Microscopic electrostatic funnel in nanowire-supported island CuGeO₃/VO₂ heterostructures for high-rate lithium storage.
Ternary copper germanate (CuGeO₃) is a promising high-capacity anode for lithium-ion batteries, yet its practical application is limited by sluggish interfacial reaction kinetics and poor intrinsic conductivity. Herein, a nanowire-supported island CuGeO₃/VO₂ heterostructure was constructed through sequential hydrotherm...
