Abstract
Embodiments described herein relate generally to electrochemical cells having semi-solid electrodes that are coated on only one side of a current collector. In some embodiments, an electrochemical cell includes a semi-solid positive electrode coated on only one side of a positive current collector and a semi-solid negative electrode coated on only one side of a negative current collector. A separator is disposed between the semi-solid positive electrode and the semi-solid negative electrode. At least one of the semi-solid positive electrode and the semi-solid negative electrode can have a thickness of at least about 250 μm.
Claims28
A method of manufacturing an electrochemical cell stack, the method comprising:
- coating a first semi-solid cathode onto a first surface of a first positive current collector, the first positive current collector having a second surface, the second surface being uncoated;
- coating a second semi-solid cathode onto a first surface of a second positive current collector, the second positive current collector having a second surface, the second surface being uncoated;
- coupling the second surface of the first positive current collector to the second surface of the second positive current collector.
A method of manufacturing an electrochemical cell stack, the method comprising:
- coating a first semi-solid anode onto a first surface of a first negative current collector, the first negative current collector having a second surface, the second surface being uncoated;
- coating a second semi-solid anode onto a first surface of a second negative current collector, the second negative current collector having a second surface, the second surface being uncoated;
- coupling the second surface of the first negative current collector to the second surface of the first negative current collector.
