An Electrical battery has electrodes or terminals on its two ends. One is called the cathode (negative) and the other is called the anode (positive). In between the two terminals there is an electrolyte (usually a liquid). The electrolyte is an ionic solution. The positive (cations) and (anions) negative ions in the electrode travel towards the opposite terminals. The force driving them is called the electromotive force EMF. EMF is actually the potential difference between the two terminals.
An electric field is E created due to the potential difference between the two terminals. There is a force F acting on the ions of charges q due to E, as per F = E q. Electrostatic forces act inside the battery. But the net force acting on it will be zero.
