UT Austin team develops new family of high-capacity anode materials: Interdigitated Eutectic Alloys

Green Car Congress

Researchers in the Cockrell School of Engineering at The University of Texas at Austin have developed a new family of anode materials that can double the charge capacity of lithium-ion battery anodes. It is a simple, low-cost approach that can be applied to a broad range of alloy systems with various working ions such as Li, Na, or Mg.
