Introduction to Flow Batteries: Theory and Applications

A flow battery is a fully rechargeable electrical energy storage device where fluids containing the active materials are pumped through a cell, promoting reduction/oxidation on both sides of an ion-exchange membrane, resulting in an electrical potential.

Introduction to Flow Batteries: Theory and Applications

How do batteries work? A simple introduction

Primary batteries are ordinary, disposable ones that can''t normally be recharged; secondary batteries can be recharged, sometimes hundreds of times. You can recharge secondary batteries just by passing a current through them in the opposite direction to which it would normally flow (when it''s discharging); you can''t normally do this with

Current flow in batteries?

The easiest way to think of it is this: Current will only ever flow in a loop, even in very complex circuits you can always break it down into loops of current, if there is no path for current to return to its source, there will be no current flow. In your battery example, there is no return current path so no current will flow. There is
