摘要：

Developing high-capacity anodes is crucial for enhancing lithium battery energy density. (3-Mn[N(CN)2]2shows promise as a negative electrode material, delivering high specific capacities (approximate to 500 mAh g-1 over 200 cycles at 100 mA g-1) and superior to graphite (approximate to 372 mAh g-1), involving both cationic and anionic redox processes. Furthermore, we compared the differences in electrochemical performance between the alpha- and (3-Mn[N(CN)2]2, demonstrating that the former exhibits better cycling stability while the latter shows superior rate performance.
