Improved electrochemical performances of LiOVPO4/ketjen black composite prepared by a novel solvent-thermal oxidation route
Orthorhombic β-LiVOPO 4 /ketjen black composite is obtained via a two-step chemical synthesis. In the first step, Li 3 V 2 (PO 4 ) 3 -V 2 O 3 /ketjen black precursor is obtained by spray-drying process and subsequent heat treatment. Solvent-thermal oxidation of the precursor results in the complete...
