Marubeni Corporation, (hereinafter, “Marubeni ”), Marubeni Tetsugen Co., Ltd, (hereinafter, “Marubeni Tetsugen”), and NiSiNa materials Co. Ltd. (hereinafter, “Nishina materials”) have entered into a Strategic Partnership Agreement today, with the aim of developing new applications and opening up demand for graphene, a nano-carbon material(* 1) manufactured via a new method developed by Nishina materials.

Graphene is a monolayer of graphite (with a thickness of 1 nanometer) stripped off and has a molecular structure in which a large number of carbon atoms are bonded in a honeycomb shape on a plane. It is a nano-carbon material with high strength, electrical conductivity, thermal conductivity, and low friction, and because of these characteristics, it is expected to be applied in a wide range of fields such as electrodes, catalysts, heat dissipation materials, and lubricants. Graphene is generally manufactured by mechanical peeling or using an oxidant, but Nishina materials's proprietary method does not use oxidants, and instead focuses on superior mechanical peeling technology. For this reason, this new process is very safe with a low environmental load. In the future, we aim to improve production efficiency and reduce manufacturing costs through mass production, something that has historically been an issue for graphene production.

Marubeni and Marubeni Tetsugen, together with Nishina materials, will contribute to the spread of graphene by promoting the development of new applications and demand for graphene by utilizing Marubeni’s and Marubeni Tetsugen’s global business network.

(*1) nano-carbon material: An allotrope of nanometer-sized carbon such as graphene and carbon nanotubes, fullerenes.
