PASSIVATED CURRENT COLLECTOR FOR A BATTERY CELL

A passivated current collector for a battery cell is provided. A battery cell can include a first electrode that can include a first region that is coated with an active material and a second region that lacks a coating of the active material. The battery cell can include a first terminal that can be in electrical contact with the first electrode via a first current collector that can be electrically coupled to the second region of the first electrode and the first terminal. The first current collector can include a passivated portion exposed to an electrolyte in contact with the first electrode.
