Recently, American researchers have developed a new material that can store and release heat energy on demand. The heat storage device made of this material not only has a large energy storage density, but also has the characteristics of low cost, convenient transportation, and long energy storage time, and is expected to open up a new way of capturing and storing solar energy.
This is a material consisting of azobenzene and carbon nanotubes. In addition to the advantages of difurethylene oxide, it is also characterized by low cost and good thermal stability, and it exceeds the lithium ion battery in terms of energy density.
MIT professor Grossman said: "This material is very effective, but it still has a relatively high energy density. Its advantage lies in the integration of energy capture and storage into a single step that can be accomplished simultaneously with one material. Converting and storing both tasks has the disadvantage of providing only thermal energy instead of electrical energy, but this can be compensated by thermoelectric devices or steam generators.The innovation of the new research is that it creates the possibility to use carbon nanotubes to make this The nano-templates of the materials paved the way for similar studies using other materials in the future."
