UC Irvine researchers have found a process that might change the way batteries are made in the future. Imagine a battery that never has to be recharged and could possibly power your home or automobile. Amazing discoveries that have a big influence on future energy consumption can be made when patience and good fortune combine. As a result, Mya Le Thai, a doctoral student in chemistry at the University of California, Irvine, accidentally invented a mechanism that allows a battery to hold charges indefinitely. With nanowire-based battery material that can be recharged indefinitely, we are moving closer to a battery that will never need to be replenished.Mya was working with various materials in the lab when she decided to cover some gold nanowires with a very thin gel coating. Because of the thin gel that covers the wires, the capacitor's filaments retain their properties even after hundreds of thousands of charges.
The new batteries are being created at GE Research in Niskayuna, which serves as GE's principal research center, as part of a Department of Defense commitment to build batteries that last longer and are more durable.The new batteries are being developed at GE Research in Niskayuna, which serves as GE's major research site, as part of a Department of Defense push to develop longer-lasting and more durable batteries.

What if the chemical processes of simpler, non-living systems, such as batteries, could be programmed to prevent degradation and extend life?To prevent pieces from going down, biological systems use sophisticated chemical interactions and feedback to extend their longevity. What if the chemical processes in simpler, non-living systems, such as batteries, could be programmed to avoid degradation and extend life? "When someone has a cut, you can apply an antibiotic ointment to stop infection and speed up the healing of a lesion." "What we're innovating is more proactive," says Sreekar Karnati, a chief engineer at GE Research's Advanced Manufacturing Lab. Rather than letting the metal to corrode and pit, "we're constructing a protective surface layer on aluminium alloys that can self-heal, or renew."According to GE, the new durable batteries will be used in automobiles, planes, and critical infrastructure in the future.
Consider a battery that can be charged indefinitely. There will be no more discarded cell phones due to depleted batteries. There will be no more lithium ion battery disposals.This is one step closer to becoming a reality thanks to the work of researchers at the University of California, Irvine. The discovery that might lead to exceptionally long-lasting batteries was made by chance. Nanowires are incredibly tiny conductive wires with huge application potential in batteries. A group of researchers led by Reginald Penner, chair of the chemistry department at the university, had been investigating nanowires. Nanowires are fragile, and after a certain number of charging cycles, they generally fray and break.
One day, Mya Le Thai, a PhD student in Penner's lab, made the haphazard choice to change the liquid electrolyte that surrounded the nanowire assembly with a gel electrolyte. "She started to cycle these gel capacitors," Penner says, "and that's when we got the surprise." "This thing has cycled 10,000 times and is still running," she said. She returned a few days later and reported, "It has cycled for 30,000 cycles." That went on for a month. One day, Mya Le Thai, a PhD student in Penner's lab, made the haphazard choice to change the liquid electrolyte that surrounded the nanowire assembly with a gel electrolyte.The group realized they were dealing with a one-of-a-kind situation. They do, however, have an explanation for why using a gel electrolyte appears to prevent nanowire disintegration. According to Penne, the gel has the consistency of peanut butter.Eighty percent of the manganese oxide nanowires are porous, despite being hundreds of times thinner than human hair. The nanowires soften when the viscous gel pours into their pores over time.
This tenderness softens their fragility. Penner claims that "the nanowires start to disintegrate after 5,000 cycles with regular liquid." After then, they begin to fall off. Nothing like that is happening in the gel.The team is presently working to put this notion to the test. If it is correct, they will continue to test other materials and gels to see which ones perform best. If the findings holds up, gel-wrapped nanowires might one day be employed as a component in extraordinarily long-lasting batteries. Penner says that, while he has received calls from firms interested in the work his lab has generated, he believes this is still some years away.According to Penner, the larger picture is that stabilizing the type of nanowires studied might be performed in a reasonably simple method. "The community would benefit greatly if this is generally true."A battery that lasts ten or two years might easily outlive the device it powers, because the bulk of household devices' longevity is limited by reasons other than battery life. "You might never need to buy two of them if you could get 100,000 cycles out of a lithium ion battery," Penner says. We're talking about a life expectancy of twenty years or more.

If a battery has a lifespan of 10 years or more, it is said to be long-lasting.
