Researchers at the University of California at Irvine say they have created a never-ending battery. When they are used in a regular lithium-ion battery they expand, grow brittle and crack.

It may be this team’s new “nanowire”, which is “a gold nanowire in a manganese dioxide shell and encasing the assembly in an electrolyte made of a Plexiglas-like gel”. Researchers at the University of California in Irvine have found out a way of getting rid of this problem by accidentally building a new battery out of nanowires that can outlast 2,00,000 recharge cycles without any degradation.
Lithium-based batteries are also a growing issue for manufacturers as not only do they degrade in their ability to sustain energy after a number of charging cycles, but the lithium within it is highly corrosive when coming into contact with oxygen, both in the air and water.
Until we see the unbreakable batteries replace lithium-ion ones, batteries will continue to fail, the researchers claimed.
The quest for a long-lasting battery has given pressing headaches to scientists in laboratories around the world. He said that Mya discovered that using the gel could cycle it hundreds of thousands of times without losing any capacity.
Her team were testing nanowires, a material that is several thousand times thinner than a human hair. The combination, they said, is reliable and resistant to failure. A new smartphone can hold a charge all day with juice to spare – but after 200 recharges, it might need to be recharged before going out for the evening, and after 2000, it’s best not to stray too far from an outlet. Penner said their discovery verifies that nanowire-based batteries indeed have a better lifespan and can soon become a reality.

Senior author Reginald Penner stated that hard work along with luck led to the success of this case. Furthermore, none of the nanowires were damaged, and they believe that the gel plasticized the metal oxide, improving its flexibility. She explained in her findings, published today in the American Chemical Society’s Energy Letters, that after this extended period there was no evidence of capacity or power loss, or frayed nanowires. Researchers at the U.S. Department of Energy’s Argonne National Laboratory have been working on Silicon-based nanowire batteries that could double or even triple the energy stored in conventional batteries.
