In the vast field of materials science, the research, development and innovation of new materials have always been the core driving force to promote scientific and technological progress and industrial development. In recent years, tungsten oxide-based composite materials, with their unique physical and chemical properties and broad application prospects, have gradually stood out among numerous new materials and captured the attention of scientific researchers.

In the high-temperature industry, pure tungsten electrodes have emerged as indispensable core materials in welding, smelting, and plasma technology, thanks to their exceptional physical and chemical properties. As the single metallic element with the highest melting point, tungsten's stability in extreme environments makes it the preferred choice for processing high-melting-point metals and demanding processes.

With the rapid development of technology in today's era, energy-related issues have become increasingly prominent. Energy storage technology, as a crucial link in the energy field, has received unprecedented attention. Supercapacitors, emerging as a shining new star in the energy storage industry, are gradually coming into people's view with their distinctive advantages and broad application prospects, thus becoming the "new darling" in the modern energy domain.

Pure tungsten electrodes, as one of the earliest electrodes used in argon arc welding, have consistently played a significant role in the welding industry. This type of electrode, characterized by its high melting point, high density, corrosion resistance, and excellent electrical and thermal conductivity, has become an indispensable key material under specific welding conditions.
