The DOE is awarding $19.4 million to 22 new cost-shared research projects in the fields of advanced batteries, lightweight materials, emission control, and energy-efficient mobility systems. Fifteen of these are Phase 1 Battery Seedling projects, aimed at battery materials and approaches that complement the Battery500 Consortium’s research. Promising Phase 1 awardees will be competitively weeded… Read more »

MIT researchers investigate mechanics of sulfide-based solid electrolyte material
IMAGE: Using specialized equipment, a team from MIT did tests in which they used a pyramidal-tipped probe to indent the surface of a piece of the sulfide-based material. Surrounding the resulting indentation (seen at center), cracks were seen forming in the material (indicated by arrows), revealing details of its mechanical properties. Battery scientists are the world are exploring… Read more »
UT Austin team developing solid-state sodium or lithium battery cell
Researchers at the University of Texas at Austin have devised a new strategy for an all-solid-state sodium or lithium EV battery cell. In “Alternative Strategy for a Safe Rechargeable Battery,” published in Energy & Environmental Science, noted lithium-ion battery pioneer Professor John Goodenough and his colleagues explain that the cells use a solid glass electrolyte….

Penn State professor wins grant to develop self-healing layers for Li metal anodes
Donghai Wang, who leads the Energy Nanostructure Laboratory at Penn State, has won a $1.1-million grant from the DOE’s Vehicle Technologies Office to develop a new lithium-ion conductor that will prevent the formation of dendrites, the bane of lithium metal anodes. Wang and his team plan to use thin layers of nanostructured hybrid materials to… Read more »
Sion Power’s Licerion advances Li-metal anode technology
Arizona battery developer Sion Power has reported that one of its Licerion battery systems has achieved specific energy of 400 Wh/kg, energy density of 700 Wh/L and a lifetime of 350 cycles. Dr. Yuriy Mikhaylik, Sion Power’s Director of Materials, presented details at a recent meeting of the Electrochemical Society. Licerion, a product of Sion… Read more »
DOE awards $16 million to 54 projects to commercialize new energy technologies
The DOE has announced nearly $16 million in funding from its Technology Commercialization Fund (TCF), which has a mission to help businesses move promising energy technologies from the DOE’s national laboratories to the marketplace. This round of funding will support 54 projects at 12 national labs, involving 52 private-sector partners. EV-related TCF awards include: Manufacturing… Read more »
LG Chem to license Optodot’s boehmite ceramic-coated battery separators
Optodot Corporation has granted a license to LG Chem for batteries, cells, separators and electrolyte members comprising boehmite, an aluminum oxide hydroxide mineral. The license permits LG Chem to use boehmite separator films for lithium-ion batteries. “Boehmite ceramic coating layers offer a number of distinct benefits in lithium-ion batteries, including improved thermal stability to enhance… Read more »
Stanford team develops Li-metal anodes
Lithium-metal anodes are the favored solution for next-generation Li-air or Li-sulfur batteries for various reasons, including their high specific capacity (theoretically tenfold higher than graphite). However, safety issues resulting from dendrite formation and instability caused by volume expansion have slowed the development of commercially viable solutions. In “Composite lithium metal anode by melt infusion of… Read more »
A closer look at electrolytes in advanced batteries
The electrolytes in advanced batteries are based on incredibly complicated formulations. If you calculated all of the possible combinations of solvents, salts and additives while trying to find the optimal ratios for just one electrolyte formulation, it would add up to an extraordinary number of possibilities. Because it plays such a critical role in battery… Read more »
Sony working on high-capacity lithium-sulfur and magnesium-sulfur batteries
Sony, the company that introduced the world’s first commercial lithium-ion battery in 1991, is already well along the road to a Li-ion replacement, according to Nikkei Technology. The company is reportedly developing high-capacity lithium-sulfur and magnesium-sulfur batteries, aiming for a 40% increase in volumetric capacity to 1,000 Wh/l, and plans to commercialize the new chemistries… Read more »
