Several civilizations, including the Egyptians and Romans, worshiped the egg as a symbol of fertility and perfection. But the application doesn’t stop there. This time, scientists are tapping into the potential of calcium carbonate, which is found in large amounts in eggshells.Its use can provide enough A breakthrough in the technology behind today’s batteriesThe team of researchers involved in this project is headed by scientists from the Helmholtz Institute Ulm. in Germana research center focused on Development of new battery technology.
Together with Australian researchers, German scientists studied the electrochemical properties of these shells.Within this technical project they have explored the possibilities offered by eggshell The egg membrane is ground into a thin powder. The powder was heated at 300° C. for 2 hours to obtain calcite. It was then used as an electrode in a non-aqueous electrolyte, a metallic lithium anode immersed in a solution that acts as an electrical conductor. The results showed a high power saving efficiency of 92% after 1000 charge/discharge cycles. The next step is the creation of low-cost lithium-ion capacitors containing newly discovered materials.
According to the researchers, this is the first time organic waste has been used as an electrode, although there is still a long way to go. This can be seen as a new approach to zero waste. circular economy We aim for a more sustainable society.
Endless Applications of Eggshells
However, this humble natural casing has far more uses. With an estimated 1 billion tonnes of eggshells produced each year in Europe, efforts to recycle eggshells are good news. Eggshells are now used for several purposes. One of the most impressive is the biodiesel production, This reduces the use of polluting compounds. It can also be used to create bone structures for patients suffering from osteoporosis. Likewise, their fertile and nutritional properties make them excellent candidates for supplements used in plants, animals, and humans. One of the ingredients.
And if that’s not enough, it’s also a great ally for all sorts of home hacks.From facial masks to cleaning products with abrasive properties to garden fertilizers and makeshift nurseries, eggshell It can also be used as a mini flowerpot for first buds.
