Product Introduction:

     Graphene is currently one of the thinnest yet hardest nanomaterials. It is almost completely transparent, absorbing only 2.3% of light. Its thermal conductivity is around 5300 W/m·K, higher than that of carbon nanotubes and diamonds. At room temperature, its electron mobility exceeds 15,000 cm²/V·s, surpassing that of carbon nanotubes or silicon crystals, while its resistivity is only about 10⁻⁶ Ω·cm, lower than copper or silver, making it one of the materials with the lowest resistivity in the world. Due to its low resistivity and high electron mobility, it is expected to be used in developing thinner, faster-conducting next-generation electronic components or transistors. Since graphene is essentially a transparent and excellent conductor, it is also suitable for manufacturing transparent touch screens, light panels, and even solar cells.

Incorporating graphene into battery electrode materials can significantly improve charging efficiency and increase battery capacity. Self-assembled multilayer graphene sheets are not only an ideal design for lithium-air batteries but can also be applied in many other potential energy storage fields, such as capacitors and electromagnetic guns. Additionally, new graphene materials will not rely on platinum or other precious metals, reducing costs and environmental impact.

       Display Industry: Graphene-based transparent electrodes may be one of the fastest achievable applications of graphene. Various displays, such as LCD TVs and camera screens, use transparent electrodes. Displays made with graphene are characterized by being soft, thin, and allowing easy light transmission, reducing the need for overly bright backlighting. Graphene displays can be flexible. Current research on flexible electronic paper struggles with displaying color animations, but graphene displays can overcome this limitation. The dynamic photos in the "Daily Prophet" from the Harry Potter novels may no longer be just a writer's fantasy. Currently, the primary material for transparent electrodes is indium oxide, but its raw materials are nearly depleted. Replacing it with graphene, which is carbon-based, offers an almost limitless resource on Earth.

       Supercapacitors: Microscopic graphene-based supercapacitors charge and discharge much faster than existing devices, contributing to the production of smaller mobile phones. Research also suggests that they could enable rapid charging for phones and cars and reduce the size of certain tools.
