Abstract (en)
[origin: WO2020178509A1] The present invention relates to an electrode for a rechargeable energy storage device, comprising a plurality of inner layers interposed between two outer layers, said inner layers comprising a plurality of electrode-material ME layers composed of at least one active electrode material and a plurality of porous current-collector CC layers composed of one or more electrically conductive materials whose electronic conductivity is higher than or equal to 102 S.cm-1, said electrode-material ME and current-collector CC layers alternating, characterized in that said outer layers are not formed of said porous current-collector CC layers, and in that said electrode has a total thickness ranging from strictly more than 4 mm, preferably ranging from strictly more than 4 mm to 10 mm, in particular ranging from strictly more than 4 mm to 8 mm.
