Graphene Powder, because of its extraordinary properties - including superior electrical conductivity, mechanical strength, and thermal stability, is creating new possibilities in applications across a broad spectrum. In this blog post, we discuss the primary applications of graphene powder and why it is so good.
What is Graphene Powder?
Graphene powder consists of graphene, individual carbon atoms in honeycomb form. It is usually produced by processes such as liquid-phase exfoliation, chemical reduction of graphene oxide, or mechanical exfoliation. Powder enables graphene to blend with liquids, plastics, metals, and ceramics and is used in most industries.
Main Uses of Graphene Powder
- Energy Storage and Batteries
Graphene powder is widely used in battery electrodes, especially lithium-ion and lithium-sulfur batteries. It helps to store more charge, increase the ease of electricity flow, and prolong the battery life. Its high surface area and high electrical conductivity allow electrons to move more quickly, leading to quicker charging and more energy storage.
- Supercapacitors
Graphene powder is a unique material used for electrodes in supercapacitors. It enhances power and energy. Its high surface area allows energy to be stored and rapid charge-discharge cycles.
- Polymer and Composite Reinforcement
Graphene powder is an excellent polymer, plastic, and composite filler. It adds strength, stiffness, and durability to these materials. It is applied in automobiles, aircraft, and construction materials to create light but robust parts.
- Conductive Inks and Coatings
Graphene powder is used to make conductive inks because it conducts electricity very well. It is used for printed electronics, RFID tags, and flexible circuits. It is also mixed into paints and coatings to help prevent static and rust.
- Thermal Management
Graphene powder is added to materials that aid in heat transfer in electronics. Its high heat conductivity helps in cooling high temperatures in smartphones, LED lighting, CPUs, and power electronics.
- Water Filtration and Environmental Protection
Graphene powder is utilized in filters and membranes for purifying water and removing salt. It is highly effective in removing salt and heavy metals and organic waste. Its high surface area is effective in trapping impurities.
Advantages of Graphene Powder
- High Surface Area: Allows it to engage more with other materials.
