Flow batteries allow for independent scaleup of power and capacity specifications since the chemical species are stored outside the cell. The power each cell generates depends on the current density and voltage. Flow batteries have typically been operated at about 50 mA/cm 2, approximately the same as batteries without convection. [3] However ...
A flow chart, also known as a flowchart, is a type of diagram, made of boxes and arrows.It can be used to show: An algorithm, a step-by-step list of directions that need to be followed to solve a problem; A process, a series of stages in time where the last stage is the product, result or goal.; The planned stages of a project.; The flow chart uses boxes, arrows and other elements:
Voltaic Cells. An electrochemical cell which causes external electric current flow can be created using any two different metals since metals differ in their tendency to lose electrons. Zinc more readily loses electrons than copper, so placing zinc and copper metal in solutions of their salts can cause electrons to flow through an external wire which leads from the zinc to the copper.

Zinc-plated or galvanized iron uses a different strategy. Zinc is more easily oxidized than iron because zinc has a lower reduction potential. Since zinc has a lower reduction potential, it is a more active metal. Thus, even if the zinc coating is scratched, the zinc will still oxidize before the iron.
