Rate mechanism of vanadium oxide coated tin dioxide nanowire electrode for lithium ion battery

Working mechanism of V2O5 coated SnO2 nanowire electrode for Li-ion batteries with high rate performance is proposed based on operando TEM study to further design high performance compositional materials. Layered V2O5 as shell provides fast Li-ion and electron transport route while well dispersed Sn nanoparticles confined in coating layer that introduced by pre-charge at high rate as core provides high capacity.206
