| Abstract Scope |
Today, with the development of renewable energies as well as the electrification of vehicles, the energy storage market continues to grow up. The all-solid-state Li-ion batteries are promising candidates for the next generation of batteries allowing to increase densities and to improve safety and recycling. In this work, the focus is on the new type diffusion-dependent cathodes of 100% active material (TiS2 in this case), enabling a significant increase in energy density and volumetric capacity, which is different of the conventional composite cathode. Here, sealed-tube synthesis was carried out that is shown to be purer than the commercial one (XPS). The synthesis is followed by high-energy mechanical milling to modify the TiS2 structure and morphology (XRD, TEM, SEM…). These modifications are designed to improve the Li diffusion and the electrochemical performances of TiS2. Then, cycling tests were performed to validate the electrochemical improvements envisaged. |
