The battery is like a pump taking electrons from the carbon electrode and depositing them on the zinc electrode, but like a water pump which can only pump water to a finite height the same is true of the electron pump which can only move electrons across a finite potential difference. About 1.5 volts in the case of a carbon-zinc battery.

9.8: Batteries

Because galvanic cells can be self-contained and portable, they can be used as batteries and fuel cells. A battery (storage cell) is a galvanic cell (or a series of galvanic cells) that contains all the reactants needed to produce electricity. In contrast, a fuel cell is a galvanic cell that requires a constant external supply of one or more reactants to generate electricity.

The Positive and Negative of A Lithium Battery

What are Cathode and Anode for a lithium battery？ The negative electrode in a cell is called the anode. The positive side is called the cathode. During charging, the lithium ions move from the cathode, through the separator, to the anode. During discharge, the flow reverses. The most popular material used for the anode is graphite.

How to Define Anode and Cathode

Flow of Current . In the general sense, current refers to any movement of electrical charge. However, you should keep in mind the convention that current direction is according to where a positive charge would move, not a negative charge. So, if electrons do the actual moving in a cell, then current runs in the opposite direction. Why is it defined this way?
