Graphene Dispersion in NMP (Oxygen Reduced)
This product is thin graphene based NMP dispersion with high electrical conductivity. It is non-toxic‚ non-strang odor‚ non-corrosive characteristics‚ chemical stability‚ and low resistivity. By contrast with the similar products‚ this product with technical advantages is metal ion free and can be widely applied in battery slurry as conductive agent to improve the high rate charge-discharge capacity.
