  • Sandwich panels with battery cores
    Patent number: 10439248
    Abstract: Systems and methods are disclosed for enhancing the construction and application of batteries by providing a battery system comprising at least one electrochemical panel with at least one electrochemical cell disposed therein, which is configured to enable multi-purpose functionality and applicability of the battery system. Embodiments provide for electrodes and/or current collectors of each electrochemical cell that are transversely orientated with respect to each face of an electrochemical panel. Some embodiments provide for a separator pouch disposed about at least one electrode and/or current collector to electrically insulate the electrode and/or current collector from a structure component of the device. Each electrochemical panel is configured to enable electrical communication with another electrochemical panel and/or an ancillary electric circuit. Each electrochemical panel is configured enable utilization thereof as a structural component of an ancillary structure.

  • Energy absorbing stitch ripping composite tubes containing collapsible cells
    Patent number: 8828513
    Abstract: An energy absorbing system has an inner tube and an outer tube that are stitched together. The inner tube contains a set of fibers oriented in a first direction and the outer tube has a second set of fibers oriented in a direction different from the first direction. Preferably these orientations are equal and opposite to each other. The inner tube may be hollow, but preferably has a cellular core. The outer tube may be spaced apart from the inner tube to create an annular cavity that is filled with a cellular material.
