Porous electrodes have been 3D printed in the past using extrusion processes in which a strand of material is extruded from a heated nozzle. Interdigitated, or clasped, structures created with this technique provide space for ion flow, but their limited geometries are quite inefficient. Carnegie Mellon University’s new research has developed a completely different additive process… Read more »

Hyundai invests in solid-state battery materials specialist Ionic Materials
Hyundai’s venture capital division, Cradle, is investing in Massachusetts-based battery materials developer Ionic Materials. Ionic says its patented solid polymer material enables solid-state batteries that are inherently safe, high in energy density and operational at room temperature. The special properties of Ionic’s polymer electrolyte also support lithium-ion cells with little to no cobalt in their cathodes…. Read more »
New solid polymer electrolyte doubles proton flow rate
Engineers from the University of Pennsylvania and the University of Florida have recently made a breakthrough in the development of solid polymer electrolytes (SPEs). Current liquid electrolytes require thick, heavy housings in order to prevent leaks and fires from punctures, increasing their bulk and weight. SPEs solve many of these problems, but until recently, they were… Read more »
Wildcat sorts through the avalanche of new battery materials to find the best
As automakers and cell manufacturers begin to realize the complexity of benchmarking new battery materials, Wildcat Discovery Technology is using its high-speed R&D technology to help find clarity If you follow battery technology news on a regular basis as we do, it’s easy to get overwhelmed by the volume of new announcements. There are… Read more »
Garnet ceramic electrolyte helps block dendrite formation
Researchers at the University of Maryland have developed a new template that they hope will enable a safer alternative to liquid electrolytes, which have several drawbacks, including flammability, leakage and dendrite formation in the electrodes. In “Lithium-ion conductive ceramic textile: A new architecture for flexible solid-state lithium metal batteries,” published in Materials Today, UMD researchers… Read more »
Ionic Materials emerges as a leader in solid-state batteries by focusing on polymer science
Mike Zimmerman, CEO and founder of Ionic Materials, has this to say about his company: “Ionic will play a major role in the solution to the world’s energy problems.” That’s a pretty bold statement. But then again, Mike Zimmerman is a pretty bold man. An experienced polymer scientist, Zimmerman has worked on a number of… Read more »
Ionic Materials raises $65 million to develop its solid-state electrolyte
Ionic Materials has secured $65 million in a Series C financing round from investors in the battery manufacturing, consumer electronic and EV fields, who will be working with the company to speed the development of its solid polymer electrolyte battery material. “This funding round will allow us to add to our talented technical staff while… Read more »
Swiss researchers develop prototype solid-state sodium battery
Researchers from Empa, the Swiss Federal Laboratories for Materials Science and Technology, and the University of Geneva (UNIGE) have built a prototype solid-state battery based on sodium as an alternative to lithium. The scientists described their research in the journal Energy and Environmental Science. Using metallic lithium as an anode material would theoretically increase energy… Read more »
DOE researchers announce major advance toward a solid-state magnesium battery
DOE scientists at the Joint Center for Energy Storage Research (JCESR) have discovered a new magnesium-ion solid-state conductor, a major step towards making solid-state magnesium-ion batteries that are both energy-dense and safe. The liquid electrolyte used in current lithium-ion batteries makes them potentially flammable. Researchers around the world are working to develop a practical solid-state… Read more »
New control strategy enhances battery performance in cold weather
Researchers at Penn State, with a colleague from EC Power, have devised a new control strategy that can rapidly restore EV battery power and permit full regeneration while driving at temperatures as low as -40° C. The strategy involves heating the battery internally during regenerative braking and rest periods. In “Rapid restoration of electric vehicle… Read more »
