The invention relates to a cathode for an electrochemical accumulator including a current collector, an interfacing layer, the interfacing layer being coated on the current collector, and an electrode, the electrode being formed by deposition, in particular by coating, of a first composition on the interfacing layer, the first composition having a hydrogen potential greater than or equal to 10, preferably greater than or equal to 12, the hydrogen potential being measured at a temperature of 25° C.

Cathode for electrochemical accumulator and associated accumulator, energy storage device and manufacturing method

A current collector of an electrochemical actuator is proposed, the current collector being coated with an interfacing layer, the interfacing layer being formed by coating on the current collector with a composition, the composition being formed by particles, at least 50% of the particles having a mean diameter by volume of less than or equal to 10 micrometers.

Current collector, associated set and storing device

The present invention relates to composite material comprising a matrix and a metallic layer located at at least one surface of said composite material, said matrix comprising at least one polymer and a first population of particles of at least one electronically conducting metal, said layer comprising a second population of particles of at least one electronically conducting metal, a method for preparing such composite material and applications thereof.

Cathode of accumulator, associated accumulator and battery

The present invention relates to a current collector comprising: a substrate, the substrate being made of a first material, the first material comprising a polymer, and a grid in contact with the substrate, the grid being made of a second material, the second material comprising metal particles.

Grid current collector and associated devices and methods

A composition for a protection layer for a thermal transfer ribbon which is free of solvents and which contains an acrylate oligomer or polymer having a functionality lower than or equal to 3, a di- or triacrylate monomer and a slip agent which are UV-crosslinkable in the presence of a photoinitiator, capable of forming, after coating on a backing film and after UV crosslinking, a protection layer having a thickness lower than 1 &#x3bc;m. The layer has a good adhesiveness and a low friction coefficient. The composition can particularly be used for the back () of a thermal transfer ribbon () applied on a surface of the backing film (), the other surface of the film receiving at least one ink layer (), while imparting flexibility and thermal and mechanical resistance to the ribbon ().
