PREPARATION, CHARACTERIZATION AND ELECTROCHEMICAL LITHIUM INSERTION INTO THE NEW ORGANIC-INORGANIC POLY(3,4-ETHYLENE DIOXYTHIOPHENE)/V_2O_5 HYBRID

並列摘要


Poly(3,4-ethylene dioxythiophene) (PEDOT) has been inserted between the layers of crystalline V_2O_5 via the in situ polymerization of EDOT within the framework of the oxyde. The insertion increases the bidimensionality of the V_2O_5 host by the layer separation but results in a random layer stacking structure, leading to broadening of the energy state distribution. According to electrochemical measurements, the hybrids showed reversible specific capacities up to ~330mAh/g at 15mA/g between 2 and 4.4V vs. Li^+/Li.
