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.
Claims24
An electrochemical cell stack, comprising:
- a first current collector having a first surface, a second surface, and a first tab extending from the first current collector, the first surface of the first current collector having a semi-solid cathode material disposed thereon;
- and
- a second current collector having a first surface, a second surface, and a second tab extending from the second current collector, the first surface of the second current collector having the semi-solid cathode material disposed thereon,
- the first tab and the second tab coupled together in a positive bail, the positive bail configured to be coupled to a positive lead.
An electrochemical cell stack, comprising:
- a first current collector having a first surface, a second surface, and a first tab extending from the first current collector, the first surface of the first current collector having a semi-solid anode material disposed thereon;
- and
- a second current collector having a first surface, a second surface, and a second tab extending from the second current collector, the first surface of the second current collector having the semi-solid anode material disposed thereon,
