Sustainable "sweet and salty" synthesis of hierarchical porous carbon for lithium-sulfur batteries

, 2022
State-of-the-art Li-S batteries (LSBs) still suffer from a series of technical issues, including rapid capacity fading, due to polysulfide dissolution and shuttling, low active material loading in the cathode, and sluggish reaction kinetics.

Mechanochemistry-assisted synthesis of hierarchical porous carbons applied as supercapacitors [PDF]

Beilstein Journal of Organic Chemistry, 2017
A solvent-free synthesis of hierarchical porous carbons is conducted by a facile and fast mechanochemical reaction in a ball mill. By means of a mechanochemical ball-milling approach, we obtained titanium(IV) citrate-based polymers, which have been processed via high temperature chlorine treatment to hierarchical porous carbons with a high specific ...
