A method for the manufacturing of electrodes with at least one porous surfacial layer comprising anisotropically shaped electrochemically active particles having a longest axis (a) which is at least 1.5 times longer than the shortest axis (c), and having a ratio of the longest axis (a) to a second longest axis (b) which is smaller than 2, comprising at least the following steps: (a) coupling of paramagnetic nanometer-sized particles to the surface of said anisotropically shaped electrochemically active particles for the generation of composites of nanometre-sized particles with anisotropically shaped electrochemically active particles; (b) preparation of a slurry of said composites of nanometre-sized particles with anisotropically shaped electrochemically active particles, said slurry including a solvent mixed with a binder and/or or a liquid binder able to release a volatile or elutable component; (c) application of said slurry to a planar substrate to form a film having a thickness in the range of 1-1000 micro-meter; (d) application of a magnetic field at least to the film and orienting said anisotropically shaped electrochemically active particles leading to a slurry-coated substrate in which said anisotropically shaped electrochemically active particles are arranged in that their shortest axes are, at least region-wise, essentially aligned along a common preferred axis oriented parallel to said substrate in said region; (e) either during or after application of said magnetic field evaporation of said solvent with solidification of the binder and/or solidification of the binder and release of said volatile component and/or solidification of the binder and subsequent elution of the elutable component, under formation of said surfacial layer with a solid volume fraction below 100%. (a) coupling of paramagnetic nanometer-sized particles to the surface of said anisotropically shaped electrochemically active particles for the generation of composites of nanometre-sized particles with anisotropically shaped electrochemically active particles; (b) preparation of a slurry of said composites of nanometre-sized particles with anisotropically shaped electrochemically active particles, said slurry including a solvent mixed with a binder and/or or a liquid binder able to release a volatile or elutable component; (c) application of said slurry to a planar substrate to form a film having a thickness in the range of 1-1000 micro-meter; (d) application of a magnetic field at least to the film and orienting said anisotropically shaped electrochemically active particles leading to a slurry-coated substrate in which said anisotropically shaped electrochemically active particles are arranged in that their shortest axes are, at least region-wise, essentially aligned along a common preferred axis oriented parallel to said substrate in said region; (e) either during or after application of said magnetic field evaporation of said solvent with solidification of the binder and/or solidification of the binder and release of said volatile component and/or solidification of the binder and subsequent elution of the elutable component, under formation of said surfacial layer with a solid volume fraction below 100%.
