batteriesSila Nanotechnologies Silicon anodes will improve lithium ion batteries by up to 40%

No Comments
Sila Nanotechnologies has silicon-dominant anode products that drop into existing battery manufacturing processes, replace graphite entirely, and deliver significantly higher energy density at the cell-level with lower swelling. Sila Nanotechnologies emerged from stealth mode last month, partnering with BMW to …

batteriesVanadium for batteries can be extracted from Canada’s oilsands and potentially double world production

No Comments
Vanadium is a largely obscure metal often used in making steel. It retains its hardness at high temperatures, so it’s ideal for making drill bits, engine turbines and other parts that generate heat. In the oilsands, Vanadium is one of …

commercializationRoll-to-roll chemical vapor deposition system makes long sheets of high quality graphene

No Comments
MIT has combined a roll-to-roll approach — a common industrial approach for continuous processing of thin foils — with the common graphene-fabrication technique of chemical vapor deposition, to manufacture high-quality graphene in large quantities and at a high rate. The …

energyGeneral principles found to speed up the hunt for room temperature superconductors

No Comments
Scientists from Moscow Institute of Physics and Technology and Skoltech have demonstrated the high-temperature superconductivity of actinium hydrides and discovered a general principle for calculating the superconductivity of hydrides based on the periodic table alone. They have used a new …

batteriesJapan finds 400-780 year rare earth supplies in seabed

No Comments
Rare-earth metals are crucial in the making of high-tech products such as electric vehicles, mobile phones and batteries, and the world has relied on China for almost all of its rare-earth material. A seabed off of Japan contains more than …

materialsSystem extracts quarter-liter of water per day per kilogram of MOF from desert air

No Comments
A system, based on relatively new high-surface-area materials called metal-organic frameworks (MOFs), can extract potable water from even the driest of desert air, the researchers say, with relative humidities as low as 10 percent. Current methods for extracting water from …

air forceAir Force and HRL Labs work on promising material for hypersonic vehicles

No Comments
The US Air Force is testing materials produced through ceramic additive manufacturing to advance their potential future use in hypersonic flight vehicles. They are testing additively manufactured silicon oxycarbide (SiOC) materials.The geometric complexity of components that can be produced through …

batteriesBreakthrough for rechargeable non-aqueous magnesium-metal battery that would be twice as good lithium ion batteries

No Comments
Scientists at the Department of Energy’s National Renewable Energy Laboratory (NREL) have discovered a new approach for developing a rechargeable non-aqueous magnesium-metal battery. Scientists have pioneered a method to enable the reversible chemistry of magnesium metal in the noncorrosive carbonate-based …

batteriesThis Unknown Rock Will Revolutionize Transportation

No Comments
We’re facing an imminent crisis in global lithium markets. Demand is growing exponentially, and lithium consumers are facing a 100,000-ton shortfall by 2025. Traditional lithium brine projects take too long to put into production. At up to 48 months, they …
