BASF markets anode binders for Li-ion batteries
Battery manufacturers are striving to increase capacity, reduce charging time and ensure an adequate supply of raw materials. BASF developed its new Licity range of binders in order to meet these needs. Depending on their requirements, customers can choose a series with a certain application focus, such as binders suitable for pure graphite or silicon-containing anodes…. Read more »
Norwegian silicon provider Elkem secures grant to plan new battery material plant
Norwegian silicon specialist Elkem has received 10 million Norwegian Kroner (about $1.1 million) in financial support from Enova, a Norwegian government enterprise that supports the development of clean energy technology. The company will use the funds for initial planning of a large-scale battery materials plant. Elkem’s Northern Recharge project aims to supply the fast-growing battery… Read more »
Enovix secures $45 million to commercialize 3D Silicon Lithium-ion Battery
Enovix Corporation has secured an additional $45 million to produce and commercialize its 3D Silicon Lithium-ion Battery. Enovix CEO Harrold Rust said, “Anchoring the round is a $25-million strategic investment from a leading California technology company. Present investors have added $10 million, and customers have contracted $10 million to develop batteries for specific products and… Read more »
Enevate says its new silicon-dominant battery tech enables 5-minute charge
Enevate, a battery technology company based in Irvine, California, has launched its fourth-generation XFC-Energy battery technology, which offers 800 Wh/L cell energy density and achieves five-minute charging to 75 percent capacity, according to the company. The XFC-Energy technology is designed for large-format pouch, prismatic, and cylindrical EV cells. It uses pure silicon anode technology with… Read more »
Battery testing start-up Novonix has spun off PUREgraphite to manufacture anode material in the US
Batteries are ubiquitous in our modern lives. Take a look around you and count how many items need be plugged in and recharged. If you’re at your desk, the answer might be four or five. If you’re out for a run, perhaps two or three. If you’re in a garage, there may only be one,… Read more »
Amprius’s silicon nanowire batteries power the Zephyr S HAPS solar aircraft
Battery manufacturer Amprius is supplying lithium-ion cells to Airbus’s Zephyr program. Using Amprius’s cells, which contain a 100% silicon anode, the Zephyr S solar-powered unmanned aerial vehicle (UAV) recently flew more than 25 days, setting a new record for stratospheric flight. The Zephyr S is a high-altitude pseudo-satellite (HAPS), which combines the persistence of a… Read more »
Adding graphene girders to silicon electrodes could double battery life
Graphite has long been the default choice of material for anodes, but researchers dream of replacing graphite with silicon, which has ten times the gravimetric energy density. Unfortunately, silicon has several issues that limit its commercial use – it expands during lithiation, causing particles to agglomerate in ways that impede efficiency, and it is not… Read more »
3M sells NMC cathode patents to Umicore, will focus on Si anodes
3M has agreed to transfer all of its intellectual property related to Nickel-Manganese-Cobalt (NMC) cathodes, including global patents and license agreements, to technology and recycling firm Umicore. The divestment will allow 3M to increase its focus on next-generation silicon anode materials, electrolyte additives and advanced thermal management solutions for EVs. “The agreement enables 3M to… Read more »
Researchers develop new silicon-sulfur-graphene electrode material
Researchers from the University of Waterloo and GM’s Global Research and Development Center have developed a new silicon-based anode material that they say could enable batteries with almost 10 times more energy density than today’s state of the art. In “Evidence of covalent synergy in silicon–sulfur–graphene yielding highly efficient and long-life lithium-ion batteries,” published in… Read more »
