Electrochemical device or photo-electrochemical device comprising an electrolyte containing a bistriflimide anion, hereafter named as TFSI&#x2014;, at least two electrodes, each of these electrodes being in contact with a current collector comprising a metal support characterized in that at least one electrode has a current collector the metal support of which comprises an electro-active surface which is functionalized with linear or branched fluorinated carbon chains, such as perfluoroalkyl chains, in the form of a molecular layer which improves the corrosion resistance of said functionalized surface compared to a non-functionalized surface, wherein not impairing the passage of electrons between said electrode and its current collector, the functionalized surface being at the interface between said electrode and its current collector.

Electrochemical devices with current collector having an increased resistance to corrosion

A microstructured substrate includes a plurality of at least one elementary microstructure. An electrical storage device, and more particularly an all-solid-state battery, can include the microstructured substrate.

Microstructured substrate

The invention relates to compounds comprising a redox group, to the use thereof as an additive to an electrolyte composition, to an electrolyte composition including such an additive, and to electrochemical systems including such an electrolyte composition, in particular lithium or sodium batteries and supercapacitors having a double electric layer.
