Embodiments described herein relate to electrochemical cells with dendrite prevention mechanisms, and methods of producing and operating the same. In some aspects, an electrochemical cell can include an anode and a cathode material disposed on a cathode current collector, the cathode material and the cathode current collector forming a cathode. The electrochemical cell further includes a first separator disposed on the anode, a second separator disposed on the cathode, and an interlayer disposed between the first separator and the second separator, the interlayer including electroactive material, the interlayer including a source of lithium ions, the lithium ions configured to migrate toward the anode upon a voltage difference between the interlayer and the anode exceeding a threshold value. In some embodiments, the anode can include an anode material disposed on an anode current collector. In some embodiments, the anode material can include graphite, silicon, and/or hard carbon.
