Special Issue Information

Dear Colleagues,

The success of the energy transition will depend on our capacity to produce, transport, consume, and store energy reliably on a large scale and at a low cost. Electrode materials play an important role in the development of renewable energies. Rechargeable batteries are the most appropriate and promising systems. Nowadays, Li-ion batteries (LIBs) dominate the global market for energy storage devices and are used in a variety of applications from portable electronic devices to electrical grid storage and electric vehicles. However, its specific capacity and energy density seem to reach their limits and will be insufficient for the long-term needs of our society. New insertion or conversion materials for electrodes need to be synthesized in order to provide high energy or high power, sufficient autonomy, and low aging.

The choice of electrode materials determines the electrochemical performances of LIBs. However, the synthesis methods are crucial for the properties. Decreasing the particle size and controlling their morphology can improve the electrochemical properties. The substitution of cations by other ions or defects plays a role in electrochemical performances (working potential, electronic and ionic conductivity, and, consequently, energy density). The present Special Issue is focused on electrode materials preparation and characterization for rechargeable batteries (including lithium-ion, metal-ion and all-solid-state batteries) but can be extended to supercapacitor electrodes.

This Special Issue is the continuation of a very successful previous Special Issue with the same focus. We kindly invite you to submit a manuscript for this Special Issue “Electrode Materials: Fabrication, Properties and Applications, Volume II”. Full papers, communications, and reviews are all welcome.

Using Si as anode materials for Li-ion batteries remain challenging due to its morphological evolution and SEI modification upon cycling. The present work aims at developing a composite consisting of carbon-coated Si nanoparticles (Si@C NPs) intimately embedded in a three-dimensional (3D) graphene hydrogel (GHG) architecture to stabilize Si inside LiB electrodes. Instead of simply mixing both components, the novelty of the synthesis procedure lies in the in situ hydrothermal process, which was shown to successfully yield graphene oxide reduction, 3D graphene assembly production, and homogeneous distribution of Si@C NPs in the GHG matrix. Electrochemical characterizations in half-cells, on electrodes not containing additional conductive additive, revealed the importance of the protective C shell to achieve high specific capacity (up to 2200 mAh.g−1), along with good stability (200 cycles with an average Ceff > 99%). These performances are far superior to that of electrodes made with non-C-coated Si NPs or prepared by mixing both components. These observations highlight the synergetic effects of C shell on Si NPs, and of the single-step in situ preparation that enables the yield of a Si@C-GHG hybrid composite with physicochemical, structural, and morphological properties promoting sample conductivity and Li-ion diffusion pathways.

Carbon coatings can help to stabilize the electrochemical performance of high-energy anodes using silicon nanoparticles as the active material. In this work, the comparison of the behavior and chemical composition of the Solid Electrolyte Interphase (SEI) was carried out between Si nanoparticles and carbon-coated Si nanoparticles (Si@C). A combination of two complementary analytical techniques, Electrochemical Impedance Spectroscopy and X-ray Photoelectron Spectroscopy (XPS), was used to determine the intrinsic characteristics of the SEI. It was demonstrated that the SEI on Si particles is more resistive than the SEI on the Si@C particles. XPS demonstrated that the interface on the Si particles contains more oxygen when not covered with carbon, which shows that a protective layer of carbon helps to reduce the number of inorganic components, leading to more resistive SEI. The combination of those two analytical techniques is implemented to highlight the features and evolution of interfaces in different battery technologies. Full article
