U-M leads new DOE-funded research center for ceramic ion conductors; MUSIC

Green Car Congress

The four-year DOE grant establishes a DOE Energy Frontier Research Center (EFRC) at U-M, the Mechano-chemical Understanding of Solid Ion Conductors (MUSIC). And they’ll examine how the introduction of ceramic ion conductors impacts degradation in lithium metal, sodium metal and other solid state configurations.

Spontaneous formation of hollow structures in alloy anode crystals can improve battery stability

Green Car Congress

Now, researchers at Georgia Tech, with colleagues at ETH Zürich and Oak Ridge National Laboratory, have discovered that sufficiently small antimony nanocrystals spontaneously form uniform voids on the removal of lithium, which are then reversibly filled and vacated during cycling, allowing more ion flow without damaging the anodes.

ARPA-E Awards $151M to 37 Projects for Transformative Energy Research

Green Car Congress

The awarded grants will go to projects with lead researchers in 17 states. Eagle Picher, in partnership with the Pacific Northwest National Laboratory, will develop a new generation of high energy, low cost planar liquid sodium beta batteries for grid scale electrical power storage applications.
