Abstract
(EN)
A pre-charged material comprising silicon-comprising fibres characterised in that two or more of the fibres are bonded together to create both a bonded felt anode structure with or without a current collector and a composite anode structure with a current collector and an electrode structure. The structure overcomes problems associated with charge/discharge capacity loss.
(FR)
L'invention concerne un matériau préchargé comprenant des fibres contenant du silicium, caractérisé en ce qu'au moins deux fibres sont reliées ensemble de manière à créer une structure d'anode en feutre non tissé sans ou avec un collecteur de courant et une structure d'anode composite avec un collecteur de courant et une structure d'électrode. La structure permet d'éviter les problèmes liés à une perte de capacité de charge/de décharge.
