ELECTROCHEMICAL CELLS HAVING SEMI-SOLID ELECTRODES AND METHODS OF MANUFACTURING THE SAME

摘要

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.

主权项

1. An electrochemical cell, comprising:
a positive current collector having a first surface and a second surface; a semi-solid cathode disposed on only the first surface of the positive current collector; a negative current collector having a first surface and a second surface; a semi-solid anode disposed on only the first surface of the negative current collector; and a separator disposed between the first surface of the positive current collector and the first surface of the negative current collector.
