Carbon nanotubes (CNTs) have a wide range of potential applications due to their unique mechanical, electrical, thermal, and chemical properties. They are primarily used as conductive additives in lithium-ion batteries, but their applications extend to composites, electronics, and green technologies. CNTs enhance the performance of materials like conductive polymers, fiber-reinforced composites, concrete, and metal composites. They are also used in transparent conductive films, thermal interface materials, and sensors. Emerging production methods, such as using green or waste feedstocks, further expand their potential in sustainable applications. Additionally, CNTs play a critical role in nanoelectronics and field emission devices, making them integral to advanced technologies.
