Rechargeable batteries made from food
A team of researchers from the Italian Institute of Technology (IIT) has achieved an important advance in the world of technology. It has created the first rechargeable and edible battery made from food.
Speaking of technology and technological advances, it is recommended that you visit IceCasino. Here you will find a window to the future of online casinos with intuitive software, thousands of games, unmatched welcome bonuses, and the best live casino on the market.
But if you are here because you want to know all the details about this strange and important discovery about how batteries are made from organic material, we recommend that you read the article until the end.
Features of edible battery
Edible electronics apparently are here to stay. The interesting thing is that since it is a battery made of organic materials, they are ideal for replacing traditional batteries that can be very toxic. They are even really good for devices that must work inside the body, and would be better adapted to the internal environment of the human being.
What do these organic batteries use to work?
If you are here it is because you have some basic knowledge of how batteries work. TRUE?
A battery is an electrochemical device that stores and releases electrical energy. This is made up of at least two types of conductive materials called electrodes, which are made of conductive materials that have ions.
These electrodes are wrapped in an electrolyte, which is a substance that allows ions to move between the electrodes.
During this process, electrons flow from the negative electrode (anode) to the positive electrode (cathode). For all this, a circuit is needed, which generates electricity and powers said device.
Can you imagine the same idea but with an organic battery? Each of the components would be replaced with edible components that have the same functionality.
- They use riboflavin present in the malls as an anode
- Quercetin found in onions, capers and other vegetables as a cathode;
- Activated carbon as a conductor
- The anode and cathode separator are made of nori seaweed
- The electrodes are made of beeswax
- Battery contacts are designed from cellulose and gold
- All components are authorized and legal for human consumption. They don't cause any damage
- The battery is very modest, with a voltage of 0,65 volts and a range that is measured in minutes. Still, its perfect organic design makes it ideal for situations where traditional batteries are not recommended.
What are the future uses of batteries?
- Its potential uses could be to connect to organic circuits and measure, for example, the characteristics of certain foods.
- They could also be used on anything that is “children's toys” as there is a high risk of them putting the device in their mouth or swallowing it.
- Batteries with longer useful life will be developed and can be very useful in highly complex surgeries to reduce risks for patients.
What does science think of this achievement?
Researchers are realistic and consider that before this invention can be definitively introduced into the lives of human beings, years of improvement are needed.
They need a device that is not only reliable, but also useful, has significant durability, and, of course, replaces traditional batteries as this invention promises.
Furthermore, edible batteries are an exciting alternative for the energy storage industry in general.
All of this is explained by the fact that with the demand and increase in traditional batteries, building safer batteries without the use of toxic materials becomes a challenge but at the same time a necessity.
Potential future uses range from edible circuits, sensors that can monitor the conditions of our health, that is, what happens inside our body, to the quality of food with sensors to monitor the conditions of the food.
In the future, the responsible team. It is already designing models with greater capabilities in smaller sizes, with the hope of soon promoting soft, edible robots for use in medical procedures.
Can you imagine a robot that operates on you and that can be eaten?
Scientists also think that in the field of medicine they could be really useful and personalized batteries could be created for each human being and that are not toxic but organic. That is, everything we use that is “not human” is as natural as possible.
They can also serve as sensors that monitor our health and that we have to use them throughout our lives in cases of chronic diseases. The idea is that there is no device that “charges unnaturally.”
Although these batteries are still a long way from powering electric vehicles, they do show that it is possible to create batteries with safer materials than those currently used. Will lithium ion batteries disappear?
