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.

Goodenough and UT team report new strategy for all-solid-state Na or Li battery suitable for EVs; plating cathodes

Green Car Congress

Replacing a conventional host insertion compound as a cathode by a redox center for plating an alkali-metal cathode provides a safe, low-cost, all-solid-state cell with a large capacity resulting in high energy density and a long cycle life. Using the new glass, the cathode consists of plating the anode alkali-metal (e.g., Braga et al.
