A battery is another device for storing charge (or, put another way, for storing electrical energy). A battery consists of two electrodes, the anode (negative) and cathode (positive. Usually these are two dissimilar metals such as copper and zinc. however, when analyzing circuits the direction of the current is taken to be the direction of

Positive charges are normally stuck in place in solids and cannot move freely. However, because a positive current moving to the right is the same as a negative current of equal magnitude moving to the left, as shown in Figure 19.4, we define conventional current to flow in the direction that a positive charge would flow if it could move. Thus

The direction electrons flow is, in terms of circuitry, irrelevant. Voltage is actually relative, and does not exist without two terminals. For instance, if you have the negative terminal grounded (at zero volts) and the positive terminal is "live", then you can think of it as the positive terminal sucking electrons from the grounded terminal.

Confusion about the current direction in batteries arises from the historical convention and the nature of electrical flow. In conventional terms, current flows from the positive terminal to the negative terminal, while electron flow actually moves in the opposite direction, from negative to positive.
Current flows from the positive terminal to the negative terminal in a battery. In electrical terms, this is known as conventional current flow. This flow is defined by the movement of positive charge. Electrons, which carry a negative charge, actually move in the opposite direction, from the negative terminal to the positive terminal.
The common misconceptions about battery flow directions primarily involve the movement of current and electrons. Many people mistakenly believe that current flows from the positive to the negative terminal, but this is not entirely accurate. Current flows from positive to negative. Electrons flow from negative to positive.
It was discovered that if a battery, with its positive side connected to the added electrode (plate), and its negative side connected to the filament (cathode), an electrical current would flow. If the battery was connected the other way around, it was also observed that no current would flow.
This apparent contradiction arises from historical conventions in electrical engineering, which defined current flow based on the movement of positive charges. In reality, the internal chemical reactions within the battery generate an excess of electrons at the negative terminal.
