Three-Dimensional Nanopore γ′-V2O5 Architectures Enabling Stable, Long-Life, High-Power Sodium-Ion Microbatteries

Abstract A three-dimensional nanoscale architecture originating from semiconductor manufacturing offers a powerful route to overcome ion-transport limitations in microscale electrochemical systems. Here, we report a sodium-ion microbattery array based on a coaxial γ’-V2O5/Pt nano...
