Performance of lithium/V{sub 2}O{sub 5} xerogel coin cells
- Univ. of Minnesota, Minneapolis, MN (United States)
Vanadium pentoxide xerogel (XRG) materials have shown promise for use as cathodes in high energy density batteries. A composite cathode was formed from a mixture of the XRG, carbon, and two binders and studied in a coin cell configuration. The cathode, separator, and lithium anode were stacked in a 2,016 coil cell container, and a liquid electrolyte was used for the investigation. In contrast to thin film configurations where 4 Li{sup +} ions may be inserted per mole of the XRG host, the composite cathode supported the insertion of less than 2 Li{sup +} ions per mole of V{sub 2}O{sub 5} (XRG). It appears that morphology, electronic conductivity, and solid-state diffusivity combined to limit the performance of the cathodes.
