Description
Technical Field
The invention relates to the technical field of material compounding, in particular to a molten salt diffusion compounding device and a molten salt diffusion compounding method.
Background
The technology of SOFC (solid oxide fuel cell) has potential in the field of power generation. Because the components of the battery component are mainly composed of stable oxides, the operation temperature can be stably used at 650-1000 ℃, and expensive platinum materials are not needed to be used as catalysts for conversion, so that the manufacturing cost of cathode and anode materials for catalysis can be lower. Advantages of using SOFCs as power generation systems include: high power generation efficiency, so NO is generated in the using processx、SOxThe discharge amount of pollutants such as HC and the like is relatively small, so that CO is generated2Are easier to collect. In addition, there are many kinds of fuels that can be used as SOFC fuels, such as natural gas, CO, H2Methanol and coal gas, and even combustible waste gas and other fuels can be utilized. SOFC uses its own high temperature operating environment to reform internal fuel, which simplifies the system. At the output power of 0.3W/cm2Above, the generating efficiency can reach 50-60%, and the generating efficiency of a high-efficiency combined generating system constructed by the high-temperature tail gas discharged by the SOFC and the turbine can reach more than 90%. In addition, the lithium ion batteries in the market currently use a polymer electrolyte or an ionic liquid or a phosphorus-containing flame retardant electrolyte, and an isolating film is needed to separate the electrolyte from an electrode part, so the thermal stability of the isolating film also has an important influence on the safety of the battery, and Polyethylene (PE) is generally used at present, and has a heat-resistant temperature of about 120-130 ℃, and if the operating temperature exceeds 130 ℃, the PE isolating film can be melted through and shrunk, so that the positive electrode and the negative electrode are short-circuited. Therefore, if the electrolyte used by the current lithium ion battery is changed into an inorganic solid lithium ion conductor, part of the isolating membrane can be removed, the problems of possible leakage and corrosion of the electrolyte are solved, and the safety is improved. In addition, if the conductivity and concentration of lithium ions can be effectively improved, the key factors of replacing the traditional lithium ion battery electrolyte system by the inorganic solid lithium ion conductor are provided.
The SOFC is a composite electrolyte material in which an electrolyte oxide and a carbonate are combined, and has O2-、H+With CO3 2-The characteristics of the three ions moving in the electrolyte material, below 500 ℃, exhibit conductivity measurements corresponding to 8YSZ at 750-: 10-2S/cm。
The current commercial cell sheet for SOFC mainly uses NiO-8YSZ//8YSZ// GDC// LSC unit cell manufactured by Elcogen company, and the electrolyte thickness is only about 5 μm. The power density measurement results of the unit cells at 600-: 600 ℃ and about 400mW/cm2(0.6V); 650 ℃ and about 550mW/cm2(0.8V); 700 ℃ and about 600mW/cm2(0.85V). However, the solid carbonate-oxide composite fuel cell with the SDC-C electrolyte thickness of 200 μm, NiO-SDC// SDC-C// LiNiO-SDC, has the same test voltage of 0.85V and the power test data measured at 470 ℃ of 40mW/cm2. In this case, no matter what temperature is measured, the Elcogen cell sheet is about 15 times higher than the low-temperature type composite salt fuel cell in terms of power value only. However, in an alternative view, the solid carbonate-oxide composite fuel cell is of the ESC type (electrolyte supported type), so the current electrolyte thickness is 200 μm, whereas the electrolyte thickness of Elcogen cell sheets is only 5 μm. The relationship between the composite salt fuel cells with different electrolyte thicknesses and the maximum power value measured by the composite salt fuel cells can be observed, and the thickness of the electrolyte directly influences the operation power of the cells. If the electrolyte thickness of the composite salt fuel cell is reduced to 5 μm as compared with the Elcogen cell sheet, it is predicted that the system using the composite material cell will indeed exhibit the potential for developing low-temperature fuel cells.
However, the time required for the electrolyte to be made porous and then to be immersed in the molten carbonate to be combined is extremely long, generally 7 days or more is required, and it is difficult to fill all the pores of the electrolyte substrate.
