Carbon nanotubes, both single-wall and multi-wall, are widely used and well-characterized as nanofillers. These materials, composed of rolled graphene sheets, have unique properties due to their sp2 compounds. The tensile strength of carbon nanotubes is 100 times higher than that of steel, and the specific gravity is about 6 times lower.
CNTs come into question as promising nanofillers in composite materials, which are increasingly used in many technical solutions owing to. Its advantages over traditional structural materials such as metals, which offer high stiffness and good strength-to-weight ratio, are among the most attractive properties of CNT.
The new electrode design significantly increases the performance of existing lithium batteries - without having to invent new ones. If carbon nanotubes (CNT) are fixed vertically and firmly in the electrode, this leads to a tenfold increase in the performance of lithium batteries and a fivefold increase in their service life. If the electrodes in modern batteries are a rigidly structured vertical array of carbon nanotubes coated with an active substance, this results in a three-fold increase in energy density, a ten-fold increase in output and a five-fold increase in battery life.
