Abstract

A galvanic element, for example a battery or an accumulator, in particular a lithium-ion cell, includes a negative electrode, a positive electrode, and a separator lying between the negative electrode and the positive electrode. In order to increase the specific capacitance, the negative electrode includes at least one layer system, said layer system including at least two graphene layers and at least one polymer layer. A polymer layer lies between two graphene layers.
