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…

A new paper published in the Journal of The Electrochemical Society, “Mixed Conduction Membranes Suppress the Polysulfide Shuttle in Lithium-Sulfur Batteries,” describes a new battery membrane that makes the cycle life of lithium-sulfur batteries comparable to their lithium-ion counterparts. The research, led by ECS Fellow Sri Narayan, offers a potential solution to one of the biggest barriers facing next generation batteries: how to create a tiny battery that packs a huge punch. Narayan and Derek Moy, co-author of the paper,…

In an effort to develop an eco-friendly battery, researchers from Ulsan National Institute of Science and Technology (UNIST) have created a battery that can store and produce electricity by using seawater. The research is expected to dramatically improve cost and stability issues over the next five years, with researchers confident about commercialization. The driving force behind the battery is the sodium found in seawater. Because sodium is so abundant, the researchers believe that this new system will be an attractive…

By: Jackie Flynn, Stanford University A battery made with urea, commonly found in fertilizers and mammal urine, could provide a low-cost way of storing energy produced through solar power or other forms of renewable energy for consumption during off hours. Developed by Stanford chemistry Professor Hongjie Dai and doctoral candidate Michael Angell, the battery is nonflammable and contains electrodes made from abundant aluminum and graphite. Its electrolyte’s main ingredient, urea, is already industrially produced by the ton for plant fertilizers….
