materials were prepared by the modified Stöber method with a SiO 2 sphere as a hard template. , However, the improvement of desalination performance for the obtained HMCSs is still needed due to the high inner resistance and poor wettability of amorphous carbon materials.…”
