Performance Study of Graphite Anode Slurry in Lithium-ion Flow Battery by Ball Milling

Graphite anode slurry of lithium-ion flow battery was prepared by the method of ball milling. The morphology, conductivity, specific capacity and cycle performance of graphite anode slurry were studied. Results show that the addition of conductive carbon material can improve the suspension stability...
