摘要

金属少层 1T 相二硫化钒纳米片已被用于钠离子电池。经过 200 次循环后，在 100 mA∙g-1 的条件下，它可以提供 241 mAh∙g-1 的容量。这种长期稳定性归功于 1T 相中 V 原子间精心设计的二维（2D）电子-电子关联以及优化的平面内电传输所带来的便捷离子扩散和电子传输。我们的研究结果突显了相工程在储能电极设计中的应用。

Metallic few-layered 1T-VS2 nanosheets for enhanced sodium storage

Metallic few-layered 1T phase vanadium disulfide nanosheets have been employed for boosting sodium ion batteries. It can deliver a capacity of 241 mAh∙g⁻¹ at 100 mA∙g⁻¹ after 200 cycles. Such long-term stability is attributed to the facile ion diffusion and electron transport resulting from the well-designed two-dimensional (2D) electron-electron correlations among V atoms in the 1T phase and optimized in-planar electric transport. Our results highlight the phase engineering into electrode design for energy storage.
