The high discharge capacity (ca. 380 mAh g⁻¹ in the first cycle) and diffusion coefficients of Li⁺ ranging from 10⁻¹⁰ to 10⁻⁹ cm² s⁻¹ were estimated from electrochemical experiments for the new composite material based on vanadium pentoxide xerogel and carbon nanotubes synthesized using freeze-drying technology demonstrating that it can be used in cathodes for advanced lithium-ion batteries.
