Chemists from the University of Waterloo have successfully resolved two of the most challenging issues surrounding lithium-oxygen batteries, and in the process created a working battery with near 100% coulombic efficiency. A) Gibbs reaction energy for formation of Li 2 O and Li 2 O 2 as a function of temperature. —Linda Nazar.
Researchers at George Washington University led by Dr. Stuart Licht have introduced the principles of a new class rechargeable molten air batteries that offer amongst the highest intrinsic electric energystorage capabilities. In 2008 a zirconia stabilized VB 2 air battery was presented. Earlier post.] —Licht et al.
Current topics of interest include: Biomass Conversion, Biofuels & Bioenergy. Advanced Batteries for Transportation and Renewable EnergyStorage. The focus is on high-energy density and high-power density batteries suitable for transportation and renewable energystorage applications.
The new catalyst, reported in an open source paper in Nature Communications , could pave the way for reliable, economical metal-air batteries and alkaline fuel cells, providing for practical use of wind- and solar-powered electricity, as well as enhanced hybrid and electric vehicles. —Piotr Zelenay, corresponding author.
The US Department of Energy is awarding $106 million in funding for 37 research projects selected in the second round by the DOE’s Advanced Research Projects Agency-Energy (ARPA-E). Novel Biological Conversion of Hydrogen and Carbon Dioxide Directly into Biodiesel. Batteries for Electrical EnergyStorage in Transportation.
MIT researchers have found a new family of highly active catalyst materials that provides the best performance yet in the oxygen evolution reaction (OER) in electrochemical water-splitting—a key requirement for energystorage and delivery systems such as advanced fuel cells and lithium-air batteries.
The unit cost of batteries will decline with increased production and development; in addition, the energystorage (in kilowatt-hours) required for a given vehicle range will decline with vehicle load reduction and improved electrical component efficiency. Hybrid LDVs might reach 94 mpg (2.5 l/100 km) by 2050.
The solid-state battery, which promises to provide higher energy density, quicker charging, and increased safety, is anticipated to make significant progress towards mass production in 2024. Some other Battery news are, New developments and experiments in battery chemistries like lithium-air and magnesium-ion are going on.
