The difference in charge causes electrons to move through the wire towards the positive terminal of the battery, where they are removed from the wire. At the same time, the negative terminal supplies more electrons to the wire, so the charges don''t continually build up at the battery terminals.
That''s a challenging, diverse set of questions. 1. The electrons in the particular galvanic cell you mention join up with Cu ++ ions from the solution to make plain Cu atoms, which sit on the Cu electrode. 2. Electrons, like all small things, are indeed fuzzed-out waves, not located in one exact place.

The positive electrode, on the other hand, will attract negative ions (anions) toward itself. This electrode can accept electrons from those negative ions or other species in the solution and hence behaves as an oxidizing agent. In any electrochemical cell the anode is the electrode at which oxidation occurs. An easy way to remember which ...

When a lithium-ion battery is charging, lithium ions move from the cathode (positive electrode) to the anode (negative electrode) through the electrolyte. The anode, usually made of graphite, acts as a host for these lithium ions, which get stored in its layered structure. At the same time, electrons are forced to move through an external ...
On the other hand, the ions move from the cathode to the anode internally during charge in order to attract the electrons to move from the cathode back to the anode through the wires. However, I don''t understand what causes the ions to move to the cathode during discharge, and what causes them to move to the anode during charge.

In a current lithium-ion battery, the separator does not have any other functions apart from insulation and is totally submerged in the liquid electrolyte which soaks everything inside the cell and becomes a real medium through which lithium ions move between the cathode and anode, where the anode is made from a graphite structure. …
When the battery is being charged up, Li+ lithium ions leave the positive electrode (cathode) and are stored in the negative electrode (anode). When it is discharged to produce an electric current, the Li+ ions move in the opposite direction. These cells, each with a voltage of a few volts, can be grouped together in varying numbers, depending ...
An exotic state of matter — a "random solid solution" — affects how ions move through battery material. Diagram illustrates the process of charging or discharging the lithium iron phosphate (LFP) …
However, Kirchhoff''s circuit laws were derived for electron transport, not ion transport. Electrons only move when there''s an electric field, but ions can move without an electric field ...
By connecting a battery or other source of current to the two electrodes, we can force the reaction to proceed in its non-spontaneous, or reverse direction. ...

The solution separating the graphite and lithium cobalt oxide contains positively charged lithium ions, which easily form and break chemical bonds as the battery is discharged and recharged.
We call this a closed path because there''s a circle: current starts at the battery and ends at the battery. There''s confusion because the battery actually exists of two objects: the positive and the negative pole. Look at this circuit (which is basically the same, but with a capacitor instead of a battery and a resistor instead of a bulb):

For some electrodes, though not in this example, positive ions, instead of negative ions, complete the circuit by flowing away from the negative terminal. As shown in the figure, the direction of current flow is opposite to the direction of electron flow. The battery continues to discharge until one of the electrodes is used up [3, p. 226].
