Abstract: Embodiments described herein relate to electrochemical cells and multicells. A multicell can include a cell packaging that includes two or more electrochemical cells connected in series internal to the cell packaging. In some aspects, an apparatus includes a plurality of electrochemical cell stacks each including a plurality of electrochemical cells connected in series, a first electrically conductive plate including a first section and a second section, and a second electrically conductive plate. The first section of the first electrically conductive plate is in contact with a first terminal end of a first electrochemical cell stack from the plurality of electrochemical cell stacks. The second section of the first electrically conductive plate is in contact with a first terminal end of a second electrochemical cell stack from the plurality of electrochemical cell stacks.

Abstract: In some aspects, a method of monitoring health of an electrochemical cell can include measuring a first anode voltage at a first anode tab from the plurality of anode tabs and a second anode voltage at a second anode tab from the plurality of anode tabs; measuring a first cathode voltage at a first cathode tab from the plurality of cathode tabs and a second cathode voltage at a second cathode tab from the plurality of cathode tabs; and calculating a first sense voltage, the first sense voltage being a difference between the first cathode voltage and the first anode voltage. In some embodiments, a second sense voltage can be calculated, the second sense voltage being a difference between the second cathode voltage and the second anode voltage. In some embodiments, a difference between the first sense voltage and the second sense voltage can be calculated.

Abstract: The embodiments described herein involve electrochemical cells that have a heating element integrated into the electrochemical cell. In some aspects, an electrochemical cell comprises an anode current collector, an anode material disposed on the anode current collector, a cathode current collector, a cathode material disposed on a first side of the cathode current collector, a separator disposed between the anode material and the cathode material, and a heating element disposed on a second side of the cathode current collector, the second side opposite the first side. The heating element may include an electrically conductive material and a conductive material and disposed in an insulative material.
