Description
Akihiro Nomura and Kimihiko Ito published a battery study in twenty twenty-six on an air electrode that lets lithium-air batteries breathe ordinary air. Such batteries promise far higher energy density than lithium-ion, but in normal air, at only about twenty-one percent oxygen, their pores clog and power dies early. The electrode's pore architecture is the bottleneck.
Their design bonds a carbon nanotube layer to a carbon paper gas layer. Imaging showed pores grading continuously from nanometers to micrometers, keeping oxygen flowing to every reaction site. Discharge stayed fast and cycle life lengthened in plain atmospheric oxygen. Stacked cells produced a lightweight amp-hour-class battery. The authors call it a step toward true air-breathing operation.
