Carbon nanotubes (CNTs)
Our electrode materials based on CNTs allow achieving capacities significantly more
compared to that of current commercial solutions.
CNTs have great potential for
electrochemical applications due to their high specific surface area, high
conductivity, excellent mechanical characteristics, high polarizability and the
possibility of chemical functionalization to provide better interaction with
electrolyte ions.
Using hybrid nanomaterials based on CNTs with metal sulfides will significantly enhance power charge/discharge processes, increase their capacity and efficient operating time without harming the environment. Our labarotory test shown that arrays of aligned CNTs can have a high electrochemical capacity and high electrical coupling (compared to conventional carbon materials such as activated carbon) and, therefore, high discharge capacity while being used as electrochemical electrodes.
Currently used activated carbon has a high surface area but low electrical coupling and, hence, low discharge capacity and lower ability of lithium intercalation. Compounds based on expensive metals and oxides are harmful to the environment, characterized by lower conductivity than carbon materials. Sulfides combination with carbon nanomaterials, especially carbon nanotubes, significantly improve the characteristics.
Hybrid supercapacitors based on arrays of carbon nanotubes and conducting polymers provide both high energy storage and power efficiency and, thus, filling up the currently existing gap between batteries and capacitors.
Our technology will significantly enhance power charge/discharge processes, increase their capacity and efficient operating time without harming the environment.
