V2O5 XEROGEL LITHIUM-POLYMER ELECTROLYTE BATTERIES

In this report are described the fabrication and the characterization of a Lithium-metal, polymer electrolyte battery using a V2O5 xerogel c athode. The system operates at moderate temperatures (80-100 degrees C ). The electrochemical characterization of separate components as well as of small scale devices is also reported. The work is focused on th e determination of important 'application' properties of the polymer e lectrolyte, i.e., the properties of the polymer electrolyte in real sy stems and true operating conditions. The work was developed within the ALPE (Advanced Lithium Polymer Electrolyte) project, an Italian proje ct devoted to the realization of lithium polymer batteries for electri c vehicle applications, in collaboration with the Corrosion Research C enter of the University of Minnesota.
