Manganese-based layered coordination polymer ([Mn(tfbdc)(4,4'-bpy)(H2O)2], Mn-LCP) with microporous structure was synthesized by reaction of 2,3,5,6-tetrafluoroterephthalatic acid(H2tfbdc) and 4,4'-bipyridine(4,4'-bpy) with manganese(II) acetate tetrahydrate in water solution. Mn-LCP was characterized by elemental analysis, IR spectra, thermogravimetric analysis, X-ray single-crystal structure analysis, and powder X-ray diffraction. Magnetic susceptibility data from 300 to 1.8K show that there is a weak antiferromagnetic exchange between Mn(II) ions in Mn-LCP. As anode material, the Mn-LCP electrode exhibits an irreversible high capacity in the first discharge process and a reversible lithium storage capacity of up to about 390 mA h/g from the fourth cycle. It might provide a new method for finding new electrode materials in lithium-ion batteries.
具有微孔结构的锰基层状配位聚合物([Mn(tfbdc)(4,4'-bpy)(H2O)2],Mn-LCP)是通过 2,3,5,6-四氟对苯二甲酸(H2tfbdc)和 4,4'-联吡啶(4,4'-bpy)与二水合醋酸锰在水溶液中的反应合成的。Mn-LCP 通过元素分析、红外光谱、热重分析、X 射线单晶结构分析和粉末 X 射线衍射进行了表征。300 至 1.8K 的磁化率数据表明,Mn-LCP 中的 Mn(II)离子之间存在弱反铁磁交换。作为阳极材料,Mn-LCP 电极在首次放电过程中表现出不可逆的高容量,并且从第四周期开始具有高达约 390 mA h/g 的可逆锂存储容量。它可能为寻找锂离子电池中的新型电极材料提供了一种新方法。
