All materials at temperatures above absolute zero have some resistance to the flow or movement of electrons through the material, even the materials that compose the battery. All materials are swimming pools of electrons and nuclei that get in the way of the electrons traveling from one end of the battery to the other, and since the positive end of the battery is taking in electrons all the time, and the negitive end is pouring out electrons all the time, there must be electrons traveling in the battery from the positive end to the negative end, each one dodging the structural crowd of electrons and nuclei that make up the battery (the material of the battery).

The voltage in a battery is generated by a chemical process inside of it. Since the chemical process cannot generate an infinite current due physical limitations, if one tries to draw too much current from a battery, the voltage drops. This drop is modelled as the internal resistance.

What he said but also bear in mind that the chemicals
themselves are not perfect conductors.
therefore they are reisistors and have IE: internmal resistance....
internal resistance is the limiting factor in how much current a battery can give out.

when the current is drawn from a cell, chemical reaction takes place in side the electrolyte of the cell and the ions moves towards the electrodes inside the electrolyte. The electrolytes offers some opposition to the flow of ions through it which is referred to as the internal resistance of the cell. This provides a limiting factor to what maximum current can be drawn out of the cell.
