Advanced Materials and Electrochemistry for Energy Laboratory


Advanced Materials and Electrochemistry for Energy (AMEE) Laboratory at Oklahoma State University investigates performance of materials for electrochemical energy storage and conversion systems.

Li-ion Batteries

Lithium (Li)-ion batteries dominates the current landscape of energy storage for portable electronics. However, more demanding applications such as electrical vehicles requires fast charging of Li-ion batteries, which causes performance loss .

Na-ion & K-ion Batteries

Replacing Li with more abundant Sodium (Na) or Potassium (K) can reduce cost of batteries for stationary applications. Na-ion and K-ion batteries requires new material chemistries because they are larger and heavier compared to Li ions.

Li-Oxygen Batteries

Lithium Oxygen batteries have higher theoretical capacity compared to Li-ion batteries. However,  irreversible parasitic reactions and poor understanding of surface chemistries prevents reaching its theoretical capacities.

Solid Electrolytes

Replacing organic liquid electrolytes in  Li-ion batteries with solid electrolytes can prevent batteries catching fire and allow new battery chemistries. However, interfacial instabilities between   electrolyte - electrode is the bottleneck of solid electrolytes.
