Holey Nanocarbon Architectures for High Performance Li-Air Batteries, Year 3
Project Description
Li-air batteries (LABs) have a theoretical energy density of 3500 - 5000 Wh/kg, nearly 10 times that of conventional Li-ion batteries (LIBs). A huge advantage is that the oxygen reactant at the cathode can be directly obtained from air ("air cathode"), thus significant cost and weight reduction of the battery can be obtained. However, major challenges remain for the LAB air cathodes, such as low catalytic efficiency and poor oxygen diffusion during long-term cycling.

Anticipated Benefits
LABs could result in an estimated 80-percent weight savings for energy storage systems in comparison to the LIBs in future "green aviation" aircrafts. LABs are also relevant to crewed space exploratory missions because there will be an oxygen-containing atmosphere in spacecrafts and habitats. LAB technology is expected to have a major national impact on the development of electric and hybrid vehicles and soldier- portable power systems. With some modifications, our material-based electrode technology could also be applied to various battery, supercapacitor, and other energy conversion and storage systems.
