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: A power wafer includes an enclosure that houses an energy plate such as a battery, capacitor, super-capacitor or other type of electrical energy storage device. A power wafer uses conductive infusions to make internal electrical connections. In some embodiments, the power wafer has an enclosure formed of a top structure and a bottom structure, which are configured to snap together. The bottom structure has an energy plate void and conductive infusion voids. In some embodiments, the infusions have carbon nanotubes that are magnetically aligned to increase the electrical and thermal conductivity of the infusions. In certain embodiments, the enclosure is configured to hold multiple energy plates in parallel and/or in series to increase the amperage and/or voltage of the power wafer. When the plates are stacked in parallel, an insulating barrier is placed between the plates.

Abstract: A secondary battery, including an electrode assembly having a positive sheet and a negative sheet and a separator is interposed therebetween; a tape to wrap an outer surface of the electrode assembly; and a case to receive the electrode assembly. After a remainder of the tape is formed to extend beyond a lower surface of the electrode assembly and joined by a press, the remainder is positioned between a bottom surface of the case and the lower surface of the electrode assembly. According to the embodiment of the present invention, since a junction portion of the tape extended to the outside of the lower surface of the electrode assembly is bent and inserted into the case, a shock-absorbing action is provided to reduce an external shock applied to the secondary battery. Further, an additional tape process can be omitted to simplify a manufacturing process of the secondary battery.
