[2] The present invention relates to a method of manufacturing a negative electrode of a lithium secondary battery in the initial rain may reduce the negative sequence. BACKGROUND [3] Recently, increasing interest in energy storage technology. Mobile phones, camcorders and notebook PC, furthermore there is a commitment to research and development of electrochemical devices embodied as applications are increasingly extended to the electric vehicle energy. The electrochemical device is a field most attention in this respect. Particularly, development of rechargeable secondary batteries has been the focus of attention. Recently, research and development for the design of new electrodes and batteries to improve the procedure proceeds in developing such a battery, capacity, density and specific energy. [4] Developed in the early 1990s from the secondary batteries that are currently being applied to the lithium secondary battery has an aqueous solution in the form of Ni-MH, using the electrolytic solution Ni-Cd, sulfuric acid - a high operating voltage as compared to conventional batteries such as lead battery, the energy density significantly It has been highlighted as a large advantage. However, of these lithium ion secondary batteries have a safety problem exists, such as ignition and explosion to follow in using the organic electrolytic solution, and a demanding manufacturing drawbacks. Recent lithium polymer secondary battery is to improve the weak points of such a lithium ion secondary battery, but counted as one of next-generation batteries, relatively low and is still capacity to the battery compared with the lithium ion secondary battery, especially the discharge capacity at a low temperature and insufficient the two improvements are urgently needed. [5] The negative electrode material for high capacity and the need to increase it in order, so that the metalloid substance, such as a large Si-based, Sn-based theoretical capacity has been applied as an anode active material. In particular, Si-based materials have been in had a more than 11-fold greater dose (4190 mAh / g) than the theoretical capacity (372 mAh / g) a carbon-based negative active material having the spotlight as materials to replace the carbon-based negative electrode active material. However, these cathode active material has a tendency that the cycle characteristics are lowered, because the lithium ion to the volume expansion of the insert when material is more than three times, the cell capacity reduction slows the charge and discharge proceed in accordance with progress in the charge and discharge repeated, safety in order to commercialize the problem also requires a lot of technology. [6] Thus, silicon oxide (SiO x may wish to study the relaxation cycle characteristics and the volume expansion is conducted using a semi-metal oxides, etc.). A Si-based composite of them, findings using a Si-based material and the carbon-based material is at the same time, silicon is a method designed to minimize the volume expansion of the material to increase the high capacity and the charge and discharge life at the same time. The basic complex synthesis method is used to cover the carbon to silicon-based material. This improved electrochemical properties for the electric conductivity, and an electrolyte between the active material particles and ohjiman reduces the volume expansion of the silicon particles resulted in increased battery life, the initial charge-discharge efficiency due to the formation of the non-reversible according to the silicon-based material during the initial charge and discharge this is an issue to be lowered. [7] In order to compensate for this, when the semi-metal oxide is used to pre-complexed with the metal oxide and lithium given to contain lithium, such as the initial charge-discharge when lithium oxide, lithium metal oxide of the cell ratio is therefore generate less the reverse phase of the negative electrode active material It can increase the initial efficiency.

Like reference numerals designate like elements was omitted, the portion not related to the description in order to clearly describe the present invention, throughout the entire specification. Also, the size and relative sizes of the components shown in the figures may be reduced or exaggerated for clarity of illustration, and are independent from the actual scale. [21] [22] The present invention relates to a method of manufacturing a negative electrode containing a complex of lithium and a negative electrode active material. Preferably, the negative active material may include a semi-metal oxide, wherein the cathode may comprise a complex of lithium and metalloid oxide. The term "metalloid" as used in the present invention is, it may be to mean a metal or metalloid. [23] When used as a negative electrode containing this complex in the lithium secondary battery, as the driving of the cell starts a lithium and a negative electrode active material contained in the complex, e.g., the lithium and metalloid oxide before lithium to produce the alloying ( It is pre-lithiation). Accordingly it is presented lithium alloy that can be charged and discharged the battery in the previously generated status in progress, and as a result, since such as the initial charge and discharge when lithium oxide, lithium metal oxide battery ratio generates less reverse the initial efficiency of the negative electrode active material It can be improved. [24] [25] 1 is a schematic diagram showing a manufacturing method of a lithium secondary battery negative electrode according to the present invention. Figure 1 illustrates a semi-metal oxide as an anode active material to form a complex with lithium, but the invention is not limited to this. [26] Referring to Figure 1 the present invention in detail: i) preparing a lithium metal powder 11 and to the lithium dispersion 10 dispersed in a binder in a dispersion medium; ii) a step of coating on a surface of lithium dispersion (10), the transfer film 20 is formed of lithium metal powder (11) a coating layer; Preparation of lithium secondary battery negative electrode comprising a; and iii) forming a complex of the lithium metal powder (11) after contact with the one surface of the semi-metal oxide (30) a coating layer, rolled to lithium and metalloid oxide (30) there is provided a method. [27] [28] Hereinafter, a method of manufacturing a lithium secondary battery anode of the present invention will be described in detail for each step. [29] [30] i) Lithium dispersion prepared steps [31] First by dispersing the lithium metal powder and a binder in a dispersion medium to prepare a lithium dispersion. [32] The lithium metal powder and the particle size is greater than 0 ㎛, preferably not more than 100 ㎛, and more preferably from 0 ㎛ than, less than 50 ㎛. If exceeding 100 ㎛, thickening the thickness of the electrode after the transfer may cause a problem of low energy density of the entire battery. [33] The binder is polyvinylidene fluoride-hexafluoropropylene (polyvinylidene fluoride-co-hexafluoro propylene, PVDF-co-HFP), polyvinylidene fluoride-trichloroethane to ethylene (polyvinylidene fluoride-cotrichloro ethylene), poly vinylidene Ride-chloroethylene trifluoroacetate (polyvinylidene fluoride-cochlorotrifluoro ethylene), polymethyl methacrylate (polymethyl methacrylate), polyacrylonitrile (polyacrylonitrile), polyvinylpyrrolidone (polyvinylpyrrolidone), polyvinyl acetate (polyvinylacetate), ethylene vinyl acetate copolymers (polyethylene-co-vinyl acetate), polyethylene oxide (polyethylene oxide), cellulose acetate (cellulose acetate), cellulose acetate butyrate (cellulose acetate butyrate), cellulose acetate propionate (cellulose acetate propionate), cyano ethyl pullulan (cyanoethylpullulan), cyanoethyl Polyvinyl alcohol (cyanoethylpolyvinylalcohol), cyanoethyl cellulose (cyanoethyl cellulose), cyanoethyl sucrose (cyanoethyl sucrose), pullulan (pullulan), carboxymethyl cellulose (carboxyl methyl cellulose, CMC), acrylonitrile-styrene-butadiene 1 kinds or more selected from the group consisting of copolymers (acrylonitrile-styrenebutadiene copolymer), polyimide (polyimide), polyvinylidene fluoride (polyvinylidenefluoride), polyacrylonitrile (polyacrylonitrile), and styrene-butadiene rubber (styrene butadiene rubber, SBR) can. [34] [35] The dispersion medium is not particularly limited, and the dispersion can be made uniform by this, it is preferred that can be easily removed later. For example, the dispersion medium is N- methyl-2-pyrrolidone (NMP), dimethylformamide (DMF), dimethylacetamide, xylene, heptane, hexane, toluene, acetone, tetrahydrofuran, methylene chloride, chloroform, cyclohexane and it may include dichloromethane, dimethylsulfoxide, acetonitrile, at least one member selected from the group consisting of pyridine and amines. [36] [37] The lithium metal powder and a binder is that a weight ratio of 70: The mixture to be 5: 30 to 95. If the content of the lithium metal powder is more than than this range, relatively be the content of the binder adhesive force on the transfer film after the step lowering reduced and, on the other hand if the content of the lithium metal powder is lower than the above range, since the step of alloying there is the initial efficiency can be lowered by the lack of amount of lithium in the step. [38] [39] May also be included a suitable amount enough to give the viscosity and fluidity of the dispersion medium to the extent that the mixture can be spray-dried coated on the transfer film. [40] For example, the dispersion medium may be included in 10 to 40% by weight based on the total weight of the lithium dispersion, preferably from 15 to 35% by weight, more preferably 20 to 30% by weight. If it is less than the above range is increased, the viscosity of the lithium dispersion and fluidity are lowered and the coating can be difficult, and if the viscosity exceeds this range reduction can not be also made to facilitate the coating process. In addition, the amount of the lithium is relatively decreased can not be made well before the lithium battery upset when driven at any time. [41] [42] For forming a lithium dispersion in a mixture of the lithium metal powder, binder and dispersion medium, there is used a generally balancers known in the art, the lithium metal powder can be distributed. As the dispersing apparatus, if the device to be distributed to the material dispersed in a dispersion medium not particularly limited, and examples that can be used are an ultrasonic dispersing device, for example, a shaker (shaker), agitator (stirrer) and the like. [43] [44] ii) the lithium metal powder coated with the transfer film manufacturing step [45] Next to the spray for manufacturing the lithium dispersion onto the transfer film to be coated on the lithium metal powder. [46] [47] The transfer film can be used a thermoplastic resin or thermosetting resin for example, various, preferably a thermoplastic resin in that it has a flexibility. Thermoplastic resins may be selected from the group consisting of polyolefins, polyvinyl alcohol-based polymer, polyester, polyamide, polyimide, polycarbonate, polyphenylene ether, polyphenylene sulfide and cellulose derivatives, the balance between heat resistance and flexibility is excellent in point, polyester, polyimide is preferred. [48] [49] The method of coating the above prepared lithium dispersion on the transfer film can be preferably carried out by spray drying (spray dry). The spray-drying to substantially remove water can make a granulated powder. Equipment for performing such spray-drying is substantially connected to the drying chamber in which spray-drying is carried out, the drying chamber connected to the hot air inlet tube and said drying chamber for removing the dispersion medium by supplying hot air into said drying chamber and an air outlet for discharging the cooling air during the spray drying, the material injection pipe, and wherein the drying chamber is connected to the drying chamber so that through the walls forming the drying chamber to the spray by supplying raw material into said drying chamber It is achieved, including the powder recovery pipe for recovering the powder formed by spray drying in a, but is not limited to this. [50] [51] In one example, the spray, but can be performed while spraying the mixed solution to 15 to 25cc / min speed entrance (inlet) at a temperature of 200 to 250 ℃ and exit (outlet) temperature 60 to 80 ℃ in the drying chamber of the spray-drying equipment, this is not limited. [52] [53] iii) complexing step of lithium and a negative electrode active material [54] Next, it rolled to form a complex of lithium and a negative electrode active material after the lithium metal powder coating layer formed on one surface of the transfer film in contact with the negative electrode coating portion. Preferably, the negative active material may include a metalloid oxide.
