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.
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.
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.
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.”
Berkeley Lab spin-off company PolyPlus is making big strides in lithium-metal batteries, but there are research challenges and opportunities ahead.
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
U.S. Secretary of Energy Steven Chu announced a multi-partner team which includes Lawrence Berkeley National Laboratory (Berkeley Lab) for an award of up to $120 million over five years to establish a new Batteries and Energy Storage Hub. The Hub, to be known as the Joint Center for Energy Storage Research (JCESR), will be led by Argonne National Laboratory.
CalCEF, which creates institutions and investment vehicles for the clean energy economy, and Lawrence Berkeley National Laboratory (Berkeley Lab) today announced a partnership to launch CalCharge, a consortium uniting California’s emerging and established battery technology companies with critical academic and government resources.
Lawrence Berkeley National Lab Director Paul Alivisatos today praised the agreement reached by the State of California, which frees some $100 million in funding for a statewide network of charging stations for zero emission vehicles.
New materials are crucial to building a clean energy economy—for everything from batteries to photovoltaics to lighter weight vehicles—but today the development cycle is too slow: around18 years from conception to commercialization. To speed up this process, a team of researchers from the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) and the Massachusetts Institute of Technology (MIT) teamed up to develop a new tool, called the Materials Project, which launches this month.
