Technology Description:

Researchers at Missouri University of Science & Technology (Missouri S&T) are developing an affordable lithium-air (Li-Air) battery that could enable an EV to travel up to 350 miles on a single charge. Today’s EVs run on Li-Ion batteries, which are expensive and suffer from low energy density compared with gasoline. This new Li-Air battery could perform as well as gasoline and store 3 times more energy than current Li-Ion batteries. A Li-Air battery uses an air cathode to breathe oxygen into the battery from the surrounding air, like a human lung. The oxygen and lithium react in the battery to produce electricity. Current Li-Air batteries are limited by the rate at which they can draw oxygen from the air. The team is designing a battery using hierarchical electrode structures to enhance air breathing and effective catalysts to accelerate electricity production.

Potential Impact:

If successful, Missouri S&T’s new Li-Air battery design would make EVs a cost-competitive and high-performance alternative to gasoline-powered vehicles.


Increased use of EVs would decrease U.S. dependence on foreign oil—the transportation sector is the dominant source of this dependence.


Greater use of EVs would reduce greenhouse gas emissions, 28% of which come from the transportation sector.


This battery would enable an EV to travel from New York City to Richmond, VA (335 miles) on a single charge, for less than $10 on average.
