A team of scientists from the University of California, Irvine (UCI), accidentally discovered a method of generating batteries using nanowires that can last over 100.000 charging cycles without spoiling or losing performance.
Η search μπαταριών μακράς διάρκειας είναι αντικείμενο εργασιών πολλών επιστημονικών εργαστηρίων σε όλο τον κόσμο. Έτσι ενώ η συμβατική τεχνολογία μπαταριών έχει ήδη φτάσει στο αποκορύφωμά της, οι ερευνητές αναζητούν better results using nanowires as the main structure of tomorrow's batteries.
Nano wires are tiny wires, thousands of times thinner than a human hair. They are extremely conductive, and because they can be grouped in large numbers in small areas, they offer a very large surface for electron transport and energy storage.
The problem with nanowires is that they are extremely fragile, and currently do not provide long life in batteries, as they break over time. Most researchers agree that the technology has not been explored enough and that there is room for improvement.
Scientists from Irvine, California, accidentally discovered impressive results with nanowires that had invested with a gold coat in a manganese dioxide shell. Subsequently, submerging the entire setup in Plexiglas gel created reliable batteries that can be recharged over 100.000 times without losing any storage capacity or spoiling from much use. In previous experiments with nano-battery batteries, scientists were able to use the batteries for 5.000 recharge cycles.
Mya Le Thai PhD candidate from California, Irvine (UCI) who discovered tomorrow's battery, along with her colleagues, published the her findings yesterday. The team replaced the electrolyte fluid with a gel.
"Το επικαλυμμένο ηλεκτρόδιο διατηρεί το σχήμα του πολύ καλύτερα, καθιστώντας το μια πολύ πιο αξιόπιστη επιλογή," δηλώνει η Thai στην by clicking here of the UCI.
"Αυτή η έρευνα αποδεικνύει ότι οι μπαταρίες με νανοσύρματα μπορούν να έχουν μεγάλη διάρκεια ζωής και μπορούμε να το κάνουμε πραγματικότητα."
Depending on the battery capacity, 100.000 recharge cycles could mean years, if not the entire lifetime of a human being. This technology is not only limited to children's pocket sized batteries, but also for smartphones, laptops, and why not, for electric cars.
