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.

Abstract: A device for producing a releasable clearance-free position of a rolling bearing, having a rolling bearing which has an outer ring, an inner ring mounted on a shaft and a plurality of rolling elements arranged between the inner ring and the outer ring, and having a tensioning device mounted on the circumference of the rolling bearing outer ring for generating a radial preload which is uniform over the outer circumference of the rolling bearing outer ring between the tensioning device and the rolling bearing outer ring, wherein the tensioning device has an axially adjustable tensioning element which can be brought into a first alignment in which the rolling bearing has play, and which can be brought into a second alignment in which the rolling bearing is free of play. A corresponding method is also described.

Abstract: Disclosed are apparatuses and methods for forming films having uniform thicknesses across the entire width of the film. The films are also disclosed. The apparatus for forming the film includes a first nip roller and a second nip roller, each of the first nip roller and the second nip roller being configured to compress the powder as it passes between the first nip roller and the second nip roller and thereby form the film, whereby in the absence of a force counteracting the pressure of the passage of the powder between the first nip roller and the second nip roller the first nip roller is deflected to a greater degree than the second nip roller. Furthermore, the first nip roller and the second nip roller are each associated with one or more eccentric bearings that rotate to apply force vectors to the first nip roller and the second nip roller.
