Originální abstrakt

Hard carbon and tin composites are being investigated as promising anode materials for sodium-ion batteries due to the high theoretical capacity of tin and the structural stability of hard carbon. Cyclic voltammetry reveals distinct alloying/dealloying peaks associated with sodium and tin phases, while initial galvanostatic cycles at 0.1 C show a clear voltage plateau associated with the formation of Na–Sn alloys. However, extended cycling at 0.2 C shows a significant decrease in capacity and suppression of tin-related activity, resulting in performance lower than that of the original hard carbon. These results highlight the potential and limitations of Sn additives and suggest directions for improving electrode design.
