The remarkable properties of graphene and related materials (GRMs) promise substantial benefits for a wide range of technologies. Their industrial utilization, however, critically depends on the availability of suitable GRM supply in terms of both quality and quantity at a competitive price. All factors remain highly specific to the each application scenario, while the emerging GRM supply industry still struggles to engage prospective clients in active development of GRM-enhanced products. The present issue of Graphene Roadmap Briefs compiles results on the status and prospects of GRM industrialization gathered by several innovation interface investigations (3I) that we conducted throughout the past 3 years. Each 3I study focussed a unique prospective value chain that GRM innovation promises to enable or advance in the future. While individual roadmaps mainly cover the peculiarities of the specific GRM supply chain under investigation, we combine all results regarding the primary material supply sector and it is rapidly evolving innovation context in Europe and beyond here. We introduce both the initial 2018 graphene industrialization roadmap and its thorough 2020 revision and extension. Our conclusions cover both crucial factors hampering the diffusion GRM today and opportunities to overcome these bottlenecks in the future. About: Graphene Roadmap Briefs Graphene Roadmap Briefs highlight key innovation areas impacted by graphene and related 2D materials (GRMs) as well as overarching aspects of GRM innovation status and prospects. The series bases on the evolving technology and innovation roadmap process initiated by the European Graphene Flagship. It covers crucial innovation trends beyond fundamental scientific discovery and applied research on GRM utilization opportunities.

Non-olivine LiCoPO 4 microcrystals have been synthesized at low temperatures by microwave-assisted hydrothermal synthesis. The resulting octahedra-like micrometer-sized crystals exhibit a Pn2 1 a symmetry and are isostructural to LiZnPO 4 . The orthorhombic lattice constants are a ¼ 10.023(8) Å, b ¼ 6.724(7) Å, and c ¼ 4.963(4) Å. The microcrystals are metastable and transform to olivine LiCoPO 4 upon heating above T z 220 C under an argon atmosphere. The magnetic properties confirm a phase pure material with a Co-valence of 2+, and imply long-range antiferromagnetic ordering below T N ¼ 11 K. Electrochemical analysis by means of cyclic voltammetry displays a reversible redox couple at around 5.1 V/4.8 V vs.

Microwave-assisted hydrothermal synthesis was used to grow LiMnPO 4 micro-and nanocrystals from acetate precursors. By appropriate adjustment of the precursor concentration and the pH-value of the reactant, the product composition and purity along with the crystal size can be manipulated, resulting in particle-dimensions from around 10 µm down to a few 100 nm. Prisms and plates with hexagonal basal face as well as cuboid and rod-like particles were produced. The effects on the crystal morphology as well as on the materials texture and agglomeration tendency are discussed and a comprehensive agglomeration phase diagram is constructed.
