Our company aims to commercialize graphene particles smaller than a few microns as industrial products worldwide. After application, they adhere quite strongly upon drying, resulting in no gaps between the layers of graphene. To enhance the adsorption and desorption speed of ions from the electrolyte, as seen in electric double-layer capacitors, it is necessary to create gaps. To use them effectively, it is suggested to add a small amount of the conductive additive MCB currently used in lithium-ion batteries. **Features of our conductive graphene particles:** - Excellent conductivity, along with superior acid resistance, alkali resistance, heat resistance, and oxidation resistance. - Considered for use as a solid lubricant. - Produced through a very cost-effective method, making it suitable for general paint pigments. - Achieved a conductivity of 2×10^-3 Ωcm. - Prototypes have reached 10^-4 Ωcm. *For more details, please refer to the PDF document or feel free to contact us.*
