Mechanical activation (MA) of the LiOH ุ V 2 O 5 and Li 2 CO 3 ุ V 2 O 5 mixtures followed by brief heating at 673 K was used to prepare dispersed Li 1ุx V 3 O 8 . It was shown that structural transformations during MA are accompanied by reduction processes. EPR spectra of Li 1ุx V 3 O 8 are attribu

EPR spectroscopy is used to study the electronic state of vanadium ions in HT-and LT-Li 1ุx V 3 O 8 . It is shown that in both cases the EPR spectra observed are attributed to vanadyl VO 2ุ ions (localized electron centers) with weak exchange interaction. The other type of registered electrons is ch
Na , +xV,O, has been synthesized with a simple precipitation technique. Its performance as a cathode for rechargeable Li cells is far superior to that of the analogous material prepared at high temperature in terms of specific capacity and rate capability. As a result of the possibility of intercala
