Argonne National Laboratory, which has contributed heavily to the research and development of Li-ion battery technology, is now pursuing research into Lithium-air batteries. Li-air batteries use a catalytic air cathode that converts oxygen to lithium peroxide; an electrolyte; and a lithium anode.

Photosynthetic processes used by plants or algae use sunlight to convert atmospheric CO 2 to energy-rich metabolites (carbohydrates, lipids, or hydrocarbons) which can be processed into transportation fuels. Solar photovoltaic (PV) devices harvest and convert sunlight directly to electricity. Photovoltaic Solar Energy.

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.

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. Water will be the primary byproduct. Engineering E.
