Inside the lemon, the electrolyte solution reacts with the zinc electrode, freeing electrons that pass through the solution to the copper electrode.
There, the free electrons combine with hydrogen atoms, producing bubbles of hydrogen gas. This process can produce a weak voltage if the two electrodes are connected in a circuit.
Over time, the chemical reaction degrades the zinc electrode and depletes the electrolyte, rendering the battery useless. The amount of electricity generated by a lemon battery may vary depending on the individual characteristics of the fruit. In addition, the makeup of the nail and penny can alter the characteristics of the battery, as many of these items are made with alloys instead of pure metal.
In most cases, a single lemon cell provide slightly less than a volt of power. However, lemons may be connected in series to provide a higher voltage, suitable for illuminating LEDs or driving simple low-powered demonstration devices. How Does a Lemon Battery Work? Quick Answer A lemon battery uses the juice inside the lemon as an electrolyte to facilitate electrons moving between a pair of electrodes inserted into the fruit.
How Do You Build Batteries? How Do Photovoltaic Cells Work? Full Answer Inside the lemon, the electrolyte solution reacts with the zinc electrode, freeing electrons that pass through the solution to the copper electrode.
Generate Electricity with a Lemon Battery. A tingly science project from Science Buddies.
Lemon battery A lemon battery is a battery used in experiments proposed in many science textbooks around the world. It is made by inserting two different metallicobjects, for example a galvanized nail and a copper coin, into an ion bridge (for example a lemon, a potato or paper soaked in salt water or acid)/5(1).
A lemon battery is a simple battery often made for the purpose of education. Typically, a piece of zinc metal (such as a galvanized nail) and a piece of copper (such as a penny) are inserted into a lemon and connected by wires. Read this essay on Lemon Battery.

A lemon battery uses the juice inside the lemon as an electrolyte to facilitate electrons moving between a pair of electrodes inserted into the fruit. These need to be two dissimilar metals, such as a copper penny and zinc-coated nail. Completing the circuit creates a weak electrical current. Inside. The goal of making a lemon battery is turning chemical energy into electrical energy, creating enough electricity to power a small LED light or a watch.
