Natural Graphite flakes for Graphene production by electrochemical exfoliation

Large-scale graphene production has received significant attention because of its interesting properties and a wide range of potential applications. Conventional approaches provide scalable pathways for large scale production, however, these methods face several challenges such as usage of corrosive, toxic solution, long duration, and poor quality of graphene produced which severely affects its potential applications. This has also hindered graphene commercialization, resulting ‘high risk’ associated with its usage. However, the potential impact and market opportunities offered by this material are immense. Recently, electrochemical exfoliation approach for graphene has been proposed for a high production yield with better quality. Lab-scale studies show that electrochemical approach has the potential to unravel most of these challenges. Moreover, this approach provides high-quality graphene at low-cost. This could have huge impact on different sectors especially electronic & telecommunication, battery electrodes. The potential of this technology could be further enhanced with the usage of a cheaper raw material such as natural graphite flakes which is around 80% cheaper than currently used graphite foil.
