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.
