Abstract: Systems, devices, and methods described herein relate to electrolyte formulations and the incorporation thereof into batteries. In some aspects, an electrolyte composition can comprise between about 10 wt % and about 42 wt % of an electrolyte solvent, between about 13 wt % and about 59 wt % of a fluoroether. In some embodiments, the electrolyte solvent can make up between about 26 wt % and about 39 wt % of the composition. In some embodiments, the fluoroether can make up between about 18 wt % and about 36 wt % of the composition. In some embodiments, the composition can include between about 0.5 wt % and about 1.5 wt % of a first additive. In some embodiments, the composition can include between about 0.5 wt % and about 5 wt % of a second additive.

Abstract: An electrochemical cell system includes a first electrochemical cell including a first anode current collector, a first anode, a first cathode current collector, a first cathode, and a first separator. The first cathode has a first composition such that the first electrochemical cell has a first energy density, and a first power density at a predetermined temperature. A second electrochemical cell includes a second anode, a second cathode current collector, a second cathode, and a second separator. The second cathode has a second composition different from the first composition such that the second electrochemical cell has a second energy density that is less than the first energy density, and a second power density at the predetermined temperature that is greater than the first power density. The first electrochemical cell may include a first electrolyte different from a second electrolyte of the second electrochemical cell.

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.
