Carbon nanotubes are promising to revolutionize several fields in material science and are suggested to open the way into nanotechnology. These circular rod-shaped carbon nanostructures have novel characteristics that lead them to being potentially beneficial in many applications in nanoscience and nanotechnology. Their precise surface place, stiffness, power, and resilience have brought about lots of exhilaration in various areas. Nanotubes are categorized as single-walled nanotubes, double-walled nanotubes, and multi-walled nanotube. Various techniques have been evolved to produce nanotubes in bulk, including of arc discharge, laser ablation, chemical vapor deposition, electrolysis, and ball milling. Since their first observation nearly 20 years ago by Iijima, carbon nanotubes have been the focus of considerable research. Numerous researchers have reported remarkable physical and chemical properties for this new form of advanced carbon nanomaterials. Carbon nanotubes offer tremendous opportunities for the development of new material systems. This paper provides a concise report on recent advances in carbon nanotubes and their potential applications.

Carbon nanofibers are promising to revolutionize several fields in material science and are suggested to open the way into nanotechnology. Carbon fiber has become an important reinforcement material in composite materials and battery technology because of its low density, high strength, and tensile modulus. Furthermore, high electrical conductivity, thermal conductivity, and mechanical properties of carbon fiber make it useful in a wide variety of products. This chapter highlighting the synthesis and growth pattern of vapor grown carbon fiber (VGCFs). This chapter work reported here includes the application of VGCFs in composite and battery technology.
