The scientists were able to encapsulate the lithium metal core using solid electrolyte nanomaterials membranes. The solid electrolyte selectively allows lithium ions to pass through, but impervious to liquids and gases. With this unique design, the lithium core is electrochemically active but chemically isolated from the external electrolyte, enabling the redox reaction of Lithium Air taking place, which creates a remarkable high energy density.
The Team lead by director Lloyd L. Tran is currently developing Lithium Air Technology that can potentially provides 10 times more energy density than the lithium ion battery technologies.
At a nominal electropotential of about 3.27 volts, the theoretical specific energy for a lithium air rechargeable battery is 5,532 Wh/kg , which is about 10 times that of Li-ion battery chemistry that has a theoretical specific energy of about 400 Wh/kg. The Lithium Air Battery technology developed by Lloyd Tran is based on proprietary Nanocomposite Technologies.
The newly developed Lithium Air Technology will be used to power a typical electric ca rto 400-500 miles between charges.
