Abstract: Methods for manufacturing multi-functional electrode (MFE) devices for fast-charging of energy-storage devices are provided. The method includes assembling first MFE structure for forming a suitable electrochemical half-couple, the first MFE structure having a first fast-charging component (FCC) and a first MFE assembly and a counter-electrode structure for forming a complementary electrochemical half-couple and supplying an internal voltage controller (IVC) for applying a bias potential to the first MFE structure and/or the counter-electrode structure, the bias potential is set in accordance with the first MFE structure and said counter-electrode structure. The IVC is configured to regulate an intra-electrode potential gradient between the first FCC and the first MFE assembly to control a charge rate from the first FCC to the first MFE assembly.
