Everyone loves battery technology improvements. They mean more juice, less heat, smaller batteries, and hopefully fewer fires in our pants. A new battery technology could bring all of those things by drawing power from the air around us.
STAIR (St. Andrews Air) batteries charge just like your normal battery, holding energy between a pair of Lithium/Carbon electrodes. As the battery discharges, though, it takes in oxygen from the surrounding atmosphere to react with the internal carbon, creating more energy. Essentially the battery recharges itself even as it discharges. Since the battery can take oxygen from the air, there’s no need to strap an oxygen tank to your bank to provide the necessary reagent.
