Supported by an ARPA-E grant, LiRAP has proven to be a safe alternative compared to the liquid electrolytes used in most of today’s lithium ion batteries. The LiRAP solid electrolytes conduct Li + ions well at high voltage and high current, providing much enhanced energy density and power capacity as well as safety. Braga, J.A.

Out of several candidates that could replace Li in rechargeable batteries, calcium (Ca) stands out as a promising metal. Not only is Ca 10,000 times more abundant than Li, but it can also yield—in theory—similar battery performance. Haesun Park, Chung-Ang University, co-corresponding author. —Prof.

E-bike powered by Faradion prototype Na-ion battery pack. British battery R&D company Faradion has demonstrated a proof-of-concept electric bike powered by sodium-ion batteries at the headquarters of Williams Advanced Engineering, which collaborated in the development of the bike. Oxford University was also a partner.

in partnership with Kyoto University, has developed a lower temperature molten-salt rechargeable battery that promises to cost only about 10% as much as lithium ion batteries. A drawback to the general class of molten salt batteries has been high operating temperatures. The Nikkei reports that Sumitomo Electric Industries Ltd.,

Researchers at the University of Texas, including Dr. John Goodenough, are proposing a strategy for high-capacity next-generation alkali (lithium or sodium)-ion batteries using water-soluble redox couples as the cathode. The present sodium-sulfur battery operates above 300 °C. A typical Li-air battery discharges at 2.5-2.7

Most electrolytes currently used in Li-ion batteries contain halogens, which are toxic. An in-depth study based on first-principles calculations by researchers at Virginia Commonwealth University has shown that the anions of commercially available electrolytes for Li-ion batteries are all superhalogens.
