Electrochemical Activity of Electrode Material Consisting of Porous Copper and Silica Aerogel

Electrochemically obtained copper was combined with silica aerogel (SiO2ag). Obtained composite (SiO2@Cu/CuxOy) was tested as an electrode in contact with LiPF6 in EC/DMC electrolyte. The electrochemical measurements showed the presence of complex redox couple activities of SiO2@Cu/CuxOy. This experiment was employed to help in understanding the carbon role used as an electric contact for silica in Li-Ion batteries and clarify the electrochemical process of lithium insertion into material. Studies allowed to explain the function of each component in electrode reaction of SiO2@Cu/CuxOy in contact with aprotic solvent.
