摘要：

The development and characterization of a polymeric composite based on non-stoichiometric Li1.03Mn1.97O4 spinet operating at 4 V and poly(3,4-ethylenedioxy)thiophene (pEDOT) are reported. In this composite the pEDOT substitutes the carbon usually mixed with the inorganic oxide-based electrodes to improve their electronic conductivity; the pEDOT thus functions as an electronic conductor and is electroactive in the same potential range of LiMn2O4. Electrochemical data for pure pEDOT and for composites of pEDOT/carbon, conventional Li1.03Mn1.97O4/carbon and polymer Li1.03Mn1.97O4/pEDOT are reported and discussed. (C) 2002 Elsevier Science B.V.
