Conductive carbon black is an important additive for lithium ion battery cathode electrode.
Its role is to improve the electron transfer between the positive electroactive material coating and the collector, reduce the contact resistance of the electrode interface, and play the role of depolarization.
Lithium-ion battery pole piece is prepared by water-based adhesive, which not only can solve the environmental pollution and protect the health of operators, but also is a green, energy-saving and emission reduction battery production technology.
Conductive carbon black is better than oleophilic carbon materials, battery pole piece prepared by water-based adhesive, conductive carbon in the pulp dispersion is poor, easy to form agglomerated particles. In order to solve the dispersion of conductive carbon black in water-based slurry, this work uses hydrogen peroxide to oxidize conductive carbon black to improve the hydrophilicity of conductive pigment carbon black.
As a result, the water peroxide-treated conductive pigment carbon black in the electrode material binder system significantly reduced the rate of change of internal resistance during battery cycling and improved the cycle life of the battery.
Under the charging and discharging cycle conditions, the cycle life of the battery was increased by 47.1%. The effect of surface-modified conductive carbon in improving the battery cycle life is due to the improved interfacial bonding state between the conductive carbon black and the cathode material.
Conductive carbon black is an important additive for lithium-ion battery cathode wafers, and its role is to improve the electron transfer between the cathode active material coating and the collector, reduce the contact resistance of the electrode interface, and play the role of depolarization.
