Scalable Preparation and Application of Light-to-Moderately Oxidized Graphene

With the rapid development of artificial intelligence (AI) computing power and the new energy industry, the demand for high-performance graphene materials continues to grow, and precise control of the oxidation degree together with batch-to-batch consistency is critical to their downstream applications. This report presents the progress of CASYUEDA in the scalable preparation and application of light-to-moderately oxidized graphene. Based on an in-house developed process route and equipment optimization, the oxidation degree can be tuned and stably produced within a range of about 5% to 25%, forming a product series that covers different application requirements. The low-oxidation-degree product is mainly oriented to battery systems and has been validated by downstream battery manufacturers, while the high-oxidation-degree product can be used to prepare self-supporting conductive films that require no reduction, showing potential in flexible electronics and thermal management. The company also advances the digitalization and intelligentization of its R&D process by introducing AI-assisted real-time particle-size analysis and batch quality control, so as to improve product consistency and responsiveness. These advances provide a viable path for the scalable application of graphene materials in new energy and related fields.

Biography

Prof. Guqiao Ding is a researcher and doctoral supervisor of SIMIT, Chinese Academy of Sciences (CAS). He started researching graphene since 2009, applied first graphene patent in 2010. Dr. Ding is actively involved in material research in exploring innovative preparation, batch preparation, and application of graphene materials, especially powders and slurries. He has been authorized over 50 patents, and published over 200 SCI papers with citation over 10,000 times in journals including Adv. Material, Adv. Funct. Mater., Chem. Mater., Carbon and so on.

Dr. Ding took on the industrialization technology development of graphene powder since 2015. He established Zhongke Yueda (Shanghai) Material Technology Co., Ltd. in 2018, together with SIMIT and Yueda Group. Dr. Ding successfully led the team conquering the technology chain of natural graphite, graphene oxide, graphene thermal conductive film, and overcoming the gap from laboratory technology, pilot process to mass production and application. At present, Dr. Ding with his research team now attempt to conquer the batch preparation of graphene materials with high single-layer ratio, high lattice quality, and controllable lateral size, which will promote the downstream application development of graphene.
