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.

Nanowires are tiny wires, thousands of times thinner than a human hair. They are highly 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 at present they do not provide long battery life as they break over time. Most researchers agree that 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 ιστοσελίδα of the UCI.
"This research shows that nanowire batteries can have a long life and we can make it a reality."
Depending on the capacity of the battery, 100.000 recharging cycles could mean years, if not a lifetime. This technology is not limited to pocket-sized batteries for your children's toys, but also for smartphones, laptops, and why not, for electric cars.
