advance in Li-Ion-air battery=4x charge capacity #energy #battery #innovation #IN #VC

Researchers have been exploring how to improve lithium-based batteries to extend their use for electric vehicles and other applications. Now, according to an article on MIT's website , scientists at MIT and Sandia National Labs have observed a reaction in lithium-air batteries that could help improve the design of these types of cells. Lithium-air batteries use an air cathode to draw oxygen from the atmosphere. The oxygen reacts with the lithium to produce electricity. These batteries could store up to four times as much energy per pound as the best lithium-ion batteries on the market today. Their use in electric vehicles could break the mainstream barrier to entry for these vehicles. MIT graduate researchers Robert Mitchell and Betar Gallant connect a lithium-air battery used to prepare the samples for characterization by transmission electron microscope imaging. Research...
