Electrolyte Genome Could Be Battery Game-Changer

A new breakthrough battery—one that has significantly higher energy, lasts longer, and is cheaper and safer—will likely be impossible without a new material discovery. And a new material discovery could take years, if not decades, since trial and error has been the best available approach. But Berkeley Lab scientist Kristin Persson says she can take some of the guesswork out of the discovery process with her Electrolyte Genome.

Goodbye, Range Anxiety? Electric Vehicles May Be More Useful Than Previously Thought

In the first study of its kind, scientists at Lawrence Berkeley National Laboratory quantitatively show that electric vehicles (EVs) will meet the daily travel needs of drivers longer than commonly assumed. They found that batteries that have lost 20 percent of their originally rated energy storage capacity can still meet the daily travel needs of more than 85 percent of U.S. drivers.

Better Batteries from Berkeley Lab’s Work with Industry

Until recently, it was often difficult for private industry to take advantage of Berkeley Lab’s resources. That has changed with CalCharge, a unique public-private partnership uniting the California Bay Area’s emerging and established battery technology companies with critical academic and government resources.

New Battery Startup Promises Safe Lithium Batteries

Berkeley Lab battery scientist Nitash Balsara has worked for many years trying to find a way to improve the safety of lithium-ion batteries. Now he believes he has found the answer in a most unlikely material—a class of compounds that has mainly been used for industrial lubrication.

Making a Good Thing Better: Berkeley Lab Researchers Open a Possible Avenue to Better Electrolyte for Lithium Ion Batteries

Berkeley Lab researchers carried out the first X-ray absorption spectroscopy study of a model electrolyte for lithium-ion batteries and may have found a pathway forward to improving LIBs for electric vehicles and large-scale electrical energy storage.

DOE Secretary Helps Usher in New Era of Energy Research at Berkeley Lab

Inaugurated today with help from U.S. Department of Energy Secretary Ernest Moniz, Berkeley Lab’s new General Purpose Laboratory will be devoted to flagship centers in materials sciences and energy storage research, as well as to key biosciences programs. Among the building’s new tenants will be the Berkeley Lab site of the Joint Center for Energy Storage Research, or JCESR, a multi-lab program aimed at achieving revolutionary advances in battery performance.

Dispelling a Misconception About Mg-Ion Batteries

Berkeley Lab researchers, working under the JCESR Energy Hub, used supercomputer simulations to dispel a popular misconception about magnesium-ion batteries that should help advance the development of multivalent ion battery technology.

Roots of the Lithium Battery Problem: Berkeley Lab Researchers Find Dendrites Start Below the Surface

Berkeley Lab researchers have discovered that the dendrite problem that can cause lithium-ion batteries to short-circuit, overheat and possibly catch fire originates below the surface of the lithium electrode and not at the surface as has been widely believed.

New Spectroscopic Technique Could Accelerate the Push for Better Batteries

A new technique developed at Berkeley Lab’s Advanced Light Source could help scientists better understand and improve the materials required for high-performance lithium-ion batteries that power EVs and other applications. The technique, which uses soft X-ray spectroscopy, measures something never seen before: the migration of ions and electrons in an integrated, operating battery electrode.

Holistic Cell Design by Berkeley Lab Scientists Leads to High-Performance, Long Cycle-Life Lithium-Sulfur Battery

Researchers at Berkeley Lab have demonstrated in the laboratory a lithium-sulfur (Li/S) battery that has more than twice the specific energy of lithium-ion batteries, and that lasts for more than 1,500 cycles of charge-discharge with minimal decay of the battery’s capacity. This is longest cycle life reported so far for any lithium-sulfur battery.
