Additive manufacturing and solid-state battery specialist Sakuu says it has successfully and consistently achieved 3D printing of fully functional batteries in custom shapes and sizes. The batteries were printed as patterned cells containing patterned openings for thermal management on Sakuu’s Silicon Valley battery pilot line—an important step in developing the company’s Kavian platform for the… Read more »

QuantumScape ships first 24-layer prototype battery cells to auto OEMs
Battery developer QuantumScape (NYSE: QS) has shipped its first 24-layer prototype lithium-metal battery cells to automotive OEMs for testing. The company calls the delivery of these A0 samples its key public milestone for the year, and says it represents an important step toward the commercialization of this technology. With the sample cells, the OEMs can… Read more »
Li-ion battery pack prices rise for first time, to $151/kWh
Lithium-ion battery prices have been dropping for so long that industry players and pundits tend to factor ever-cheaper cells into their predictions, and many have made (dubious) comparisons to Moore’s Law, one of the core tenets of the computer industry. Now, thanks to rising raw material and battery component prices, along with more general inflation,… Read more »
University of Michigan to open ceramic ion conductor research center
Ceramic ion conductors for batteries and fuel cells will be the focus of a new research center at the University of Michigan. A four-year DOE grant of $10.95 million will enable UMich to establish a DOE Energy Frontier Research Center for the study of Mechano-chemical Understanding of Solid Ion Conductors (MUSIC), and perform research in… Read more »
Adden Energy receives exclusive tech license and seed funding for solid-state battery scale-up
Solid-state EV battery startup Adden Energy has received an exclusive technology license from Harvard University’s Office of Technology Development, and $5.15 million in seed financing from Primavera Capital Group, Rhapsody Venture Partners and MassVentures. Adden Energy plans to use the funding to scale up a solid-state coin-cell prototype developed by researchers in Xin Li’s Harvard laboratory…. Read more »
ONE’s hybrid battery pack combines the best aspects of two chemistries to deliver 600 miles of EV range
Q&A with ONE CTO Dr. Steven Kaye. There is a wide range of characteristics that describe the performance of any given battery chemistry: energy density, specific energy, specific power, discharge efficiency, self-discharge rate, cycle life, calendar life, and—not the least important—cost. Some types of Li-ion chemistries are really good in a few characteristics but fall… Read more »
Wildcat Discovery Technologies raises $90 million for commercialization of EV “Super Cell”
Battery innovator Wildcat Discovery Technologies has raised $90 million in a Series D funding round led by Koch Strategic Platforms (KSP), a subsidiary of Koch Industries (yes, that Koch Industries). Eastman Kodak (yes, that Kodak) also participated in the round. Wildcat will use the new funds to further develop and commercialize a “Super Cell,” which… Read more »
Brookhaven researchers describe benefits of electrolyte additive
A team led by researchers at DOE’s Brookhaven National Laboratory has investigated the benefits of a lithium difluorophosphate additive for electrolytes in lithium batteries with nickel-rich layered cathodes. According to Brookhaven, the possibility of high-energy-density cells composed of nickel-rich layered cathodes and lithium metal anodes is limited by processes that reduce their capacity. In an… Read more »
The facts about recent electric bus fires in France
False or misleading posts about EV fires flood the internet on a daily basis. The latest spurious sensation was a natural gas-powered bus that caught fire in Italy—a video of the catastrophic conflagration was posted online, and within hours, it had travelled around the world and back again, falsely described as an EV fire. In… Read more »
Sakuu develops the first battery in its new solid-state product line
Additive manufacturing specialist Sakuu has developed a lithium metal battery that achieved an energy density of 800 Wh/l in recent testing. The company says its battery achieves an energy density of 500-700 Wh/l, or greater. It demonstrates an energy retention rate of 97% after 200 cycles, and Sakuu expects it to reach an 80% retention… Read more »
