New Nanowire based batteries can go a lifetime

26 Feb 2019

Scientists of the University of California have come up with a nanowire based battery substance that will make charging batteries as easy as ever. In fact the scientists believe that this nanowire based charging system, might just allow you to never change your battery again. According to the reports, when any battery is charged using the nanowire tech, it automatically amplifies the life of the commercial batteries that we use daily. They believe that the technology has great applications in smartphones, computers, electrical appliances and even spacecrafts.

In the past, the researchers from the university had success in maintaining 97% battery after approximately 1000 cycles of charging and discharging. This was attained using silicon nano particles inside the lithium ion batteries. The design greatly improved the capacitive power of the batteries. The nanowires used in this technology have extremely high conductivity along with surface area. The only issue that is still lingers is the lack of tensile strength for the thin filaments. Their fragile natures might just lead to a circuit break every time more pressure falls in.

The issue has been solved by the use of gold nanowire coated with manganese dioxide. This led to the nanowires having the strength to conduct infinite loops of power. The solution was brought up by Mya Le Thai, who did the testing of the electrode at up to 200,000 cycles in a time period of just 3 months.

Reginald Penner, senior author and chair of University of California Irvine’s Department of Chemistry said, “Mya was playing around, and she coated this whole thing with a very thin gel layer and started to cycle it. She discovered that just by using this gel, she could cycle it hundreds of thousands of times without losing any capacity.”

In general, normal batteries break after just 7000 cycles of charging and discharging. The idea is that the metal oxide is helping the nanowire to retain its tensile strength. Some people believe that nanowire is going to be the next big thing in electronics. In fact scaling up electronic devices will also be easy once nanowires venture it. The whole study in this regard is published in the American Chemical Society’s Energy Letters.
