1. A battery cell, comprising:

  • a cathode active material;

    a cathode current collector;

    an electrolyte;

    an anode active material; and

    an anode current collector;

    wherein the cathode current collector comprises a layer of polyamide covered on each side by only one graphene monolayer, wherein the only one graphene monolayer on each side of the polyamide layer is sandwiched by the polyamide layer and the cathode active material, and wherein the only one graphene monolayer from each side of the polyamide layer is connected with each other at the end of the polyamide layer to form a continuous current collector.
