In a pair of papers published in Nature Communications and Physical Review Letters, a team of scientists at Lawrence Berkeley National Laboratory has come up with a set of rules for making new disordered materials, a process that had previously been driven by trial-and-error. They also found a way to incorporate fluorine, which makes the material both more stable and have higher capacity.
Hydro-Québec and Lawrence Berkeley National Laboratory have agreed to explore collaborations toward the research and development of manufacturing and scale-up technology to advance transportation electrification and energy storage.
Lithium-sulfur batteries have great potential as a low-cost, high-energy, energy source for both vehicle and grid applications. However, they suffer from significant capacity fading. Now scientists from the Lawrence Berkeley National Laboratory have made a surprising discovery that could fix this problem.
Using advanced imaging techniques, scientists at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have been able to observe what exactly happens inside a cathode particle as lithium-ion batteries are charged and discharged. In a research project led by Berkeley Lab materials chemist Guoying Chen, the researchers uncovered important insights into reactions in
A new X-ray microscopy technique has given scientists the ability to image nanoscale changes inside lithium-ion battery particles as they charge and discharge. The real-time images provide a new way to learn how batteries work, and how to improve them.
The Materials Project, a Google-like database of material properties aimed at accelerating innovation, has released an enormous trove of data to the public, giving scientists working on fuel cells, photovoltaics, thermoelectrics, and a host of other advanced materials a powerful tool to explore new research avenues. But it has become a particularly important resource for researchers working on batteries.
A team led by Gerbrand Ceder has made a major advance in understanding the chemical processes in “lithium-rich cathodes,” which hold promise for a higher energy lithium-ion battery.
Lithium nickel manganese cobalt oxide, or NMC, is one of the most promising chemistries for better lithium batteries, especially for electric vehicle applications, but scientists have been struggling to get higher capacity out of them. Now researchers at Lawrence Berkeley National Laboratory have found that using a different method to make the material can offer substantial improvements.
Scientists at Lawrence Berkeley National Laboratory have developed a novel electrolyte for use in solid-state lithium batteries that overcomes many of the problems that plague other solid electrolytes while also showing signs of being compatible with next-generation cathodes.
More than 200 people attended the 2015 Bay Area Battery Summit at Lawrence Berkeley National Laboratory on Nov. 3 to discuss how to promote transformative energy storage technologies. The purpose of the Summit was to bring scientists together with policymakers and business to discuss what more could be done—whether in labs, universities, industry, Congress, or
