In summary: You are proposing to create a dangerous reaction in a fume hood and without any safety equipment. Do not proceed.

TL;DR Summary: Dry cells are usually not rechargeable but I had a few ideas.

Basically dry cells are not rechargeable as zinc reacts with ammonia to form complex compounds which can't be revived. Consequently the quantity of reactants reduce thus hindering it from recharging.
So in a dry cell, Zinc and Manganese oxide/graphite are taken as electrodes. What if we took Zinc and Zinc oxide as electrodes? They could be kept in an acidic medium, and as both are of same degree of reactivity, could the cell now be recharged?

What would be the point? You are essentially proposing a new kind of battery chemistry - why do you think this has been overlooked by what is a multi-billion dollar business?

I have to make an investigatory project and thought of constructing a cell which is rechargeable is all. So the only thing that matters to me is if it works or not

So what do you need from us? If you need to do the experiment for school, you should do the experiment.

"Works?" Or works for how many/few charging cycles? Deep cycles? High current?

In a fume hood, while wearing safety glasses and a thick apron, with a fire extinguisher and safety shower nearby...

They all work very well. Each has its particular weakness. It would be important for any newcomer to outperform the existing technoloogy. By what margin does the proposed @chemisttree battery accomplish this? This is a theory question for the OP.

No, dry cells cannot be made rechargeable.

Can a dry cell be made rechargeable?

Technically, it is possible to convert a dry cell into a rechargeable cell, but it is not practical or safe. Dry cells are designed for single use, and modifying them for recharging can lead to leakage, overheating, or even explosions.

What are the challenges in making a dry cell rechargeable?

The main challenges include the chemical composition of the dry cell, which is not designed to handle repeated charge and discharge cycles. Additionally, the physical structure of the cell may degrade, leading to safety hazards and reduced efficiency.

Are there any commercially available rechargeable dry cells?

No, there are no commercially available rechargeable dry cells. Instead, rechargeable batteries such as nickel-cadmium (NiCd), nickel-metal hydride (NiMH), and lithium-ion (Li-ion) batteries are used, which are specifically designed for repeated charging and discharging.

What happens if you try to recharge a dry cell?

Attempting to recharge a dry cell can cause the electrolyte to break down, leading to gas build-up, leakage, and potential rupture of the cell. This can result in damage to the device it is powering and pose safety risks to the user.

Why are dry cells not designed to be rechargeable?

Dry cells are designed for convenience, low cost, and single-use applications. The materials and construction methods used in dry cells are optimized for one-time use, making them unsuitable for the repeated chemical reactions required in rechargeable batteries.
