A team co-led by UCLA has revived an Edison-style nickel-iron battery that charges in seconds and survives 12,000 cycles, turning a century‑old curiosity into a serious option for long‑term energy storage. By reworking materials that Thomas Edison first tried to use for electric vehicles in 1901, the scientists have created a device that behaves less like a fragile phone battery and more like a durable piece of infrastructure.
This Edison-inspired chemistry points to a different way of thinking about batteries, one where extreme longevity and safe, fast charging matter as much as raw energy density. That shift could prove crucial for the power grid as well as for cars, especially as utilities and drivers look for storage that can last decades instead of years.
From Edison’s 1901 dream to UCLA’s lab
Thomas Edison did not just light homes; he also tried to electrify transport. In 1901 he set out to build an electric car battery based on nickel and iron, hoping to power early vehicles with a rechargeable pack that could handle daily use. The chemistry was durable but slow to charge, and his design never became the standard for vehicles, which instead moved toward lead‑acid and, much later, lithium‑ion cells.
More than a century later, an international research collaboration co‑led by UCLA researchers has developed a new nickel‑iron battery that revives this idea with modern materials science. The Edison‑inspired device now charges in seconds rather than hours, according to the team, directly fixing the flaw that limited Edison’s original system and turning an old concept into a modern prototype for grid and vehicle storage.
How a nickel-iron cell charges in seconds
Fast charging usually comes with trade‑offs. Push lithium‑ion cells too hard and they heat up, degrade, or in extreme cases fail. The new nickel‑iron design takes a different route by focusing on how much of the active material actually participates in the reaction. When particles are made very small, ions and electrons do not have to travel far, which speeds up the flow of charge without putting the structure under the same kind of stress.
Researcher Maher El‑Kady explained that when the particles are tiny, almost every atom can join the chemical reaction, which he called “a huge advantage for batteries,” in comments reported in a recent interview. Earlier tests with a prototype cell showed that it could recharge in mere seconds and repeat that rapid recharge behavior, according to coverage of the prototype device. That combination of speed and repeatability is what separates a lab stunt from a technology with practical promise.
Why 12,000 cycles over decades matters
Charging speed gets attention, but cycle life is where this battery starts to look like infrastructure. The Edison‑inspired nickel‑iron cell is reported to survive 12,000 charge and discharge cycles, and researchers say that level of endurance can stretch across decades of use. Many consumer lithium‑ion packs are rated for only a few hundred to a couple thousand cycles before their capacity fades, which is why phones and laptops feel worn out after a few years.
In grid terms, 12,000 cycles could cover daily cycling for more than 30 years if performance holds outside controlled tests. Reporting on the Edison‑inspired battery notes that the team expects the technology to help stabilize power by soaking up extra electricity when supply is high and releasing it when demand spikes. That framing treats the cell less like a disposable component and more like a long‑lived asset, closer to a transformer or a substation than to a phone battery that needs replacing every few years.
Second life for a “failed” idea
For decades, Edison’s nickel‑iron work was often described as a dead end, especially once lithium‑ion chemistry took over everything from smartphones to electric cars. Coverage of the new research has leaned on that narrative, calling it a second chance for a failed rechargeable battery. Yet the original design did not so much fail as arrive before tools like nanoscale manufacturing and advanced electrolytes were ready to make it shine.
Recent analysis explains how a rechargeable battery based on technology pioneered by Thomas Edison may finally get its due, especially as the world confronts the destructive consequences of fossil fuels and looks for safer, longer‑lived storage options, according to a report in Popular Science. Earlier reporting on the same line of work notes that Edison’s rechargeable battery may get a second life as researchers revisit its chemistry with modern tools, shifting its image from historical curiosity to active candidate for future storage and showing how changing needs can revive old ideas.
EVs, the grid and what happens next
The most obvious application for a battery that charges in seconds and survives 12,000 cycles is transport. Thomas Edison tried to build an EV battery in 1901, and scientists have now made that EV battery concept work at the prototype level, according to reports that describe how they “made Edison’s EV battery work” in practice. In those early tests, the prototype could handle rapid recharge behavior over many runs, suggesting that ultra‑fast top‑ups might be possible for future vehicles that use this chemistry.
The biggest impact, however, may come on the grid rather than in cars. The team expects the Edison‑inspired technology to stabilize power, and that goal fits the strengths of nickel‑iron: long life, tolerance for frequent cycling, and the ability to sit in one place for decades. If a rechargeable battery based on Edison’s ideas can charge in seconds and endure 12,000 cycles, as described in coverage of the new work, it could act like a shock absorber for a grid dominated by wind and solar, smoothing out the jagged edges of supply without constant replacement.
