UT and ORNL researchers develop new class of pseudocapacitor; anion-based intercalation pseudocapacitance

Green Car Congress

Unlike other devices, the team’s is the first to utilize oxygen anions (negatively-charged ions) instead of cations (positive ions) to store its energy. The device uses a perovskite material (LaMnO 3 ), a structure containing vacant sites where oxygen anions can be stored, making these advancements a possibility.

Goodenough perspective on Li-ion batteries; in transportation, PHEVs for the near-term, longer term requires new electrochemical strategies

Green Car Congress

John Goodenough at the University of Texas at Austin and colleague Kyu-Sung Park have written a perspective paper on Li-ion batteries (LIBs), published in the Journal of the American Chemical Society. More recently, at the University of Texas, Austin, Dr. Goodenough patented a new class of iron phosphate materials. Earlier post.).

New cathode design and understanding of electrolyte delivers greater efficiency in magnesium-ion batteries

Green Car Congress

Magnesium rechargeable batteries (MRBs) are emerging as an attractive candidate for energy storage in terms of safety, energy density, and scalability because magnesium metal has ideal properties as a battery anode: high capacity, low redox potential, dendrite-free deposition, and earth-abundant resources. —Hyun Deog Yoo, first author.
