摘要：

By exploiting the ability of ionic liquids to solubilize molecular sulfur at the melting point, we report the electrodeposition of CuS in an [EMIm]TFSI (1-ethyl-3-methylimidazolium bis (trifluoromethanesulfonyl) imide) electrolytic bath containing Cu (TFSI)(2) salt and elemental sulfur. Single-crystal and preferentially oriented covellite CuS thin films with flake morphology have been successfully obtained. Li/CuS coin cells using the deposits after carbon coating as the positive electrode show a discharge capacity of 350 mA h g(-1) with capacity retention of 54.4% after 20 cycles.
