Abstract

<abstract abstract-type="main" id="jace13267-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p>Nanosized‐layered rock‐salt LiVO₂ was prepared by a new method from peroxo‐polyvanadic acid. The X‐ray diffraction pattern was well fitted with the space group <italic>R</italic>−3<italic>m</italic> in the Rietveld analysis and the crystallite size was estimated at 47 nm. The electrochemical properties as cathode materials for lithium ion batteries were investigated. The specific capacity of LiVO₂ was greatly improved to 149 mAh/g under the current density of 149 mA/g, in comparison with that of the conventional LiVO₂ below 50 mAh/g prepared by the solid‐state reactions.</p> </abstract>
