How a Battery Works: Anode, Cathode & Electrolyte Explained

In summary, the function of the electrolyte in a battery is to facilitate the chemical reaction between the anode and cathode. While conductors can also facilitate the flow of electricity, they cannot support the necessary chemical reaction for a battery to function. The stacking of a penny and nickel battery with electrolyte (wet cardboard) between them allows for the necessary chemical reaction to occur. However, there may not be electrolyte between the penny and nickel because it is not necessary for the reaction to occur at that point. It is unclear if the battery would work without any electrolyte between the pennies and nickels, as the chemical reaction may not occur properly without it.

So I understand that a battery consists of an anode, cathode, and electrolyte.

Question: What is the function of the electrolyte? Can we use a conductor instead of an electrolyte like some kind of metal? If so, why don't we?

Now for a penny and nickel battery stacked on top of each other you have a
penny, electrolyte (wet cardboard), nickel, penny, electrolyte, nickel, etc.
I have three questions:
1) Why is there no electrolyte between nickel and penny? (Look in the middle and you'll see what I mean)
2) Will it work if there was an electrolyte there?
3) Will it work without any electrolytes between any of the pennies and nickels?

Thank you for responding.

I didn't realize it has to do with the chemical reaction.
 

FAQ: How a Battery Works: Anode, Cathode & Electrolyte Explained

1. What is the purpose of an anode in a battery?

The anode is the negatively charged electrode in a battery. Its main purpose is to release electrons during the chemical reaction that produces electricity.

2. How does a cathode work in a battery?

The cathode is the positively charged electrode in a battery. It is responsible for accepting the electrons released by the anode and using them to create a potential difference, which results in the flow of electricity.

3. What is the role of the electrolyte in a battery?

The electrolyte is the substance that allows for the movement of ions between the anode and cathode. It is usually a liquid or gel that contains charged particles, which facilitate the chemical reactions necessary for the battery to produce electricity.

4. How does a battery store energy?

When a battery is fully charged, the anode and cathode have a large potential difference, and the electrolyte is able to facilitate the flow of electrons between them. This potential difference is what allows the battery to store energy until it is needed.

5. What are the different types of batteries and how do they differ in their operation?

There are various types of batteries, including alkaline, lithium-ion, lead-acid, and nickel-cadmium. They differ in their chemical composition and construction, which affects their capacity, voltage, and lifespan. Some batteries are rechargeable, while others are single-use. Each type has its own advantages and disadvantages, making them suitable for different applications.
