abstract = {High-entropy sulfides/selenides are expected to be promising anode materials for lithium-ion batteries due to their unique advantages, such as improved electrical conductivity, component adjustability and structural stability. However, the complexity of their preparation makes the morphology/structure regulation of the high-entropy sulfides/selenides more challenging, thus hindering their application in energy storage. In this paper, high-entropy sulfides/selenides with a special yolk–shell structure is designed through a high-entropy precursor vulcanization/selenization strategy. The high-entropy precursors with yolk–shell structure are first prepared by a simple low-temperature solvothermal method, which are transformed to yolk–shell structured high-entropy sulfide ((CrMnFeCoNi)S2) and selenide ((CrMnFeCoNi)Se2) by an upstream gas method. Not only do the high-entropy sulfide has a weak short-range order, increasing the ion diffusion channel, but the yolk–shell structure also provides many benefits for lithium-ion batteries, such as enhancing the stability, increasing the ion diffusion rate, and easing the volume expansion. The (CrMnFeCoNi)S2 electrode exhibits impressive high specific capacity and long cycle life (1375.8 mAh·g−1 after 1250 cycles at 1 A·g−1), and excellent rate capability (1310.6 mAh·g−1 at 2 A·g−1). This research opens a new window of opportunity for developing the next generation of high-entropy compound electrodes for lithium-ion batteries.}
