Battery manufacturer Amprius Technologies is on a mission to reduce EV charging times. The company’s Amprius Extreme Fast Charge feature is enabled by its proprietary Si-Nanowire anode, which is thinner and lighter than conventional graphite anodes, and has much higher conductivity due to the high electrical continuity between silicon and the current collector. The Si-Nanowire… Read more »

DOE study examines how plating causes battery degradation
A new study from DOE’s Argonne National Laboratory seeks to identify the reasons that DC fast charging accelerates battery degradation. The researchers gained some new insights into a process that can cause damage to the anode during charging and discharging. A paper based on the study, “Increased disorder at graphite particle edges revealed by multilength… Read more »
Farasis and Group14 say their silicon-carbon anode delivers 330 Wh/kg
Farasis Energy and Group14 Technologies have developed a new silicon-based anode for an EV-scale battery. In cells built and tested by Farasis using Group14’s silicon-carbon anode material SCC55, the company says it can reach a specific energy of 330 Wh/kg (750 Wh/L energy density) in typical automotive cells, and deliver more than 1,000 charge-discharge cycles….

Is Tesla planning to produce batteries in Quebec?
The Canadian province of Québec seems to be an ideal location for large-scale battery production—it is rich in critical battery metals, and has plenty of cheap and clean hydropower. The provincial government is heavily incentivizing the extraction of key minerals such as lithium, nickel and graphite, and recently announced plans to invest up to 3… Read more »
TE Connectivity’s new connector plating reduces wear on battery terminals
TE Connectivity‘s all-new TENDUR surface plating technology is designed to provide advanced abrasion resistance that allows for consistent high-performance charging over the course of a battery’s lifetime. The technology reduces wear and tear on electrical terminals, which can lead to longer charging times. The newest high-powered charging stations can deliver DC power at currents of… Read more »
Sila’s Drop-In Silicon Anode Technology for Li-ion Batteries
Advancements in the capabilities of lithium-ion batteries have slowed down in the last decade. As conventional electrode materials approach their theoretical limits, substantial gains in battery energy density only come as a trade-off in safety or performance. Kurt Kelty, Vice President of Commercialization for Sila will introduce an innovative drop-in-replacement nanocomposite, silicon-based anode powder that… Read more »
JB Straubel talks Tesla, Redwood and the massive challenge of building an EV supply chain in new video
When I was a kid, everyone had a favorite Beatle (mine was George). Now I have a favorite Tesla co-founder: JB Straubel. He’s a visionary who converted a Porsche to electric drive and built a solar-powered racer, long before EVs were cool. He’s the engineering genius who personally went through and redesigned almost every component… Read more »
Nth Cycle says its electroextraction tech significantly reduces transportation costs for Li-ion battery recycling
Refining the circular economy for battery materials. As the e-mobility transition accelerates, demand for critical minerals is growing exponentially. Companies on the cutting edge, such as Tesla, are already experiencing shortages. However, to extract ever more minerals by mining and dispose of the waste in landfills, would be to continue the practices that got the… Read more »
Janus graphene could boost capacity in sodium-ion batteries
Researchers at Chalmers University of Technology in Sweden have presented a new concept to fabricate high-performance electrode materials for sodium batteries. The results show that the capacity could match lithium-ion batteries. The ions intercalate in the graphite, which means that they can move in and out of the graphene layers and be stored for energy… Read more »
Oil giant Phillips 66 makes strategic investment in battery material supplier Novonix
Multinational oil giants are beginning to invest in companies in several different sectors of the EV industry. Phillips 66 has announced plans to acquire a 16% stake in Novonix, a supplier of materials, equipment and services for the battery industry. Phillips 66 will reportedly pay a total purchase price of $150 million, and will nominate… Read more »
