    摘要： Disclosed is an electrode active material having a core-shell structure, which includes: (a) a core capable of intercalating and deintercalating lithium ions; and (b) a shell including a polymer or an oligomer having a glass transition temperature of 25° C. or less when impregnated with an electrolyte, wherein a surface of the core is coated with the shell. Also, an electrode manufactured by using the electrode active material and a secondary battery including the electrode are disclosed. The shell (b) suppresses the formation of an SEI layer during initial charge of a battery, and prevents initial capacity reduction. Accordingly, it is possible to achieve a high capacity battery. The electrode active material having a core-shell structure, specially a metal (loid) based electrode active material having a core-shell structure can have a slightly higher electric capacity, compared to a conventional electrode active material, specially a conventional metal (loid) based electrode active material, and can minimize gas generation during charge/discharge.

    摘要： 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.

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 SnP0-94 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.
