    • Disclosed are an electrode active material, having a composition of SnPx (0.9≦x≦0.98), an electrode comprising the same, and a lithium secondary battery comprising the electrode. Also disclosed is a method for preparing an electrode active material having a composition of SnPx (0.9≦x≦0.98), the method comprising the steps of: preparing a mixed solution of a Sn precursor, trioctyl phosphine (TOP) and trioctyl phosphine oxide (TOPO); and heating the solution. The application of the teardrop-shaped single-crystal SnPO-94 particles as an anode active material for lithium secondary batteries can provide an anode having very excellent cycling properties because the active material has a reversible capacity, which is about two times as large as that of a carbon anode, along with a very low irreversible capacity, and it is structurally very stable against Li ion intercalation/deintercalation in a charge/discharge process, indicating little or no change in the volume thereof.
    • 公开了具有SnPx(0.9& NlE; x< lE; 0.98)组成的电极活性材料,包括该电极活性材料的电极和包含该电极的锂二次电池。 还公开了一种制备具有SnP x(0.9& NlE; x≦̸ 0.98)组成的电极活性材料的方法,该方法包括以下步骤:制备Sn前体,三辛基膦(TOP)和三辛基氧化膦 (TOPO); 并加热溶液。 作为锂二次电池的负极活性物质的泪珠状单晶SnPO-94颗粒的应用可以提供具有非常优异的循环性能的阳极,因为活性材料的可逆容量大约是可逆容量的两倍 的碳阳极,以及非常低的不可逆容量,并且在充电/放电过程中对Li离子插层/脱嵌结构非常稳定,表明其体积几乎没有变化或没有变化。
