A method is provided for fabricating a component material for a battery cell. The method comprises the steps of: providing a partially-fabricated battery cell, the partially-fabricated battery cell comprising a substrate having a planar deposition surface consisting of a first face of the substrate and a first battery component layer provided on the planar deposition surface, the substrate having a plurality of further surfaces, the planar deposition surface and the plurality of further surfaces defining the body of the substrate therebetween; wherein: the first battery component layer contains charge-carrying metal species and has an exposed surface; one or more electrically conductive or semi-conductive pathways extend through at least a portion of the substrate, each of the one or more pathways connecting the planar deposition surface to one of the plurality of further surfaces; and the partially-fabricated battery cell is held in position within a deposition chamber by a holding structure and each site of connection between one of the one or more pathways and the holding structure is electrically insulating; the method further comprising the step of depositing a second battery component layer on the first battery component layer, wherein the depositing comprises forming a plasma within the deposition chamber.
