As human beings, we spent almost most of our time using our smartphones. However, spending too much time on a smartphone would result in a heating device. Some people do intensive gaming, which results in overheating. Many companies use liquid cooling systems and cooling fans to control the temperature of the battery. But what if I told you that there is a gel that can turn the heat of the battery in electricity to charge up your device? Don’t believe me? Let me explain.
A group of scientists has created a special gel that can take out the heat of the battery and turn it into electricity, hence, cooling down the battery. They have named it as thermogalvanic gel. As of right now, it operates on a tiny scale, but with future improvements, the gel could become highly useful.
Now let me tell you how the gel works! The gel is infused with water and some precise ions, and when the heat passes through this thermogalvanic gel, two of the ions transfer electrons between the electrodes to generate electricity. After this, the infused water in the hydrogel absorbs the heat and evaporates, resulting in cooling the battery. The scientists say that when all the water in the gel is dissipated, it can recharge itself by absorbing the water back from the air around it.
To test it out, the scientists took a 2mm film of the thermogalvanic gel to use it on a fast-charging battery of a smartphone. They were able to decrease the temperature of the battery by 20-degrees while producing a mere power of 5 microwatts (0.000005W).
This technology has a huge potential in itself. In the coming future, this gel could be the one to change the cooling system game in the smartphone industry. However, we would have to wait for some time to get the technology to be stable and fully complete.
