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.

New Hybrid Electrolyte For Solid-State Lithium Batteries

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.

Berkeley Lab Hosts Bay Area Battery Summit

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

Battery Mystery Solved: Atomic-Resolution Microscopy Answers Longstanding Questions About Lithium-Rich Cathode Material

Using complementary microscopy and spectroscopy techniques, researchers at Lawrence Berkeley National Laboratory say they have solved the structure of lithium- and manganese-rich transition metal oxides, a potentially game-changing battery material and the subject of intense debate in the decade since it was discovered.

PIMs May Be the Cup of Choice for Lithium-Sulfur Batteries

Berkeley Lab researchers have developed a membrane made from polymers of intrinsic microporosity (PIMs) that extends the life and improves the performance of lithium-sulfur batteries.

Bay Area National Laboratories Jointly Launch New Small Business Voucher Pilot for Emerging Cleantech Companies

Lawrence Berkeley National Laboratory, in partnership with Sandia National Laboratories/California and Lawrence Livermore National Laboratory, has been awarded $4.15 million by the Department of Energy to jointly launch a new small business voucher pilot.

Sensitive and Specific: A New Way of Probing Electrolyte/Electrode Interfaces

Researchers have developed a new technique that enables sensitive and specific detection of molecules at the electrode/electrolyte interface. This new method uses diffraction from graphene gratings to overcome key difficulties associated with traditional optical spectroscopy that employs infrared probing of buried interfaces.

A Bridge to Better Batteries

A major automaker came to Lawrence Berkeley National Laboratory recently wanting to better understand battery degradation. After many months of intense collaborative research with a Berkeley Lab battery scientist, they gleaned some important insights into the conditions that may lead to battery failure, and even published a paper on their findings. Another large car company

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.
