New nanolithia cathodes may address technical drawbacks of Li-air batteries; scalable, cheap and safer Li-air battery system

Green Car Congress

Conventional lithium-air batteries draw in oxygen from the outside air to drive a chemical reaction with the battery’s lithium during the discharging cycle, and this oxygen is then released again to the atmosphere during the reverse reaction in the charging cycle. —Zhu et al.

ARPA-E Selects 37 Projects for $106M in Funding in Second Round; Electrofuels, Better Batteries and Carbon Capture

Green Car Congress

Today’s technologies for making biofuels all rely on photosynthesis—either indirectly by converting plants to fuels or directly by harnessing photosynthetic organisms such as algae. This process is less than 1% efficient at converting sunlight to stored chemical energy. Electrofuels: Biofuels from Electricity. Engineering E.

Researchers Develop Lithium-Water Electrochemical Cell for the Controlled Generation of H2 and Electricity

Green Car Congress

One compartment contains a metallic lithium electrode (anode) in an organic solvent (1m LiClO 4 in ethylene carbonate/dimethyl carbonate), while the other contains an aqueous electrolyte solution (LiNO 3 /H 2 O) with a carbon-based hydrogen generation electrode (cathode). Simultaneously, hydrogen gas is generated on the cathode.
