(Georgia Institute of Technology: Atlanta) -- A research team led by Georgia Tech’s Hailong Chen has developed a low-cost iron chloride cathode for lithium-ion batteries that could radically improve lithium-ion batteries (LIBs), potentially transforming the electric vehicle (EV) market and large-scale energy storage systems.

“For a long time, people have been looking for a lower-cost, more sustainable alternative to existing cathode materials. I think we’ve got one,” says Chen, an associate professor with appointments in the George W. Woodruff School of Mechanical Engineering and the School of Materials Science and Engineering.

The revolutionary material, iron chloride (FeCl3), costs a mere 1–2% of typical cathode materials and can store the same amount of electricity. Cathode materials affect capacity, energy, and efficiency, playing a major role in a battery’s performance, lifespan, and affordability.
