Mass production and commercial availability are prerequisites for the viability and wide application of graphene. Exfoliation of graphite to give graphene is one of the most promising ways to achieve large-scale production at extremely low cost. This review focuses on discussing different exfoliation techniques based on a common mechanical mechanism; as a deep understanding of the exfoliation mechanism can provide useful information on how to efficiently obtain high-quality graphene by optimizing exfoliation techniques. We highlight recent advances in mechanical exfoliation for graphene production over the past decade. The focus is on the widely used sonication method with the latest information on sonication-induced defects, the newly explored ball milling method, the fluid dynamics method that has emerged in the last three years, and the innovative supercritical fluid method. We also provide insight into how to efficiently obtain high-quality graphene using mechanical exfoliation techniques. We hope that this review will point to a rational direction for scalable graphene production.
