how does a battery provide a potential difference for charge to flow?

In battery potential difference is created due to chemical reaction. Due to chemical reaction between the electrode and the electrolyte, one electrode becomes rich in electron i.e. gains -ve polarity, on the other side another becomes +ve polarity. So a potential difference is created which enables charge to flow in the external circuitry.
