  Efficient and scalable production of two-dimensional (2D) materials is
required to overcome technological hurdles towards the creation of a
2D-materials-based industry. Here, we present a novel approach developed for
the exfoliation of layered crystals, i.e., graphite, hexagonal boron nitride
and transition metal dichalcogenides. The process is based on high-pressure
wet-jet-milling (WJM), resulting in 2 L/hr production of 10 g/L of single- and
few-layer 2D crystal flakes in dispersion making the scaling-up more
affordable. The WJM process enables the production of defect-free and
high-quality 2D-crystal dispersions on a large scale, opening the way for the
full exploitation in different commercial applications, e.g., anodes active
material in lithium ion batteries, reinforcement in polymer-graphene
composites, and transparent conductors as we demonstrate in this report.
