Our company aims to commercialize graphene microparticles of less than a few microns as industrial products globally. After application, they adhere quite firmly upon drying, resulting in no gaps between the multilayer graphene. To increase the rate of ion adsorption and desorption of the electrolyte, as seen in electric double-layer capacitors, it is necessary to provide gaps. To use them effectively, it is presumed that adding a small amount of the conductive additive MCB currently used in lithium-ion batteries would be beneficial. **Features of our conductive graphene microparticles:** - Excellent conductivity, along with superior acid resistance, alkali resistance, heat resistance, and oxidation resistance. - Considered for use as a solid lubricant. - The manufacturing method is very cost-effective, allowing for expansion into general paint pigments. - Achieves a conductivity of 2×10^-3 Ωcm. - Prototypes have reached 10^-4 Ωcm. *For more details, please refer to the PDF materials or feel free to contact us.*
