Discovery Could Energize Development of Longer-Lasting (lithium-air) Batteries

May 23, 2016
[font size=3]A UT Dallas researcher has made a discovery that could open the door to cellphone and car batteries that last five times longer than current ones.
Dr. Kyeongjae Cho, professor of materials science and engineering in the Erik Jonsson School of Engineering and Computer Science, has discovered new catalyst materials for lithium-air batteries that jumpstart efforts at expanding battery capacity. The research was published in Nature Energy.
…
Lithium-air (or lithium-oxygen) batteries "breathe" oxygen from the air to power the chemical reactions that release electricity, rather than storing an oxidizer internally like lithium-ion batteries do. Because of this, lithium-air batteries boast an energy density comparable to gasoline — with theoretical energy densities as much as 10 times that of current lithium-ion batteries, giving them tremendous potential for storage of renewable energy, particularly in applications such as mobile devices and electric cars.
For example, at one-fifth the cost and weight of those presently on the market, a lithium-air battery would allow an electric car to drive 400 miles on a single charge and a mobile phone to last a week without recharging.
