Lithium-ion batteries power a vast majority of the world’s portable electronics, but the magnification of recent safety incidents have some looking for new ways to keep battery-related hazards at bay. The U.S. Navy is one of those groups, with chemists in the U.S. Naval Research Laboratory (NRL) unveiling a new battery, which they say is both safe and rechargeable for applications such as electric vehicles and ships. “We keep having too many catastrophic news stories of lithium-ion batteries smoking, catching…

Like all things, batteries have a finite lifespan. As batteries get older and efficiency decreases, they enter what researchers call “capacity fade,” which occurs when the amount of charge your battery could once hold begins to decrease with repeated use. But what if researchers could reduce this capacity fade? That’s what researchers from Argonne National Laboratory are aiming to do, as demonstrated in their open access paper, “Transition Metal Dissolution, Ion Migration, Electrocatalytic Reduction and Capacity Loss in Lithium-Ion Full…

Pennington, NJ – (March 16, 2017) – Lithium-ion batteries power a vast majority of the world’s portable electronics, from smartphones to hoverboards to wireless headphones. While lithium-ion batteries have helped shape the modern world, recent reports of electronics catching fire or exploding have many examining the battery’s safety. K.M. Abraham, Fellow of The Electrochemical Society and professor at Northeastern University, has over 40 years of experience in lithium battery research, with special emphasis on lithium-ion batteries. “It is safe to…

Taking a detailed look inside energy storage systems could help solve potential issues before they arise. A team of researchers from Brookhaven National Laboratory are doing just that by imaging the inner workings of a sodium-metal sulfide battery, leading them to understand the cause of degraded performance. “We discovered that the loss in battery capacity is largely the result of sodium ions entering and leaving iron sulfide—the battery electrode material we studied—during the first charge/discharge cycle,” says Jun Wang, co-author…

John Goodenough may be 94-years old, but he shows no sign of slowing down. Now, the co-inventor of the lithium-ion battery has developed the first all-solid-state battery cells that could result in safer, longer-lasting batteries for everything from electric cars to grid energy storage. “Cost, safety, energy density, rates of charge and discharge and cycle life are critical for battery-driven cars to be more widely adopted,” Goodenough says in a statement. “We believe our discovery solves many of the problems…
