    Abstract: An electrochemical cell comprising a first electrode separated from a second electrode by a shutdown separator. The first electrode can comprise a first current collector substrate having a first active material composite layered thereon. The second electrode can comprise a second current collector substrate parallel to the first current collector substrate. The second current collector substrate can have a second active material composite layered thereon. The first current collector substrate can have a first current collector tab extending from the first current collector substrate at a position along an axis parallel to a plane defined by the first current collector substrate. The second current collector substrate can have a second current collector tab extending from the second current collector substrate at a same position along the axis as the first current collector tab. A battery including the electrochemical cell and methods for manufacturing the battery are also described.

    Abstract: An electrochemical cell includes a positive electrode including a first current collector, one or more first tabs, and a first active material. A negative electrode includes a second current collector, one or more second tabs, and a second active material. A separator is disposed between the positive electrode and the negative electrode. A resistive coating is configured to at least partially coat one or both of the first current collector, the second current collector, the one or more first tabs, and the one or more second tabs.
