Northwestern University researchers used a Birch reduction-inspired solvated electron solution to relithiate chemically degraded NMC532 within seconds at room temperature, followed by a three-hour oxygen anneal to restore its near-surface structure. In lithium-metal half cells, the regenerated cathode delivered 159.49 mAh/g and retained 94.10% of its capacity after 100 cycles, although the researchers tested laboratory-generated model end-of-life material rather than cathodes recovered from retired batteries.
A pioneering ultra-low carbon brick made from near 100% recycled construction waste has been used to create the striking colorful façade of one of London's most anticipated new cultural buildings.
Researchers reviewed advances in alloy-based anodes for rechargeable magnesium batteries, comparing Mg-free hosts, Mg-containing alloys and alloy-derived surface modifications as routes to improve reversibility, Mg²? transport and electrolyte compatibility. The review finds that material structure and interphase chemistry strongly influence performance, while higher alloy-anode operating potentials can reduce full-cell voltage, and practical validation remains a major research priority.
As the global energy demand continues to grow — driven in part by the rise of artificial intelligence — researchers are exploring technologies that can provide affordable, reliable, and safe sources of electricity.
Lithium metal anodes offer a theoretical energy density nearly double that of conventional graphite anodes - 454 Wh kg-1 compared to 314 Wh kg-1 at the cell level when paired with lithium nickel cobalt aluminum oxide cathode.
Because many natural and industrial processes rely on the transport of bubbles and droplets through fluids, the behavior of ordinary air bubbles and water droplets has been well documented.
Until now, it has been almost impossible to measure the energy density of hydrogen precisely, but a new sensor can register every single molecule. This could lay the foundation for correct accounting in the hydrogen economy.
A signal that appears to show ions moving inside a battery may, in fact, be an illusion caused by an uneven surface. A KAIST research team has identified the origin of this type of artifacts, which can lead researchers to misinterpret what is happening inside a battery, and has developed a method to reduce it. The findings are expected to enable more accurate analysis of ion movement and improve the reliability of next-generation battery-material development, including that of solid-state and sodium-ion batteries.
Future lunar bases will depend on materials that can withstand radiation, extreme temperatures, vacuum, and abrasive dust while supporting power generation, storage, and transmission at increasingly large scales. The review highlights how radiation-tolerant photovoltaics, regolith-based thermal storage, lunar-derived conductors and other ISRU-compatible materials could reduce launch mass and help enable more resilient lunar energy infrastructure.
Bruker today announced the launch of the XFlash® 7200 FIRE, the world’s first inclined large-area Energy-Dispersive Spectroscopy (EDS) detector for Scanning Electron Microscopy (SEM) built on Bruker’s revolutionary four-segment Silicon Drift Detector (SDD) architecture.
