[0024] The present invention provides a flexible electrode material based on a Cu-Zr-Ag-Al-Pd amorphous alloy. The flexible electrode material uses a Cu-Zr-Ag-Al-Pd amorphous alloy as a matrix. The raw materials of the matrix include, by atomic percentage, 25%-35% Cu, 42%-48% Zr, 8%-12% Ag, 8%-12% Al, and 2%-10% Pd. The molecular formula of the amorphous alloy is Cu x Zr y Ag z Al m Pd n , where 25≤x≤35; 42≤y≤48; 8≤z≤12; 8≤m≤12; 2≤n≤10.

[0025] Preferably, the thickness of the amorphous alloy is 5-75 nm.

[0026] The present invention also provides a method for preparing a flexible electrode material based on a Cu-Zr-Ag-Al-Pd amorphous alloy, comprising the following steps: Step 1, raw material preparation: weigh the raw materials with a purity of not less than 99.9% by atomic percentage: Cu, Zr, Ag, Al and Pd, respectively, to ensure low impurity content in the raw materials to avoid adverse effects on alloy properties; according to the target alloy composition, accurately calculate the amount of each metal element to control the atomic percentage to Cu: 25%-35%, Zr: 42%-48%, Ag: 8%-12%, Al: 8%-12%, Pd: 2%-10%, and use a high-precision electronic balance for weighing to ensure that the error is controlled within ±0.01g to ensure the accuracy and consistency of the alloy composition.

[0027] Step 2, master alloy smelting: put the raw materials weighed in step 1 into the copper crucible of the vacuum arc melting furnace, ensure that the vacuum system, water cooling system and arc generating device of the vacuum arc melting furnace are operating normally, and clean the water-cooled copper crucible to prevent impurities from mixing; during smelting, vacuum to 5×10 -3 Pa, and fill with high-purity argon with a purity of ≥99.999%, ensure that the working pressure range is 0.07-0.12MPa, turn on the arc power supply, adjust the current to 100-200A to fully melt and mix the raw materials, and repeat the smelting for 3-5 times, with an interval of 6-10min each time. After the alloy is completely solidified, carry out the next smelting to ensure that the alloy composition is uniform, and obtain the smelted Cu-Zr-Ag-Al-Pd master alloy.

[0028] Step 3, molten metal spraying: the smelted Cu-Zr-Ag-Al-Pd master alloy is transferred to the crucible of the single-roll melt spinning equipment, and the patency of the guide tube is checked, and then the copper roller speed is adjusted to 3000-3500r / min to ensure that the copper roller surface is clean and scratch-free to obtain high-quality amorphous thin strips; at the same time, the air pressure control system is adjusted to stabilize the injection pressure at 0.2-0.5MPa; during the injection operation, the Cu-Zr-Ag-Al-Pd master alloy in the crucible is heated at a heating temperature of 1550-1650°C to completely melt it. When the set temperature is reached and the Cu-Zr-Ag-Al-Pd master alloy is completely melted, the air pressure valve is opened, and the molten Cu-Zr-Ag-Al-Pd master alloy is injected through the guide tube to the surface of the high-speed rotating copper roller using air pressure. The injection distance is 1-3mm. During the injection process, the air pressure, temperature and other parameters are continuously monitored to ensure that the injection process is stable.

[0029] Step 4, cooling into strips: utilizing the high thermal conductivity of the copper roller during continuous rotation, the molten Cu-Zr-Ag-Al-Pd master alloy sprayed onto its surface is rapidly cooled to form an amorphous thin strip, wherein the cooling rate is controlled at 10 5 K / s; by finely adjusting parameters such as the copper roller speed of 3500r / min and the spraying distance of 2mm, the thickness of the amorphous thin strip is accurately controlled at 30-70μm.

[0030] Step 5: Install a collection device under the copper roller and use soft materials to prevent the amorphous ribbon from being damaged during the collection process. After the collection is completed, the amorphous ribbon is quickly transferred to a dry, clean environment and sealed for storage to prevent it from oxidation or moisture, thereby ensuring the performance and surface quality of the amorphous ribbon.
