Intercalation-based energy storage systems

Intercalation-based energy storage systems: (a) schematic representation of the operation of lithium-ion batteries; (b) schematic representation of the fragments of crystal structures of tunnel manganese oxides stabilized by potassium, sodium and magnesium; (c) SEM images of the α-MnO2 nanowires; (d) TEM images of the single α-MnO2 nanowire. Structural tunnels are parallel to the nanowire growth direction (c direction); (e) galvanostatic discharge/charge curves of the cells with original and acid-leached α-MnO2 nanowires at the 2nd cycle in the voltage range of 1.5 – 4.2 V at a 0.1C current rate.

The Materials Electrochemistry Laboratory, directed by Anne Stevens Assistant Professor Ekaterina Pomerantseva, works on the development and characterization of novel nanostructured materials, systems and architectures for batteries, supercapacitors and fuel cells in order to understand electrochemical energy storage and conversion at the nanoscale. The lab’s research has two main goals: the development of new nanomaterials, architectures and systems that will address fundamental electrochemical issues; and by answering fundamental questions, will tackle practical challenges and aid in the development of new nanostructured electrochemical systems for efficient superior next-generation energy storage technology.
