Aqueous and organic inks of carbon xerogels as models for studying the role of porosity in lithium-ion battery electrodes

The electrochemical performances of lithium-ion batteries depend to a great extent on the method used to prepare the electrodes and on the pore texture of the active material. In the present study, carbon xerogels with different pore sizes and pore volumes were synthesized by means of microwave heat...
