New Studies on Disordered Cathodes May Provide Much-Needed Jolt to Lithium Batteries

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.

Berkeley Lab and Hydro-Québec Announce Partnership for Transportation Electrification and Energy Storage

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.

A Seaweed Derivative Could Be Just What Lithium-Sulfur Batteries Need

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.

High-Resolution Imaging Reveals New Understanding of Battery Cathode Particles

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

New X-Ray Microscopy Technique Images Nanoscale Workings of Rechargeable Batteries

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.

Massive Trove of Battery and Molecule Data Released to Public

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.

New Path Forward for Next-Generation Lithium-Ion 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.

Technique Matters: A Different Way to Make a Cathode May Mean Better Batteries

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.
