1. An electrochemical cell system, comprising:
a first anode current collector and a second anode current collector;
a first anode and a second anode, the first anode disposed on the first anode current collector and the second anode disposed on the second anode current collector;
a cathode current collector;
a first semi-solid cathode and a second semi-solid cathode, at least one of the first semi-solid cathode and the second semi-solid cathode disposed on the cathode current collector; and
a first separator and a second separator, the first separator disposed between the first anode and the first semi-solid cathode, the second separator disposed between the second anode and the second semi-solid cathode,
wherein the first anode has a thickness greater than a thickness of the second anode by a factor of at least about 1.5, and/or
wherein the first semi-solid cathode has a thickness greater than a thickness of the second semi-solid cathode by a factor of at least about 1.5.
 
11. An electrochemical cell system, comprising:
a first current collector;
a first electrode material disposed on a first side of the first current collector;
a second electrode material disposed on a second side of the first current collector, the second side of the first current collector opposite the first side;
a third electrode material disposed on a second current collector;
a fourth electrode material disposed on a third current collector;
a first separator disposed between the first electrode material and the third electrode material to form a first electrochemical cell; and
a second separator disposed between the second electrode material and the fourth electrode material to form a second electrochemical cell, the second electrochemical cell having a thickness greater than a thickness of the first electrochemical cell by a factor of at least about 2.
