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 »
