Abstract: There is provided a method for producing an anode for lithium batteries. The method comprises: providing a current collector, forming a layer of protective material thereon, depositing a lithiophilic material on the layer of protective material, and depositing a molten lithium material on the layer of lithiophilic material. The lithiophilic material and the molten lithium material subsequently react to form the anode active material. The current collector and/or at least one other layer of the anode may comprise a continuous 3D structure on a surface thereof. The protective material deposited on the current collector constitutes a barrier between the current collector and lithium in the anode active material, therefore formation of cracks in the current collector is avoided.
