Abstract: CuSbS 2 was tested as a negative electrode material for sodium-ion batteries. The material synthesized by ball milling offers a specific charge of 730 mAh g −1 , close to the theoretical value (751 mAh g −1 ), over a few cycles. The reaction mechanism was investigated by means of operando X-ray diffraction, 121 Sb Mössbauer spectroscopy, and Cu K-edge X-ray absorption spectroscopy. These studies reveal a sodiation mechanism that involves an original conversion reaction in two steps, through the formation of a ternary phase, CuSb (1−x) S (2−y), as well as a Na x S alloy and Sb, followed by an alloying reaction involving the previously formed Sb. The desodiation process ends with the reformation of the ternary phase, CuSb (1−x′) S (2−y′) , deficient in Sb and S; this phase is responsible for the good reversibility observed upon cycling.
