How Does Electricity Flow? In order to understand how electricity flows, we need to start with the basics. Electricity is the flow of electric charge, which, in most household contexts, means the movement of electrons through a conductor. These electrons move from areas of negative charge to areas of positive charge, creating an electric current.
storage capacity enables a flow battery system to reduce its levelized cost per kilowatt-hour delivered over the course of its lifetime, something that Li-ion battery systems are not able to do. Flow battery systems also require little to no thermal management and therefore do not present the same fire risk as Li-ion or molten salt batteries.
