Resumen:
The lithium batteries are electrochemical systems based on the use of intercalation compounds supported on porousstructures. Different materials are used as cathodes: for example, mixed oxides of transition metals (LiMO2, where M: Mn, Coand / or Ni), and carbons materials (commercial carbon and Sungite carbon) are used as anodes.The preparation of anodes and cathodes materials are presented. Optical techniques (as DRX, SEM and TEM) are used tocharacterize the prepared material. The electrochemical performance are studied by electrochemical techniques: chargedischargecycles, galvanostatic discharge at different currents and cyclic voltammetry.
