Abstract: A system and methods for manufacturing a dry electrode for an energy storage device are disclosed. The system includes a first dry electrode material delivery system configured to deliver a dry electrode material, a first calendering roll, a second calendering roll, and a controller. The second calendering roll is configured to form a first nip between the first calendering roll and the second calendering roll. The first nip is configured to receive the dry electrode material from the first dry electrode material delivery system, and form a dry electrode film from the dry electrode material. The controller is configured to control a rotational velocity of the second calendering roll to be greater than a rotational velocity of the first calendering roll.

Abstract: Systems and methods of providing powder are disclosed. A system includes a powder hopper, one or more sensors, a feeder hopper and a processor in operable communication with the one or more sensors and the feeder hopper. The powder hopper is configured to provide a powder to a pair of rollers. Each of the one or more sensors is configured to determine a characteristic of the powder in the powder hopper. The feeder hopper is configured to provide the powder to the powder hopper. The processor is configured to cause the feeder hopper to provide the powder to the powder hopper in response to the characteristic of the powder in the powder hopper being less than a threshold.
