Stereoassembled V ₂ O ₅ @FeOOH Hollow Architectures with Lithiation Volumetric Strain Self-Reconstruction for Lithium-Ion Storage

Abstract

<jats:p>Vanadium oxides have recently attracted widespread attention due to their unique advantages and have demonstrated promising chemical and physical properties for energy storage. This work develops a mild and efficient method to stereoassemble hollow V<jats:sub>2</jats:sub>O<jats:sub>5</jats:sub>@FeOOH heterostructured nanoflowers with thin nanosheets. These dual-phased architectures possess multiple lithiation voltage plateau and well-defined heterointerfaces facilitating efficient charge transfer, mass diffusion, and self-reconstruction with volumetric strain. As a proof of concept, the resulting V<jats:sub>2</jats:sub>O<jats:sub>5</jats:sub>@FeOOH hollow nanoflowers as an anode material for lithium-ion batteries (LIBs) realize high-specific capacities, long lifespans, and superior rate capabilities, e.g., maintaining a specific capacity as high as 985 mAh g<jats:sup>−1</jats:sup> at 200 mA g<jats:sup>−1</jats:sup> with good cyclability.</jats:p>

[22,23] A small amount of reports have reviewed the research progress of 3D printed flexible sensors with a brief overview on several specifically functional sensing devices merely. [24,25] The evolution of 3D printed polymer-based flexible strain sensors on materials preparation and device design has not been discussed in depth.…”

Stable Li metal anode in a lithiophilic shuttle

“…5 The latter has been widely addressed by manipulating the electroplating conditions, 6 SEI conductivity and uniformity, [7][8][9] and artificial Li + guiding substrates. [10][11][12][13][14] As one of the most important factors involved in Li electroplating, Li affinity of the plating substrate has shown direct influence on the initial Li nucleation, while ordered Li nuclei are always achieved at the high-Li-affinity interface due to the much lowered Li nucleation overpotential. 15 Representatively, metal oxides, despite the great variety of metallic cations, have shown common high-Li-affinity for dendrite suppression.…”
