Abstract
An energy storage apparatus for mounting on a printed circuit board using a solder reflow process includes: a sealed housing body including a positive internal contact and a negative internal contact disposed within the body and in electrical communication with respective external contacts. An electric double layer capacitor energy storage cell is disposed within the body Methods of manufacture are disclosed.
Claims14
An energy storage device comprising:
- an energy storage cell comprising:
- an electrolyte;
- a plurality of two-sided electrodes;
- and
- a single separator;
- wherein the plurality of two-sided electrodes and the single separator are immersed in the electrolyte;
- wherein a first electrode of the plurality of electrodes is disposed onto one end of the single separator and wherein a second electrode of the plurality of electrodes is disposed onto an opposing end of the same single separator;
- and continuous strips of the two-sided electrodes are wound into a roll form and separated by the single separator forming a stack comprising a two-sided negative electrode and a two-sided positive electrode;
- wherein the energy storage cell is wound into a roll, and each of the first electrodes and each of the second electrodes contact multiple electrically conductive tabs that extend beyond the energy storage cell and each of the conductive tabs are offset laterally sideways from each other to accommodate for an increasing radius of the energy storage cell in the roll;
- wherein the multiple electrically conductive tabs collectively result in leaders aligned with electrical pads of a housing body;
- and
- wherein the energy storage cell is an ultracapacitor capable of surviving reflow processing.

A method comprising:
- disposing in a body cavity of a body:
- an energy storage cell comprising:
- an electrolyte;
- a plurality of two-sided electrodes;
- and
- a single separator;
- wherein the plurality of two-sided electrodes and the single separator are immersed in the electrolyte;
- wherein a first electrode of the plurality of electrodes is disposed onto one end of the single separator and wherein a second electrode of the plurality of electrodes is disposed onto an opposing end of the same single separator;
