    Abstract: The described embodiments relate to methods and apparatus for improving pick and place operations. Pick and place operations involving the movement of flexible substrates can be improved by cooling a flexible substrate below a threshold temperature at which the flexible substrate transitions from a flexible state to a rigid state. Once in the rigid state, the flexible substrate can be handled and maneuvered by pick and place operations for a period of time with a limited risk of the flexible substrate wrinkling and tearing. In some embodiments, the flexible substrate is a thin polymeric substrate used to separate oppositely charged battery cells within a battery assembly.

    Abstract: The disclosed embodiments relate to the manufacture of a battery cell. The battery cell includes a first set of layers including a cathode with an active coating, a separator, and an anode with an active coating. The separator may include a ceramic coating and a binder coating over the ceramic coating. During manufacturing of the battery cell, the layers are stacked, and the binder coating is used to laminate the first set of layers within the first sub-cell by applying at least one of pressure and temperature to the first set of layers. One or more fiducials are also disposed on each electrode from a set of electrodes for the battery cell and/or a fixture for the electrodes. The one or more fiducials may be used to align the electrodes during stacking of the set of electrodes.

    Abstract: Battery housings and batteries are presented for accommodating swelling of an electrode assembly. In one aspect, a battery includes an electrode assembly that includes a cathode and an anode. The battery also includes a receptacle that includes at least one feedthrough disposed through one or more sides of the receptacle. A lid is sealed to the receptacle. The receptacle, the at least one feedthrough, and the lid form a sealed volume in which the electrode assembly and an electrolyte are disposed. The lid is configured to displace from a first position to a second position in response to a swelling of the electrode assembly within the sealed volume. The receptacle is configured to strain less than the lid during the swelling of the electrode assembly. The second position of the lid may correspond to an expanded volume of the electrode assembly that is 15% greater than an initial volume.
