Carbon nanotubes have properties such as high electrical conductivity and strength, which make them suitable as supplemental materials for energy conversion and storage devices. Their use may improve the performance of lithium-ion batteries and supercapacitors, leading to more efficient energy solutions.
By Ibtisam AbbasiReviewed by Lexie CornerUpdated on Oct 17 2024 Carbon nanotubes have a diameter range of 0.7 to 50 nanometers and often comprise a single sheet of pure graphite that forms their cylindrical structure.They exhibit extraordinary properties, including exceptional strength, thermal conductivity, and electrical conductivity.
LIBs consist of three basic components: two electrodes—the anode and the cathode —and an electrolyte that allows charged ions to flow between the electrodes, enabling charging and discharging. While LIBs offer several advantages over other energy storage chemistries, they are also relatively fragile and require a protection circuit to ensure safe operation.
Through MOLECULAR REBAR® products, carbon nanotubes are untangled into discrete individual tubes of uniform size, allowing for their successful incorporation into lead-acid and lithium-ion batteries. This results in significantly stronger and more conductive energy storage products.
A comparison of pure CNTs and Fe-doped CNTs revealed that the latter exhibited superior performance, showing a 17 % increase in efficiency at 10 MPa pressure conditions. These findings demonstrate that Fe-CNTs are more effective than pristine CNTs for hydrogen storage applications due to their enhanced adsorption capacity.5
Beyond traditional supercapacitors, CNTs are now integral to the development of wearable supercapacitors due to their unique one-dimensional structure, high electrical and thermal conductivity, exceptional flexibility, strong mechanical strength, and low gravimetric density. These properties make CNTs ideal for applications in emerging markets, such as smart textiles and other wearable electronics.
