Electrochemical conditioning of vanadium(V) pentoxide xerogel films (original) (raw)
1999, Electrochemistry Communications
The electrochemical behavior of layered vanadium(V) pentoxide xerogel films has been studied, focusing on the lithium intercalation and reorganization effects accompanying the electrode conditioning process. The films at the initial condition consist of electrochemically heterogeneous regions, which collapse into a uniform band structure as the lithium ions are inserted into the interlamellar space. At the saturation point, a single broad intervalence-transfer band is observed in the visible-near infrared region, and the electrochemical behavior becomes independent of the diffusion process.
