This presentation shows a brief description of the advances of the technologies of lithium in South America and the state of the art of this type of battery at the level of basic research and industrial developments in Argentina and the world. In addition, some results of the development of materials for high performance electrodes for lithium-ion batteries are presented. In our laboratories we focus on the area of lithium-sulfur batteries and the spinels of LiMn2O4, LiMn2-xNixO4, and LiNi0.5Mn1.49Ti0.01O4, which are the most promising systems in this particular field, and on the synthesis and physical and electrochemical characterization of these materials using different techniques such as cyclic voltammetry, charge-discharge cycling, electrochemical impedance spectroscopy, SEM, TEM, XRD, and EDS. The synthesized cathodic materials will be used to develop lithium-ion battery prototypes. With this setup it is now possible to characterize different anodic and cathodic active materials by X-ray spectroscopy techniques such as XANES and EXAFS at different working conditions i.e., different states of charge (SOC) or during a potentiodynamic run, and also under normal operation conditions such as charge-discharge cycles.
