Influence of electrode design on the electrochemical performance of Li3V2(PO4)3/C nanocomposite cathode in lithium ion batteries

► Synthesis of morphologically defined Li3V2(PO4)3/C-nanocomposites as cathode material in lithium ion batteries. ► Li3V2(PO4)3/C- (i) fibers by electrospinning and (ii) powder by sol-gel method. ► Dependency of the electrochemical performance on composite morphology (nanofiber vs. nanoparticle) and electrode architecture (self-supported vs. film electrode).
