NM01.27.04: Optimizing Battery Components Using Si - Ge

    After a short break in between symposium sessions, I got the chance to touch up on my knowledge of the recent developments in electronics at the NM01.27: 2D Materials for Energy Applications. There, I attended the presentation by PhD. student Xi Chen from the Laboratoire de Réactivité et Chimie des Solides (LRCS) on “2D Silicon-Germanium-Layered Materials as Anodes for Li-ion Batteries”. And was able to learn the advantages of using germanium (Ge) doped silicon (Si) as battery components.

    Because our world continues to grow more and more dependent on electrical energy, the way we store that energy has become an important matter. With this in mind, the research team sought to optimize modern batteries by integrating both Si and Ge components to increase the battery’s conductivity. By applying this knowledge to rigid 2D arrangements, it is possible to reduce the cost and physical expansion of our electronics. This has a cascade effect which results in an overall increase of our devices’ lifetime.

    Performing their synthesis, they were able to develop a solid mixture of silicon and germanium, called siligane. This chemical product can be generated in three types: a Si-rich group, a Ge-rich group and a medium group. After characterizing the compounds by X-Ray Diffraction, Raman, Infrared spectroscopy and SEM they performed tests on lithium-ion batteries with the different types of siligane as anodes. Since the composition was mainly Si, the price of these new anodes was not drastically increased; but, the presence of the dopant exhibited a significantly high conductivity and capacity which is characteristic of Ge.

My First Symposium of the Meeting, CH01.14.07 Colloidal Nanoparticles and Their Kinetics

    He rushed through the symposium agenda, fully aware that he was late. “There is nothing that can be done about it. Let’s focus on the here and now.” He thought.

    One subject stood out from the rest of the symposiums for that 2:00pm time slot: “CH01.14: Frontiers of In Situ Materials Characterization – From New Instrumentation to Imaging Aided Materials Design II”. He clicked on the link and then entered the meeting in the middle of an ongoing presentation which he waited for it to finish and was able to catch the last presenter before the session was over.

    The presenter: Yugang Sun; the topic: Evolution Kinetics of Colloidal Nanoparticles.


    The presentation moved at a comfortable pace and began with a captivating chemical reaction that showed a change in color. Then the researcher gave the audience some theoretical background regarding the mechanism for the formation of the nanoparticles. These could nucleate either through the classical nucleation mechanism (LSW theory) or through the Finke-Watzky two-step (FW 2) mechanism. But the researcher justified why they believe that the LSW theory took precedence by stating reasons against the FW 2 mechanism.

    After that, the researcher went in-depth with the mathematical derivation of the chemical kinetics, specifying the approximations that were made as well as the special cases considered that resembled their study with silver nanoparticles. The time resolved High Energy X-Ray Diffraction showed a distinct peak as the heating time increased. Because of the different analysis on the density, concentration and temperature, some interesting behaviors were brought to light which allowed Dr. Yugang Sun to predict the volume of their silver nitrate nanoparticles.
