Detailed Description
The invention is described in further detail below by means of specific embodiments and with reference to the attached drawings.
Example 1: a preparation method of an all-solid-state flexible thermoelectric conversion device comprises the following steps:
(a) The method comprises the following steps Firstly, bonding a nano porous electrode 1 of 3cm 3mm on a current collector 4 through conductive silver paste 3, wherein the current collector 4 is made of stainless steel foil, and the nano porous electrode 1 adopts a carbon cloth electrode;
(b) The method comprises the following steps Heating a potassium chloride solution to 30 ℃, then slowly adding polyvinyl alcohol particles, adjusting the rotating speed of a magnetic stirrer to be at least 300r/min, heating to 95 ℃, stirring for 30min until the polyvinyl alcohol is completely dissolved, and cooling to room temperature after the polyvinyl alcohol is completely dissolved, wherein the mass ratio of the polyvinyl alcohol to water in the potassium chloride solution is 1;
(c) The method comprises the following steps After the conductive silver paste 3 between the nano-porous electrode 1 and the current collector 4 is dried in the air, pouring the mixed solution containing polyvinyl alcohol and potassium chloride cooled in the step (b) onto the surface of the nano-porous electrode 1 until the mixed solution is completely covered, after the nano-porous electrode 1 fully absorbs the mixed solution, adding the mixed solution containing polyvinyl alcohol and potassium chloride until the solid electrolyte 2 is 1-2 mm higher than the surface of the nano-porous electrode 1, putting the nano-porous electrode into a refrigerator for freezing for 1h, taking out the nano-porous electrode for thawing for 1h at room temperature, and repeating the freezing and thawing for 3-5 times, so that the cross-linking of the mixed solution containing polyvinyl alcohol and electrolyte can be realized, and the flexible solid electrolyte 2 is formed;
(d) The method comprises the following steps Placing the other current collector 4 on the surface of the solid electrolyte 2 in the step (c), pouring a mixed solution containing polyvinyl alcohol and potassium chloride again to cover part of the current collector 4, after cross-linking and curing, respectively connecting the current collectors 4 at the nano-porous electrode end and the solid electrolyte end with leads 6, fixing the leads 6 on the current collectors 4 by welding or bonding, then integrally placing the whole body into a mold with a space of 4cm x 6mm, pouring the prepared silicon rubber packaging material, and placing the silicon rubber packaging material into a 60 ℃ oven for 4h for curing, wherein the silicon rubber packaging material 5 is prepared by a two-component 1:1;
(e) The method comprises the following steps After all the components are packaged, the device and the same device are respectively contacted with a heat source and room temperature, the current collectors 4 in the solid electrolyte 2 of the device and the solid electrolyte are connected, and the current collector 4 in the end of the nano-porous electrode 1 is used as an output end.
Example 2: the difference from example 1 is that "the concentration of potassium chloride solution was 0.05mol/L".
Example 3: the difference from example 1 is that "the concentration of potassium chloride solution was 0.1mol/L".
The thermoelectric conversion devices prepared in examples 1, 2, and 3 were tested for the change in output power with temperature difference upon discharge by the following test methods: the thermoelectric conversion device prepared and an identical device were used to contact heat sources (31 ℃, 36 ℃, 41 ℃, 46 ℃, 51 ℃, 56 ℃, 61 ℃) and room temperature (26 ℃) respectively, to connect the current collectors 4 in the two solid electrolytes 2, and the current collector 4 in the end of the nanoporous electrode 1 was used as an output end.
The principle is as follows: when the two ends of the device are both at room temperature (namely, no temperature difference exists), the absolute value of the output voltage of the device is close to 0mV, when the temperature of the heat source is higher than the room temperature, the solid electrolyte in the device placed on the surface of the heat source is redistributed, the charges adsorbed on the surface of the nano porous electrode move, the induced surface charges of the nano porous electrode are correspondingly increased and decreased, the nano porous electrodes in the two devices generate potential difference at the moment, and if the two electrodes are connected into a circuit, current can be generated.
Thermoelectric conversion efficiencies of thermoelectric conversion devices prepared in examples 1, 2, and 3 were compared: as shown in fig. 2 to 4, the input power of the thermoelectric conversion device is constant under a specific temperature difference, and the average output power of the thermoelectric conversion device changes with the discharge time. It is not reasonable to select the average output power corresponding to a specific discharge time, because the discharge equilibrium time of different systems is different, so the average output power value in a reasonable time range is selected to represent the output power of the device to calculate the thermoelectric conversion efficiency. In view of the fact that the discharge voltage of the thermoelectric conversion devices prepared in the embodiments 1, 2, and 3 is reduced to about 24% of the maximum voltage value at the lowest level after the discharge time is 1s (see fig. 5 to 7), and the output power is low and difficult to use because the subsequent discharge process is slow, the discharge process can be considered to be completed approximately, and the thermoelectric conversion efficiency can be calculated by selecting the average output power corresponding to the discharge voltage reduced to 20% of the maximum value similarly to defining the time constant during the capacitor charge and discharge process.
As shown in fig. 8, the thermoelectric conversion devices prepared in examples 1, 2, and 3 exhibited maximum thermoelectric conversion efficiencies of 0.0025%, 0.017%, and 0.014%, respectively, at a temperature difference of 35 ℃. Overall, the thermoelectric conversion efficiency increases monotonically as the temperature difference increases, and the thermoelectric conversion efficiency of the thermoelectric conversion device produced in example 2 is the greatest and the thermoelectric conversion efficiency of the thermoelectric conversion device produced in example 3 or example 1 is inferior. The thermoelectric conversion device prepared in example 2 had a large output voltage and a relatively small internal resistance, and therefore the thermoelectric conversion efficiency was determined by the solution concentration, the internal resistance of the device, and the output voltage.
Comparative example 1: compared with the embodiment 1, the difference is that the nano-porous electrode 1 adopts a carbon cloth electrode carbon nanotube film.
The graphene film is obtained by carrying out suction filtration on a graphene aqueous solution and then carrying out freeze drying, and the internal structure of the graphene film is mainly formed by spontaneous stacking of graphene sheet layers, so that van der Waals force is mainly acted between the graphene sheet layers, and the contact is weak. The microstructure of graphene is loose, porous and fragile as shown in fig. 9 (a), and the carbon nanotube film and the carbon cloth are formed by winding micro-nano-scale slender filament fibers/tubes in a microscopic manner, so that the carbon nanotube film is high in flexibility and has certain nanopores, and fig. 9 (b) and (c) show the microstructure.
The discharge voltage and current curves of the apparatus prepared according to the methods of comparative example 1 and example 1, in which the maximum value of the discharge voltage curve represents the open circuit output voltage at a constant temperature difference when the temperature difference is 30 c and the carbon cloth is used as an electrode, respectively (see fig. 10 and 11), show that the carbon cloth output voltage is higher than that of the carbon nanotube film at the same area. When the discharge test of the two electrode materials is carried out, the used load resistance is 1k omega, the system internal resistance corresponding to the two electrode materials can be further calculated according to the discharge voltage and discharge current curve, the carbon nano tube film system internal resistance is about 3.20k omega, and the carbon cloth system internal resistance is about 1.03k omega, so that the carbon cloth system internal resistance is small, the internal consumption is low, the output voltage is high, and the thermoelectric conversion efficiency is higher.
In conclusion, all the components of the flexible device are flexible and bendable materials, the whole device finally shows flexibility, and in practical application, the problems of component leakage and the like are not considered in the all-solid-state flexible device, so that the safety coefficient is high; the device is suitable for various heat sources with curved surfaces, can recover and convert low-grade waste heat energy, and provides a new idea for secondary utilization of energy; the device is soft and light, and is convenient to install, carry and transport.
While the present invention has been particularly shown and described with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
