Abstract: Embodiments described herein relate to electrochemical cells with dendrite prevention mechanisms. In some aspects, an electrochemical cell can include an anode disposed on an anode current collector, a cathode disposed on a cathode current collector, the cathode having a first thickness at a proximal end of the cathode and a second thickness at a distal end of the cathode, the second thickness greater than the first thickness, a first separator disposed on the anode, a second separator disposed on the cathode, an interlayer disposed between the first separator and the second separator, the interlayer including electroactive material and having a proximal end and a distal end, and a power source electrically connected to the proximal end of the cathode and the proximal end of the interlayer, the power source configured to maintain a voltage difference between the cathode and the interlayer below a threshold value.

Abstract: Embodiments described herein relate to electrochemical cell assemblies with structural members for application of compressive force. In some aspects, an electrochemical cell assembly can include a plurality of electrochemical cells arranged in a stack, a first planar sheet in contact with a first side of the stack, a second planar sheet in contact with a second side of the stack, a first structural member in compressive contact with the first planar sheet, and a second structural member in compressive contact with the second planar sheet, wherein the compressive contact between the first structural member and the first planar sheet and the compressive contact between the second structural member and the second planar sheet collectively provide structural rigidity to the electrochemical cell assembly.
