Development and Evaluation of Vanadium Pentoxide in a Composite Cathode

Leland Manhart

Professor William H. Smyrl

Supported by ARPA



This work focuses on using vanadium pentoxide xerogel (XRG) as active material in a composite cathode for a high energy rechargeable lithium battery. Vanadium pentoxide material offers a high specific capacity (560 Ah/kg) and a high energy density (1200 Wh/kg). These capacity and energy densities were obtained from thin film technology. From this the goal of this project is to evaluate the performance of the XRG composite cathode in coin cell technology. Numerous parameters are being studied to optimize the performance of these cells, these include: cathode process, cathode formulation, electrode morphology, cell assembling and electrolyte. Structural characterization of the material has also been done by XRD (x-ray diffraction) and by SEM.
