Because of the intermittent nature of most renewable energy, storage solutions play a vital role in the availability of energy throughout the day.
This requires the improvement of existing storage technologies, the development of new more cost-effective and better-performing technologies, and the installation of markets and regulation to stimulate the integration of storage systems in the distribution grids.
In this context, Starz Energies performs research on battery electrode materials based on the extensive technologies in the field of electrochemistry, metals, organic/inorganic materials, etc.
At the Starz Energies battery lab, we work to develop analytical methods and advanced diagnostics that can improve the ability to do research.
Starz Energies has engaged to investigate new and promising materials for future battery chemistries:
Our research focuses on improving battery energy density while ensuring safety, long life, and competitive cost.
In our laboratory we have applied the solid state, sol gel and co-precipitation synthesis methods to fabricate LFP/C, LCO, LMO, and NMC cathodes materials for Lithium-ion batteries (LIBs).
Fig.1 shows the X-ray diffraction (XRD) pattern of LiFePO4/C prepared in Starz Energies lab. The experimental data can be indexed to single olivine phase with a Pnma space group, without signs and traces of impurities (JCPDS81-1173).
In nature, LiFePO4 crystallizes in orthorhombic Olivine-type structure (Fig.2), with space group Pnma, and is known as triphylite.
The lattice parameters are a=10.33Å, b=6.01Å, and c=4.69Å; the unit cell volume is V=291.2Å3.
Spinel lithium titanium oxide (Li4Ti5O12, LTO), a high lithium insertion/extraction voltage of approximately 1.55 V (vs. Li/Li+) and excellent cycle stability, has been successfully prepared.
Figures 2a shows the XRD patterns of Li4Ti5O12 powder. All diffraction peaks were in accordance with the standard diffraction pattern of LTO, Powder Diffraction File (PDF) number 049-0226, which can be indexed to a cubic Spinel structure with the space group of Fd-3m.
Figures 2b show the unit cells of Spinel lithium titanium oxide (Li4Ti5O12, LTO), which belong to the Fd-3m space group (No. 227).
