The high discharge capacity (ca. 380 mAb g(-1) in the first cycle) and diffusion coefficients of Li+ ranging from similar to 10(-10) to similar to 10(-9) cm(2) 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.
