Textile electrode and accumulator containing such an electrode

摘要

The invention relates to an electrode comprising (a) an electron collector containing one or more transition metals from the groups 4 to 12 of the Periodic Classification of the Elements, and (b) a material that is electrochemically active, present on the surface of the electron collector in the form of a nano-structured conversion layer containing nano-particles or agglomerates of said nano-particles, wherein the nano-particles have a mean diameter of between 1 and 1000 nm, preferably between 10 and 300 nm, wherein said electrochemically active material contains at least one compound of the transition metal or transition metals present in the electron collector, characterized by the fact that the electrode is a textile formed by metallic wires or fibers. The invention also relates to a half-accumulator and an accumulator containing such a textile electrode.
