Application Fields
This product is a thin graphene-based NMP dispersion with high electrical conductivity. It’s nontoxic‚ noncorrosive, chemically stable, and demonstrates low resistivity. In contrast with other similar products‚ this graphene dispersion in NMP (oxygen reduced) is metal-ion free and can be widely applied in battery slurries as a conductive agent to improve the high rate charge-discharge capacity. It’s also effective in various types of battery electrode materials and conductive additives‚ such as lithium-ion battery‚ nickel hydrogen battery‚ alkaline (manganese dioxide) battery cathode, or anode material conductive agents.
