Abstract

A lithium cell is described having a cathode structure made of a base material which conducts electrons and Li ions. The cathode structure includes a continuous substrate, which provides a continuous base area, starting from which a plurality of crosspieces extends. The crosspieces provide crosspiece surfaces, starting from which carrier structures extend. The carrier structures provide carrier surfaces on which active material is distributed. In addition, an accumulator is also described in which a plurality of lithium cells is stacked. A method for producing a lithium cell is also described.
