How batteries work

Hi
Why the negative ion: OH- goes from the positive electrode to the negative electrode
in the process of using the Alkaline battery ?
thanks

Electric field.

So does that make Wrigley Field a battery since 1988, when they installed the lights?

Thanks for your answer.
But ion: OH- is negatively charged
and so is the negative electrode;
so they should repel each other.
thank you very much
