Scientists at the U.S. Department of Energy's Argonne National Laboratory have demonstrated that the design and placement of a tiny measurement device called a reference electrode enhances the quantity and quality of information that can be extracted from lithium-ion battery cells during cycling.
Ionic transport has been studied extensively over the years for energy devices such as fuel cells and batteries using Li+, H+, Ag+, Cu+, F-, and O2-. Yet as Genki Kobayashi and Ryoji Kanno point out in a recent report, hydride ions (H-) may be particularly useful for high-energy-density storage and conversion devices. Using an oxyhydride solid state cell they have now demonstrated pure H- conduction in an oxide for the first time.
Chemists at The University of Texas at Arlington have devised a safer, more environmentally friendly, less expensive and more efficient water-based system for the synthesis of organic compounds typically used in pharmaceuticals, agrochemicals, cosmetics, plastics, textiles and household chemicals.
With people wanting to use smaller electronic devices, smaller energy storage systems are needed. Researchers of Aalto University in Finland have demonstrated the fabrication of electrochemically active organic lithium electrode thin films, which help make microbatteries more efficient than before. Researchers used a combined atomic/molecular layer deposition (ALD/MLD) technique, to prepare lithium terephthalate, a recently found anode material for a lithium-ion battery.
A decade ago, Donald Sadoway, a MIT professor, and his students developed liquid metal batteries, which now appear to be a potential solution to make renewable energy more affordable and practical. These batteries are capable of storing huge amounts of energy, and can balance the fluctuations of production and consumption of power. Ambri, a Cambridge-based startup company, is now in the process of commercializing these liquid metal batteries.
An innovative method for the stabilization of a multiply charged anion (negative ion) has been demonstrated by the researchers at New Virginia Commonwealth University. The study findings have the potential to help produce better magnesium and lithium ion batteries.
A team from Helmholtz-Zentrum Berlin has been able for the first time to measure how new bonds influence molecules: they have reconstructed the “energy landscape” of acetone molecules using measurement data from the Swiss Light Source (SLS) of the Paul Scherrer Institut, and thereby empirically established the formation of hydrogen bonds between acetone and chloroform molecules. The results have been published in Nature Scientific Reports and assist in understanding fundamental phenomena of chemistry.
Scientists have successfully integrated hypothetical calculations and sophisticated in-situ microscopy to reveal critical clues about the properties of an advanced energy storage material for use in batteries and supercapacitors. The study was conducted by researchers from Oak Ridge National Laboratory (ORNL) of the Department of Energy (DOE).
A breakthrough method, developed by a team of researchers headed by the City College of New York chemist Mahesh K. Lakshman, reduces the barrier that inhibits the easy formation of new molecules. The novel technique facilitates the generation of new molecules by cleaving typically inert bonds.
Driven by large and widespread feedstocks and government incentives, Southeast Asia is positioned to be a hub for bio-based materials and chemicals (BBMC), according to Lux Research.
