Argonne-led team demonstrates Li-air battery based on lithium superoxide; up to 5x Li-ion energy density

Green Car Congress

Lithium-air batteries form lithium peroxide (Li 2 O 2 )—a solid precipitate that clogs the pores of the electrode and degrades cell performance—as part of the charge−discharge reaction process. This remains a core challenge that needs to be overcome for the viable commercialization of Li-air technology.

3 winners of DOE’s “America’s Next Top Energy Innovator” Challenge: hydrogen-assisted lean-burn engines, graphene for Li-air and -sulfur batteries, and titanium process

Green Car Congress

One negative side effect of a lean burn engine, whether powered by gasoline or diesel fuel, is an increase in the amount of emissions released to the environment. In 2007, Vorbeck signed a worldwide license agreement with Princeton University for a patented method from the the Aksay Labs for manufacturing graphene at commercial scale.

Toyota broadly outlines next-generation Prius; developing wireless inductive charging for the plug-in model; bullish on hydrogen

Green Car Congress

Toyota has also ramped up development on new battery technologies such as solid state and lithium air, as well as devoting resources focused on chemistries beyond lithium, such as magnesium and other low-valence materials. Toyota’s first commercially available hydrogen fuel cell vehicle will go on sale in global markets in 2015.

The Net-Zero Neighborhood: Advanced Energy Storage and Highly Efficient Photovoltaics Take Transportation Off the Gasoline Grid and Residential Off the Electric Grid

Green Car Congress

Actually delivering commercially viable 500-mile batteries will require exascale computing—i.e., Weigand is looking for a “500-mile battery” such as a Li-O 2 (Lithium air) thin film nano-technology system and for 50% efficient photovoltaic cells. Modeling and Simulation at the Exascale for Energy and the Environment (DOE, 2007).
