HYBRID INSERTION MATERIALS BASED ON VANADYL PHOSPHATE OR VANADIUM PENTOXIDE, AND CONDUCTING POLYMERS

摘要

We describe here the synthesis, characterization and electrochemistry of novel hybrid materials based on vanadyl phosphate and conducting polymers (PAni, PPy). These hybrids were studied as cathodes in Li cells, obtaining good cyclability. We also present further studies on the well-known PAni/V_2O_5 system and analyze its charge loss after 100 successive charge-discharge cycles in Li cells.
