Material and electrochemical characterization of Li-rich NMC cathode materials
Lithium-rich NMC (Ni, Mn, Co) cathode materials are attractive due to their high specific capacity. The charge-discharge profile of lithium-rich cathode materials is different from that of the stoichiometric layered cathode materials such as NMC 111 due to their different lithium intercalation/deintercalation dynamics. Understanding the lithium dynamics with respect to their overall metal composition is critical for its further development. This project will focus on the material and electrochemical characterization of a series of Li-rich cathode materials. This project will take place at materials and device engineering group (MADE) at ETH Zurich.
Material characterization: X-ray diffraction, Scanning electron microscopy
Electrochemical characterization: Galvanostatic charge-discharge cycling, Electrochemical impedance spectroscopy

The goal of this semester project is to compare the charge-discharge profiles of a series of Li-rich cathode materials and understand their intercalation/deintercalation property.
