In the real world, though, the actual amount of charge that gets separated in a battery is very small. The chemical reaction in a battery can only happen when there's a complete circuit; the chemicals at one electrode can then dump electrons into the circuit, while at the other electrode they take electrons away.
It is said that the battery does not have a charge separation on its electrodes and only the chemical reaction generates voltage. But in the comment, it is said again that there's charge separation on the electrodes thus producing the electric field and voltage.
A separator is a permeable membrane placed between a battery's anode and cathode. The main function of a separator is to keep the two electrodes apart to prevent electrical short circuits while also allowing the transport of ionic charge carriers that are needed to close the circuit during the passage of current in an electrochemical cell.
Similarly, for batteries to work, electricity must be converted into a chemical potential form before it can be readily stored. Batteries consist of two electrical terminals called the cathode and the anode, separated by a chemical material called an electrolyte. To accept and release energy, a battery is coupled to an external circuit.
Ions are atoms that have lost or gained electrons and have become electrically charged. Although ions pass freely between the electrodes, the separator is an isolator with no electrical conductivity. The small amount of current that may pass through the separator is self-discharge and this is present in all batteries to varying degrees.
Scientists study processes in rechargeable batteries because they do not completely reverse as the battery is charged and discharged. Over time, the lack of a complete reversal can change the chemistry and structure of battery materials, which can reduce battery performance and safety.
In redesigning the battery I believe that movable battery components and the use of a new form of cellulose would solve the persistent problems plaguing lithium batteries. …

A watch battery, coin or button cell (Figure (PageIndex{7})) is a small single cell battery shaped as a squat cylinder typically 5 to 25 mm (0.197 to 0.984 in) in diameter and 1 to 6 mm (0.039 to 0.236 in) high — like a button …
When the battery is discharged, the chemical reaction is reversed, and electrons flow from the cathode back to the anode. Overcharging. One of the primary reasons why …
The final part of the battery, the separator, is fairly straightforward. The separator''s role is to keep the anode and the cathode separated from each other inside the battery.
Separators are electrochemically inactive thin porous membranes that physically separate the cathode from the anode, while allowing ion transport to occur. Separator shutdown above the melting point seeks to …

From the mid 18th century on, before there were batteries, experimenters used Leyden jars to store electrical charge. As an early form of capacitor, Leyden jars, unlike electrochemical cells, stored their charge physically and would release it all at once. Many experimenters took to hooking several Leyden jars together to create a stronger charge and one of them, the colonial American inventor Benjamin Franklin
