Cornell researchers’ discovery may lead to safer solid-state batteries
A team of Cornell University researchers has published a paper that reports on their work to fuse together a pair of contorted molecular structures, creating a porous crystal that can uptake lithium-ion electrolytes and transport them smoothly via one-dimensional nanochannels—a design that could lead to safer solid-state lithium-ion batteries. The paper, “Supramolecular Assembly of Fused… Read more »
Ensuring safe and reliable lithium-ion battery performance
Sponsored by Parker Lord. The demand for electric vehicles continues to increase, with EV sales growing faster than any other major category of automobile. According to an article in Forbes, 2023 was the first time more than 1 million EVs were sold in the U.S. in one calendar year, reaching between 1.3 million and 1.4… Read more »
Li-S Energy claims to boost energy density by 45% with new 20-layer lithium-sulfur battery
Li-S Energy has revealed its first 20-layer battery cells using its third-generation semi-solid-state lithium-sulfur (GEN3 Li-S) technology. GEN3 Li-S 20-layer battery cells use a patented low-flammability electrolyte Li-nanomesh technology and Boron Nitride Nanotubes (BNNTs) to prevent dendrite formation. Compared to the company’s second-generation lithium-sulfur cells, the new cells offer greater energy density and more safety,… Read more »
Identifying the root cause of particle contamination in electronic automotive components
Sponsored by Zeiss. Production processes, the production environment, and the final packaging all have an influence on component cleanliness. As a result, compliance agreements with limiting values often need to be implemented between the customer and supplier or between product development and production. This means that the cleanliness requirements are not fixed and can be… Read more »
Thermal runaway early detection: critical sensors and connections for safe battery management
Sponsored by TTI and Amphenol. Battery management systems (BMS)—the electronic brains that monitors and maintains lithium ion battery packs—are essential for the safe and efficient operation of the batteries powering a variety of applications, including electric vehicles. The growth of electric vehicle technology is driven by the desire for reduced emissions, quieter and less expensive… Read more »
Electronics assembly challenges and solutions for the evolving e-mobility landscape
Sponsored by Indium Corporation The e-Mobility Landscape Multiple new EV-only automakers have emerged in recent years—due in part to lower cost of entry, climate change, and environmental government policies—creating a demand to launch new competitive EVs that didn’t exist within the legacy original equipment manufacturer (OEM) marketplace. In this rapidly expanding EV market, reliability and… 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 »
Are solid-state batteries always safer than Li-ion?
Many in the EV industry see solid-state batteries as the future, and one of the reasons is that the more stable solid electrolyte is expected to be safer than current liquid electrolytes. However, new research indicates that the picture may be more complex. A recent study led by the DOE’s Sandia National Laboratories, published in… Read more »
