1. An electrode comprising an active component directly bonded to a current collector, wherein the active component comprises silicon-comprising fibres arranged in a felt-like structure in which the fibres cross over to provide multiple intersections, such that the fibres contact others of the fibres a plurality of times along their lengths and the direct bonding is via a compound formed from the active component and the current collector at contacting surfaces of the active component and the current collector.
