  • Form factored and flexible ultracapacitors
    Patent number: 8274781
    Abstract: Advanced ultracapacitor construction of irregular shape is provided, having higher utilization of the available energy storage shape in various electronic and electromechanical products over the prior art ultracapacitors. Said irregular shape of ultracapacitor is achieved by using flexible and pliable cell materials in layers, blanked into any desired shape, and stacked. The layers may be also bent to follow any contour. More capacity in given irregular volume is thus accomplished.
