Transition　metal　dichalcogenides　(TMDs)　have　enormous　commercial　potential　as　anode　materials　for　all-solid-state　lithium-ion　batteries　(ASSLIBs).　Herein,　the　copper　sulfides　(CuS)　with　a　hierarchical　nanosphere　structure　are　designed　through　a　facile　one-step　solvothermal　synthetic　route.　When　employed　as　an　anode　for　ASSLIBs,　the　CuS　hierarchical　nanospheres　(hn-CuS)　exhibited　a　high　capacity　of　350　mA　h　g−1　after　50　cycles　at　a　current　density　of　250　mA　g−1　and　an　outstanding　rate　capability.　The　unique　three-dimensional　(3D)　structure　of　hn-CuS　plays　an　important　role　in　alleviating　the　volume　expansion,　thus　obtaining　excellent　electrochemical　properties.　Moreover,　ex-situ　X-ray　diffraction　was　used　to　investigate　the　possible　kinetics　and　reaction　mechanism　of　the　hn-CuS　anode.　This　work　inspired　a　new　promise　for　preparing　the　other　TMDs　as　anode　materials　for　ASSLIBs　with　high　performance.　©　2024　Elsevier　Ltd
