摘要：

After the successful electrochemical intercalation of C-60 with sodium, we report here the preparation of novel negative electrodes for Na-ion batteries composed by commercial C-60:C-70 mixture, this being significantly less expensive than pure fullerenes. An optimized solid-state Na-poly(ethylene oxide) electrolyte was used for the battery assembly. While pure C-60 electrodes show a strong irreversible behavior after the first discharge, the peculiar disordered crystalline arrangement of C-60 and C-70 in the mixture, increased by a high-energy ball milling treatment, allows to improve the specific capacity at the first discharge up to 320 mAh/g, as well as the overall reversibility.
