Silicon has long been heralded as the next important anode material. Silicon anodes can theoretically store more than twice as much lithium than graphite anodes used in nearly all Li-ion batteries today. In this session, Ashok Lahiri, Co-Founder & CTO, will share how Enovix’s 3D cell architecture solves the four technical problems of silicon, producing… Read more »

Michigan seems the likely site of Graphex’s new battery materials plant
Graphex Technologies, a subsidiary of Graphex Group, has agreed to form a joint venture with Michigan-based Emerald Energy Solutions to build and operate a graphite processing facility. The JV is considering “several Michigan sites as well as other sites,” and the final site selection is expected in March. Graphex hopes to have a facility operational… Read more »
Our Next Energy tests 750-mile battery pack in a Tesla Model S
A two-year-old Michigan startup, Our Next Energy (ONE), has built a custom battery pack that recently propelled a modified Tesla Model S for 752 miles. John Voelcker, writing in Car and Driver, reports that ONE retrofitted the car with a pack that stores twice the energy of Tesla’s original, and fits in exactly the same… Read more »
JAIST anode material may improve battery charge time and durability
Scientists at the Japan Advanced Institute of Science and Technology—a graduate school and research university—have developed a new carbon-based anode material that may increase the durability of batteries and shorten charging times. The scientists calcinated a polymer called polybenzimidazole at 800 degrees Celsius to construct a carbon-based anode with 17 percent nitrogen, then tested it…. Read more »
Amprius’s Si-Nanowire anode shortens charging time
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 »
