NEGATIVE ELECTRODES FOR USE IN BATTERIES OPERATING ACCORDING TO THE PRINCIPLE OF ION INSERTION AND DE-INSERTION OR ALLOY FORMATION AND ACCUMULATOR COMPRISING SUCH AN ELECTRODE |
| abstract |
The invention relates to a negative electrode for a battery operating according to the principle of ionic insertion and deinsertion and / or according to the principle of formation of an alloy and of de-alloying, said negative electrode comprising: a first layer (3) comprising an active material deposited, via one of its faces, on a first face of a current collector (5); a second layer (7) comprising an active material deposited, via one of its faces, on a second face of a current collector (5), said first face being opposite to said second face; characterized in that the current collector (5) is provided with through holes (6) connecting the first layer to the second layer and in that the first layer is coated with a layer composed of a metal (1), of which the corresponding cations are those involved in the process of ionic insertion or deinsertion and / or in the process of alloy formation and desalloying in the active material of the first layer and of the second layer. |
