A BATTERY CELL COMPRISING AN ANODE AND A METHOD FOR MANUFACTURING THEREOF

The invention relates to a battery cell comprising a three-dimensional porous anode and a method of manufacturing of the battery cell with said anode. A build material comprising a carbon based active material is used, the carbon based active material configured to participate in a battery electrode reaction. Furthermore, interconnected filaments of a build material are deposited in a predetermined arrangement in a plurality of stacked layers, wherein the filaments of the consecutive layers are connected to one another to obtain a porous anode structure with intra-structure pores formed between filaments.
