A new route for the preparation of mesoporous carbon materials with high performance in lithium-sulphur battery cathodes

摘要

A novel method for the preparation of highly mesoporous carbon materials (Kroll-Carbons; KCs) is described based on reactive carbo-chlorination etching of titania nanoparticles inside a dense carbon matrix leading to mesoporous carbons with precisely controllable porosity and high performance as cathode materials for lithium-sulphur (Li-S) batteries.
