lithium ion

by Jon Gabay, engineer We are so manipulated in our society. Others dictate the technologies we will use and depend on without regard to ramifications. Poor planning and hip-shot reactions lead to wasted time and money, and the goals…

Now there’s an easily fabricated, high-performance carbon microlattice electrode that may result in cheaper batteries powered by sodium ions. Tohoku University published the approach in the journal Small. Lithium-ion batteries are…

With lithium-ion batteries powering almost all remote devices, their manufacturers have had to develop safety measures to limit peak voltage. These include devices that monitor charge-state and current flow, record the latest, full-charge…

Smartphone components generate sound waves at extremely high frequencies ranging from 100 million to 10 billion hertz. In phones, these devices are used mainly to filter the wireless cellular signal and identify and filter voice calls 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…

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…

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…
