| 开发高容量、高倍率和稳定循环性能的新型锂离子电池负极材料是当前锂离子电池领域的研究热点。Lindqvist型多金属氧酸盐作为一类经典的六核同多酸，具有可逆的多电子氧化还原特性，从而在能源领域展现出潜在的应用价值。本研究利用间苯二酚杯[4]芳烃配体(TMR4A)、同多钼酸盐和金属离子(Mn2+或Ni2+)自组装获得的两例已知的Lindqvist型钼多酸-杯[4]芳烃无机-有机杂化配合物，即[Mn(TMR4A)(H2O)4]·[Mo6O19]·0.5CH3CH2OH·H2O (1-Mn)和[Ni(TMR4A)(H2O)4]·[Mo6O19]·0.5CH3CH2OH·H2O (1-Ni)，与还原氧化石墨烯(RGO)复合，获得两种复合材料1-Mn@RGO和1-Ni@RGO。并首次将两种复合材料作为锂离子电池负极材料开展了电化学性能研究。研究发现，1-Mn@RGO和1-Ni@RGO展现出优异的电化学性能和良好的循环稳定性，是一类极具应用前景的锂离子电池负极材料。 |

| Exploring new anode materials with high capacity, high rate performance and stable cycle performance is the research hotspot in the field of lithium-ion batteries (LIBs). As a class of classical hexanuclear isopolyacid, Lindqvist-type polyoxometalates (POMs) possess reversible multi-electron redox property, thus showing potential application value in the field of energy. In this study, two composites 1-Mn@RGO and 1-Ni@RGO were synthesized by the combination of reduced graphene oxide (RGO) and two reported Lindqvist-type isopolymolybdate-resorcin[4]arene-based inorganic-organic hybrid complexes, namely, [Mn(TMR4A)(H2O)4]·[Mo6O19]·0.5CH3CH2OH·H2O (1-Mn) and [Ni(TMR4A)(H2O)4]·[Mo6O19]·0.5CH3CH2OH·H2O (1-Ni), which were self-assembled of resorcin[4]arene (TMR4A), isopolymolybdate and metal ions (Mn2+/Ni2+), respectively. The electrochemical properties of the two composites as anode materials for LIBs were studied for the first time. It was found that 1-Mn@RGO and 1-Ni@RGO exhibited excellent electrochemical performance and good cyclic stability, which made them a type of highly promising anode materials for LIBs. |
