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.

Berkeley Lab Wins Eight 2013 R&D 100 Awards

A generator that uses a virus to convert mechanical energy to electricity and a new material that will boost power storage in rechargeable batteries by 30 percent are among eight inventions by Berkeley Lab scientists that were honored with a 2013 R&D 100 Award, often dubbed the “Oscars of Innovation.”

Research Opportunities Plentiful for Next Generation Batteries

Berkeley Lab spin-off company PolyPlus is making big strides in lithium-metal batteries, but there are research challenges and opportunities ahead.

To Build a Better Battery: Two Takes on Lithium-ion Batteries from Berkeley Lab Researchers

Lithium-ion batteries have transformed our lives. Without them, we wouldn’t have laptop computers or cell phones — at least, not the long-lived, lightweight kind we’re used to — and in the near future they may become more important yet. With sufficiently powerful batteries, renewable energy and electric cars become viable, but we first need to
