The Battery500 consortium, led by the DOE’s Pacific Northwest National Laboratory (PNNL), intends to build a battery pack with a specific energy of 500 Wh/kg, which would more than double the 170-200 Wh/kg per kilogram in today’s typical EV battery. Part of the initiative is the “Seedling” program, which identifies new and risky battery research… Read more »

MIT-led study suggests route to improving solid-state batteries
Replacing a liquid electrolyte with a solid electrolyte could offer major advantages for both safety and energy storage capacity, but so far, attempts to develop a practical solid-state cell have run into major obstacles. Liquid electrolytes can be flammable, and are also prone to the formation of dendrites -thin, fingerlike projections of metal that build… Read more »
DOE awarding $19 million to 22 advanced vehicle technologies projects
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 »
Funding available for Battery500 Seedling Projects
The DOE is issuing a funding opportunity (DE-FOA-0001629) for the Vehicle Technologies Office (VTO) of up to $19.7 million to support research and development of advanced vehicle technologies. The funding opportunity seeks projects in four areas, including Battery500 Seedling Projects. The VTO Battery500 Consortium has set a goal of doubling the specific energy of lithium… Read more »
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 »
MIT researchers discover two forms of lithium dendrite formation
Battery researchers around the world are working on lithium metal electrodes, which have the potential to greatly increase energy density. But the drawback to lithium in this form comes in the form of dendrites, root-like lithium deposits that form on the metal surface and can harm performance and even lead to short circuits. Now a… 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 »
New study identifies one culprit behind Li-sulfur battery capacity fade
Lithium-sulfur batteries theoretically offer high energy density, and are widely seen as a promising next-generation energy storage system. However – you guessed it – they have several drawbacks. Among other issues, capacity tends to fade quickly. Researchers at the DOE’s Pacific Northwest National Laboratory (PNNL) have identified one of the reasons behind this problem, and found… 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 »
