Your mobile of the future will be made with your leftover fish

It sounds like science fiction. But yes. Your mobile of the future will be made of fish remains . Or at least a part of it. Scientists from the University of Córdoba (Spain), the Wentworth Technological Institute (United States) and the University of Xiamen (China) have managed to take advantage of the viscera , head , scales and fin of tilapia , a lean fish of white meat usually raised in fish farms. Specifically, they have extracted the collagen stored in these parts and used it in energy storage systems. As is the case with batteries.

Fish waste is rich in nitrogen, oxygen, carbon or hydrogen

Fish waste is rich in nitrogen, oxygen, carbon or hydrogen, useful elements in batteries due to its electronegativity, stable nature and thermal stability. In this way, as explained by the Spanish project manager, Gregorio Ortiz,collagen is being used as an anode (negative pole) to combine it with cathodes (positive pole), thus analyzing its potential.

This advance could address the supply problem that exists with regard to lithium , the main competitor of batteries for portable devices. This alkali metal is extracted mainly from salt flats located in Chile, Argentina and Bolivia. For this reason, today, sodium and magnesium are also used for this same purpose. In fact, there are those who consider them the perfect alternative to replace this element that, at the same time, stands out for its contaminating potential .

During the investigation, these three elements have been experimented with, with positive results. According to the conclusions, the capacity values ​​achieved in the three cases are very similar, and even higher in some ranges, than those obtained with other chemically synthesized materials, with the advantage that, on this occasion, the battery’s anode It comes from a sustainable material that often turns into millions of tons of waste
