Li3V2(PO4)3-Based Cathode Materials for Li-Ion Batteries: Time Evolution of the Vanadium Valence State
Li 3 V 2 (PO 4 ) 3 -based composites as a lithium-ion battery cathode material were synthesized by the hydrothermal method with subsequent annealing in an Ar atmosphere. The as-prepared samples were characterized by X-ray diffraction analysis and electron spin resonance (ESR) methods. Based on ESR,...
