Recent Advances in Nanowire‐Based, Flexible, Freestanding Electrodes for Energy Storage.

The rational design of flexible electrodes is essential for achieving high performance in flexible and wearable energy‐storage devices, which are highly desired with fast‐growing demands for flexible electronics. Owing to the one‐dimensional structure, nanowires with continuous electron conduction, ion diffusion channels, and good mechanical properties are particularly favorable for obtaining flexible freestanding electrodes that can realize high energy/power density, while retaining long‐term cycling stability under various mechanical deformations. This Minireview focuses on recent advances in the design, fabrication, and application of nanowire‐based flexible freestanding electrodes with diverse compositions, while highlighting the rational design of nanowire‐based materials for high‐performance flexible electrodes. Existing challenges and future opportunities towards a deeper fundamental understanding and practical applications are also presented. Bend and stretch: Nanowires represent very promising candidates for constructing freestanding electrodes with high energy/power densities and excellent flexibility. Recent progress in fabrication methods and design strategies for nanowire‐based, flexible, freestanding electrodes towards high‐performance energy storage is summarized here. [ABSTRACT FROM AUTHOR]
