Research led by UCL has revealed new insights into the workings of a lithium battery by virtually "unrolling" its coil of electrode layers using an algorithm designed for papyrus scrolls. In a recent study, researchers combined X-ray and…

While nothing is perfect, even a one-in-200,000 breakdown of lithium-ion batteries can trigger huge recalls like the 2006 incident of six million Sony lithium-ion packs. Now, scientists are closer to understanding exactly what happens…

When a thin layer of alumina is applied to common cathodes, lithium is trapped in batteries. That limits the number of times a battery can be charged and discharged at full power. But new phenomena being studied by engineers at Rice…

The lithium-ion battery is under attack on numerous fronts as scientists and engineers try to come up with alternatives that are more easily acquired than lithium, more environmentally friendly, and better performing. U.S. reserves of…

With the rated range of most electric vehicles at between 200-250 km on a full charge and many newer models capable of more than 400 km these days, electric vehicles are coming into their own. Infrastructure for recharging is lagging and is…

Flexibles, wearables, foldable phones, and 5G devices would all be well served by high capacity, flexible batteries that can be embedded in wristbands and can share wireless power sharing. So far we’ve made progress on everything but the…

One of the reasons it took so long to develop workable lithium-ion batteries for cars was the inherent instability of lithium, especially during charging. Metallic lithium plating that can occur during extreme temperature fluctuations means…

Generating renewable energy has never been a problem, really. But storing the energy for use when it isn’t possible to generate due to atmospheric conditions has always been a challenge. Giant batteries designed for the electrical…

A research team led by the University of California San Diego is challenging current thinking about why lithium metal batteries fail. Researchers discovered the root cause of lithium metal batteries failure is actually bits of lithium metal…

As we continue to demand more of our batteries—smaller, cheaper, and yet with greater capacity—the limitations of lithium-ion become more apparent and scientists continue to try to find alternatives that will do everything lithium-ion can…
