Abstract

A method for the manufacturing of electrodes with at least one porous surfacial layer comprising anisotropic electrochemically active particles. It also relates to electrodes made using such a method. The method comprises the following steps: (a) coupling of paramagnetic nanoparticles to said active particles for the generation of composites; (b) preparation of a slurry of said composites, including a solvent mixed with a binder able to release a volatile component; (c) application of said slurry to a substrate to form a film; (d) application of a magnetic field to the film and orienting said active particles leading to a substrate in which said active particles are arranged with their shortest axes aligned along a preferred axis parallel to said substrate; (e) during or after application of said magnetic field evaporation of said solvent with solidification of the binder and release of said volatile component under formation of said surfacial layer.
