The subject of invention

[0001] This invention relates to a reinforced fabric membrane separator for use in electrochemical devices.

The level of technology

[0002] In patent document EP-A-0232 923 described a method of manufacturing monophonically aperture containing organic fabric embedded in a film-forming mixture comprising a dispersed hydrophilic inorganic material and an organic polymer binder; and the method comprises the following steps: mixing inorganic hydrophilic material with a solution of a polymeric binder in an appropriate solvent to form a suspension; evenly distribute the suspension in an inert flat surface with the formation of the sheet, whose thickness in the wet state is less than 2 mm; immerse woven or non-woven tensioned fabric of any type in a wet sheet; removing the solvent by evaporation and/or leaching hold fabric taut; remove the sheet with the specified surface. The method is performed in the horizontal direction, and organic fabric applied after the distribution (casting) of the sheet in an inert flat surface (glass plate). In practice, a combination of (horizontal) distribution of the suspension in an inert flat surface with subsequent plush is the group stretched organic fabric receive the product, in which the fabric is embedded unsatisfactory (carefully only in the middle part). Almost always the fabric is on one side of the diaphragm, which leads to undesirable accumulation of gas bubbles when using a membrane, for example, in the separator.

[0003] in Addition, a necessary condition for the opportunity to immerse tensioned fabric of any type is the use of suspensions with low viscosity. This inevitably leads to the formation of undesirable asymmetric porous structure, in which the membranes have both sides of various porous structure and a different pore size. Thus the top side in the manufacture (the shiny side of the finished product) will always be the most dense and dull side (the lower side in the manufacture always more loose. In addition, this process is very time consuming and uneconomical method of manufacture, as it cannot be implemented continuously.

[0004] In patent document EP-A-0692830 described method of extruding thermoplastic sheet (300 μm thick), consisting of a mixture containing, by weight, approximately 16.6% of a synthetic polymer (e.g. polyethylene), 66.6% of inorganic powder (e.g., SiO2) and 16.6% of a pore-forming substances (paraffin oil). To one side of the extruded thermoplastic sheet (located in polurasplavlennoy the state) attach inorganic sheet (thickness 200 μm), containing by weight 80% inorganic material (fiberglass) and 20% polyene mass as an organic binder, forming a laminate (laminate). This laminate is then utverjdayut under pressure to align the semi-molten sheet and cooled down to remove pore-forming substance with the formation of the separator coated with the inorganic material. Thus, there is disclosed a dry and continuous extrusion process in which two materials "connected" through lamination.

[0005] In patent document US 4707265 described apparatus for the impregnation of the fabric in which the fabric serves vertically between flatting rollers through the applied solution. Then the membrane is directed between the molding drum and the forming spatula through the bath cooling. When using such a system cannot be made symmetric membrane, so that one side of the cloth facing the bath for cooling, and the other to the drum. The membrane is formed in such a system, is on the side of the cooling pores smaller than on the side of the drum. In addition, as stated in the document, in the manufacture of the described system can be easily occurs so-called "Terry floor", which can only be avoided by changing the coating thickness and the distance between the molding drum and the forming spatula. Because this is about restrictions, it is very difficult to produce a membrane in a wide range of thicknesses.

[0006] In patent document US 2940871 described method of coating canvas plastic composition. Polymer dispersed system is applied in the form of a coating on a carrier tape and heated to melt thermoplastic components of the dispersed system. Then the matrix is removed in a bath of solvent, and the resulting sheet from the coating is dried and stored. Due to the vertical and upward link can only be used relatively viscous dispersed system (otherwise they will run down the carrier tape before you get in the heating device), which leads to a small range of thicknesses. In addition, it is difficult to control the pore size of the final membrane, since it is determined mainly by the composition and method of mixing the dispersed system. Therefore, the parameters have not be the same throughout the membrane. In addition, relatively difficult to control the heating process, and it is more expensive compared to the coagulation process in the quenching bath.

[0007] There is a need for symmetric reinforced canvas diaphragm separators, in which the cloth neatly embedded in the diaphragm and is not acting on its surface. In addition to the process of this production was economically viable, it must be continuous. Further, it should be possible manufacture of the men with different sizes and the same properties on the entire surface of the diaphragm.

A symmetric process is a process that performs equally to both sides of the membrane. This results in a membrane with symmetrical characteristics. Preferably, each step was also performed for both sides at the same time and with the same value of the exposure time (e.g., time of exposure to water vapor or the exposure time in the coagulation bath).

[0010] the Method according to this is the overarching invention preferably further comprises the following steps: one-way reinforced fabric membrane separator provided with a lining and reinforced by a cloth membrane separator with the specified lining wound into a roll. For winding into a roll membrane separator together with lining facilitates flushing of the membrane, especially when using corrugated lining, which is essential liquids on the surface of the membrane at the dive roll.

[0012] the Step of coating according to this invention is preferably performed by sending the blade through a system of double-sided coating with automatic feed of the paste.

[0013] Preferably, the step of steam formation on the surface was performed symmetric treatment of both sides covered with a paste of leaf water steam phase (for example, water vapor or "cold steam" blanket).

[0014] the coagulation Step is preferably performed by a symmetric treatment of both sides covered with paste works in the coagulation bath containing water and an aprotic solvent selected from the group consisting of N-organic (NMP), dimethylformamide (DMF), dimethylsulfoxide (DMSO), dimethylacetamide (DMAc)), aqueous solutions of water-soluble polymers selected from the group contains hydrophobically (LDCs), carboxymethylcellulose (CMC), polyvinylpyrrolidone (PVP), polyvinylpolypyrrolidone (PVPP), polyvinylalcohol (PVA)or a mixture of water and alcohol (e.g. ethanol, propanol and isopropanol). Preferably, the bath temperature of coagulation was from 40°C to 90°C.

SUBSTANCE: novelty is that acid vanadium electrolyte liquor that has in its composition V+3 and V+4 in desired concentration ratio introduced in electrolyte solution is produced from solid vanadium pentoxide by electrochemical method while at least partially reducing dissolved vanadium in acid electrolyte liquor; for the purpose electrolyte liquor is circulated through plurality of cascaded electrolyzers at least partially to V+3 degree; in this way reduced vanadium incorporating electrolyte liquor leaving the last of mentioned electrolyzers enters in reaction with stoichiometric amount of vanadium pentoxide to produce electrolyte liquor incorporating in effect vanadium in the V+3 form; acid and water are introduced to ensure definite molarity of liquor and the latter is continuously circulated through cascaded electrolyzers; stream of electrolyte liquor produced in the process that incorporates V+3 and V+4 in desired concentrations is discharged at outlet of one of electrolyzers of mentioned cascade. Each electrolyzer is distinguished by high degree of asymmetry and has cathode and anode of relevant surface morphology, geometry, and relative arrangement for setting current density on anode surface exceeding by 5 to 20 times that on projected cathode surface, oxygen being emitted from anode surface. Asymmetric electrolyzer of this type can be used in one of electrolyte circuits, positive or negative, of operating battery (cell) for reducing balance of respective oxidation degrees of their vanadium content.
