An Italian research team has succeeded in producing edible batteries from foodstuffs. Batteries, developed by the fact that foods, which are a part of our meals or snacks in our daily lives, can store energy, are extremely remarkable. It is predicted that these batteries will play a major role in the technologies developed especially in the field of health.
Does not contain toxic substances
Edible batteries only use the energy storage capacity of food. Thus, unlike the lithium-ion batteries we use in daily life, it does not need heavy metals. This allows edible batteries to be used in sensitive sectors that interact with the body, such as ‘health’.
Scientific studies for batteries made from foodstuffs started in 2019. The activities in the intervening time finally bore fruit. In this way, the world’s first rechargeable renewable batteries were produced.
It is a fact that each of us knows that electrical energy is extremely important for technological inventions. Batteries are also indispensable for small technology units. Renewable batteries can provide electrical energy to the system they are included in the healthiest and safest way. We can say that these aspects will allow us to see them more often in the future.
The main uses of edible batteries in the first place are; There will be small examination devices to be used in the body, food analysis, and mini robots developed especially for the health field. In the future, it seems that it will have a much wider usage area.
The components of edible batteries are extremely familiar!
The main materials of renewable batteries are; almonds, capers, activated charcoal, seaweed, gold foil and water. The functions of these materials in the battery are as follows:
- Almond & Caper : These two materials form the anode-cathode couple required for the redox reaction to take place. The riboflavin vitamin in almonds acts as the anode, and the quercetin in capers acts as the canoe.
- Activated Charcoal: Activated charcoal, which is frequently encountered even in the cosmetics industry, is used to increase conductivity in edible batteries.
- Seaweed: Nori seaweed, which is the type of seaweed used in sushi, an indispensable member of the Far Eastern cuisine, prevents the short circuit in the battery.
- Gold Foil: Mostly used by chefs for presentation purposes, gold foil is used to provide external connection in edible batteries. This usage is within the same logic as gold in batteries.
