Clarifying the Working Principle of a High-Capacity Battery Electrode

Molybdenum disulfide is a promising electrode material for high-capacity lithium-ion batteries. However, despite decades of effort and intensive recent interest, its lithiation/delithiation reaction mechanism is still controversial. At the Advanced Light Source, X-ray spectroscopy clearly revealed the electrochemical reaction mechanism, facilitating the further development of these high-performance electrodes. This work involved staff from the Energy Storage and Distributed Resources Division and the Materials Sciences Division, as well as the ALS. More>
