Preparation, Characterization and Electrochemical Lithium Insertion Into the New Organic–Inorganic Poly(3,4-Ethylene Dioxythiophene)/V2O5Hybrid

[摘要] Poly(3,4-ethylene dioxythiophene) (PEDOT) has been inserted between the layers of crystallineV2O5via the in situpolymerization of EDOT within the framework of the oxyde. The insertion increases the bidimensionality of theV2O5host 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.
