The title of the invention: Composite and method of manufacturing the negative electrode slurry including the same Art [1] The present invention relates to a method for manufacturing a negative electrode slurry containing this complex and. BACKGROUND [2] Recent miniaturization Fig battery acting as the power source in accordance with the trend of miniaturization and weight reduction of electronic devices and has been upset tendency needs. And a rechargeable battery with high capacity and is small and light lithium-based secondary battery is put into practical use, a small video camera, a mobile phone, has been used for portable electronic devices and communication equipment such as a laptop. [3] The lithium secondary battery has a high energy and high operating voltage and high capacity advantage compared to the other cell as an energy storage device having a power. However, due to such a high energy that is the safety of the battery has problems such as the risk of explosion or fire. In particular, hybrid cars, etc. can be found in the spotlight in recent years is more important, these safety requirements because a high energy and power characteristics. [4] In general, the lithium secondary battery is delivering energy while reciprocating the positive electrode such as to be desorbed again at the positive electrode, negative electrode, and an electrolyte, the lithium ions emitted from the positive electrode active material by first filling the negative electrode active material, that is inserted into the carbon particles discharged this discharge is possible because the role. [5] On the other hand, according to a high-capacity battery is required due to the continued development of the portable electronic device of the high-capacity negative electrode Sn, Si, etc. of much higher capacity than carbon per unit weight is used as a conventional negative electrode material material has been actively studied. This volume expansion becomes large when using the Si or a Si alloy as a negative electrode active material, the cycle characteristics are poor is a problem, use of graphite and mixed in the negative electrode active material in order to solve this problem, however, by the graphite mixed with graphite it is unevenly distributed during use cycle performance, and there is a problem that the life is reduced. Detailed Description of the Invention SUMMARY [6] The present invention provides a composite material and method of producing a negative electrode slurry containing the same contained in the negative electrode active material. Technical Solution [7] The present invention provides a complex comprising a conductive material and a binder on the surface (semi) metal oxide, the (semi) metal oxide. [8] The present invention also provides a method of manufacturing a negative electrode slurry, which comprises producing, mixed and burnt to the composite material substance and a non-aqueous binder, the conjugate to (semi) metal oxide and the mixture was dispersed a conductive material in the water-based binder do. [9] Effects of the Invention [10] The present invention by a conductive material was dispersed in the aqueous binder (semi) mixed with a metal oxide, can improve the electrical conductivity to improve performance, especially lifetime characteristics of the secondary battery. [11] Best Mode for Carrying out the Invention [12] The present invention provides a complex comprising a conductive material and a binder on the surface (semi) metal oxide, the (semi) metal oxide. [13] Composite, according to an embodiment of the invention is then prepared by dispersing a conductive material in an aqueous binder (semi) by mixing with the metal oxide, it can improve the electrical conductivity to improve performance, especially lifetime characteristics of the secondary battery of the secondary battery have. Composite according to one embodiment of the present invention is economical by using a water-based binder as the binder of the negative electrode material, a high capacity can be increased can be the ratio of the metal oxide of the (semi) at the cathode. [14] Wherein the binder is specifically water-based binder, wherein the binder is a styrene-butadiene rubber, acrylonitrile-acrylonitrile butadiene rubber, acrylonitrile-butadiene-styrene rubber, carboxymethyl cellulose and hydroxypropyl 1 is selected from the group consisting of methyl cellulose It may include or more. [15] In addition, the present invention of one embodiment in the accordance with the complex in the (semi) metal oxide is SiO x, AlO x, SnO x, SbO x, BiO x, AsO x, GeO x, PbO x, ZnO x, CdO x, InO x , TiO x , and GaO x (wherein, 0
