[3] [4] [Technology] [5] The present invention relates to a secondary battery, the binder composition, an electrode slurry composition including the same, an electrode and a secondary battery, and more particularly, it is possible to prevent the rolling roll contamination, binder secondary low adhesion reduction cell according to the rolled length composition and relates to an electrode slurry composition, electrode and secondary battery comprising the same. [6] BACKGROUND [7] Recently, represents a and rapidly increasing, and such a secondary battery of high energy density and operating potential demand for secondary batteries as an energy source, as a portable computer, a portable telephone, an increase technology development and need for a portable apparatus such as a camera cycle life the long self-discharge rate is a number of studies been performed for low lithium secondary batteries, are also commercially available and widely used. [8] In general, the electrode of the lithium secondary battery is generally prepared by dispersing in a solvent and mixed with a binder, conductive material, the positive electrode active material or negative active electrode to create a slurry and rolled by applying it onto the surface of the electrode current collector and dried. [9] The binder is active material and the active material, and between the active material and to be used to ensure adhesion or gyeolchakryeok between the electrode current collector, a secondary battery, the binder materials that are currently commercially available is of polyvinylidene fluoride (PVdF), styrene-butadiene rubber (styrenebutadiene rubber: and the like CMC): SBR) / carboxymethylcellulose (carboxy methyl cellulose. [10] By the way, there is a problem if the dispersion of the binder decrease, and the viscosity of the electrode slurry increases rapidly that the coating is difficult. This problem appears even more severe in the case where the solvent is an aqueous slurry of the electrode. Thus, there is used a method of adding an emulsifier at the time of producing the binder to improve the stability of the binder used in the aqueous slurry. If the content of the emulsifier may increase the stability of the binder increases This suppresses the slurry viscosity increase. [11] However, the emulsifier due to its lower molecular weight than the other components, the use of a binder containing an emulsifier in excess, the low molecular weight emulsifiers by the frictional heat generated in the electrode-rolling process to easily migrate to the surface sikindaneun contaminate the rolling rolls there is a problem. The emulsifier attached to the rolling roll is attached so keep on rolling roll by the force caused by the pressure that the rolling roll do not fall easily. On the other hand, emulsifier because it has tackiness, if such emulsifying agents are still attached to the rolling roll, is attached to the other components of the electrode layer vary in the rolling rolls, thereby intensifying the contamination. When thus using the contaminated calender roll to proceed without the rolled electrode is uniformly rolled, there is a problem in that the electrode surface is unevenly formed. [12] Further, in recent hold the rolling process to increase the electrode density, or a method such as that carried out in multiple stages has been proposed. However, in the case of a secondary battery binder used in the prior art, there is a problem in that the elimination and / or may result in such detachment of the active material layer of the electrode material by the rolling process increases the surface adhesion of the binder decreases.

[52] [53] The latex particles (A) can be produced by polymerization using conventional polymerization processes known in the art, the monomer mixture containing the components as described above. For example, the latex particles (A) can be produced by a method of emulsion polymerization by adding an emulsifier to the monomer mixture. [54] The polymerization temperature and polymerization time may be properly determined depending on the kind of the polymerization method, polymerization initiator, for example, the polymerization temperature may be 50 to 200 ℃ ℃, the polymerization time may be from 1 to 20 hours. [55] Further, the polymerization initiator as needed, at the time of the polymerization, an activator, a crosslinking agent, a chain transfer agent, etc. may be further added. [56] The polymerization initiator useful to include may be used are inorganic or organic peroxides, e.g., potassium persulfate, sodium persulfate, ammonium persulfate, etc. and water-soluble initiators, including, cumene hydro peroxide, benzoyl peroxide, etc. You may use the initiator.

If the filtration residue of the latex particles is satisfied the above range, the entire gyeolchakryeok and when the current collector coating uniformity and the house can be further improved. [62] Latex particles having a filtration residue content of the latex particles satisfying the above range is, for example, without having to input all of initially the raw material monomer in the polymerization, employ a method of continuously added to, or after the latex particles polymerized It may be prepared by carrying out a filtration treatment using diatomaceous earth as a filter aid, but is not limited to this. [63] [64] (B) an emulsifier [65] The emulsifier, to be added to the emulsion polymerization reaction of the latex particles (A), and a substance having a hydrophilic group (hydrophilic) group and a hydrophobic (hydrophobic) at the same time, it is not the type that is particularly limited. [66] For example, the emulsifier is oleic acid, stearic acid, lauric acid, fatty acid salt, represented by such as sodium or potassium salts of the mixed fatty acid system, or sulfate, common anions such as sulfonate, phosphate, and sulfosuccinate St. emulsifiers etc. this can be used there. [67] [68] According to studies by the present inventors, if the emulsifier content in the binder composition satisfy a specific range, as well as to prevent the rolling roll contamination, showed that the effect of preventing the deterioration of adhesion to the rolling length. [69] Specifically, the binder composition according to the present invention includes the emulsifier to 3000ppm, preferably less than 500ppm to 2500ppm, based on 100 parts by weight of latex particles. If there is more than 3000ppm, the content of the emulsifying agent was the contamination of the rolling rolls caused, there is a problem that the adhesive force is significantly reduced if the increase in length of rolling. [70] [71] On the other hand, the binder composition of the present invention is to improve the physical properties of the binder, may further include additive components in addition to the above components. The additives include, for example, (please base material if the additive that may be included in addition to the binder composition), antioxidants, preservatives, and the like. In particular, the antioxidant may be preferably used to prevent the deterioration of the latex particles in cell operation due to the softening process, such as gelation.
