Three‐dimensional interconnected vanadium pentoxide nanonetworks as cathodes for rechargable lithium batteries are successfully synthesized via a quick gelation followed by annealing. The interconnected structure ensures the electron transport of each unit. And their inner porous structure buffer the volume change over long‐term repeated lithium ion insertion/extraction cycles, leading to the high‐rate long‐life cycling performance.
