IIT, Argonne team designs Li2O-based Li-air battery with solid electrolyte; four-electron reaction for higher energy density

Green Car Congress

Researchers at the Illinois Institute of Technology (IIT) and US Department of Energy’s (DOE) Argonne National Laboratory have developed a lithium-air battery with a solid electrolyte. A lithium-air battery based on lithium oxide (Li 2 O) formation can theoretically deliver an energy density that is comparable to that of gasoline.

PNNL team uncovers reaction mechanisms of Li-air batteries; how batteries blow bubbles

Green Car Congress

Lithium-air batteries are looked to by many as a very high-energy density next-generation energy storage solution for electric vehicles. However, the technology has several holdups, including losing energy as it stores and releases its charge.The reaction mechanisms are, in general, not well understood.

IBM releases fifth annual Next Five in Five list of near-term significant innovations; personalized routing for commuting/transportation makes the cut

Green Car Congress

Also on the list of five is the arrival of advanced batteries, including air batteries (e.g., Lithium air), but targeted initially at small devices. Batteries today have a number of problems, chiefly, the heavy metal-oxides used inside the battery greatly limit the amount of energy it can store, IBM notes. Earlier post.).
