Conductive additive for Lithium-ion battery
We have been developing graphene dispersion that can be used as conductive additive for lithium-ion battery. Currently, carbon black or carbon nanotube are conventionally used as conductive additive. We can decrease electrode resistance and improve rate and cycle performance by using our graphene in combination with the carbon black or the carbon nanotube. We have confirmed that our graphene is effective in various cathode active materials such as NCM, NCA, LFP, LCO. Additionally, since our graphene dispersion using NMP solvent is high carbon concentration, it’s possible to increase non-volatile content in slurry mixing process.
