High temperature energy storage device
Disclosed herein is a method for fabricating an ultracapacitor, the method comprising disposing an energy storage cell comprising energy storage media within a housing; and constructing the ultracapacitor to operate within a temperature range between about 80 degrees Celsius to about 210 degrees Celsius.
1. A method for fabricating an ultracapacitor, the method comprising:
disposing an energy storage cell comprising energy storage media within a housing; and
constructing the ultracapacitor to operate within a temperature range between about 80 degrees Celsius to about 210 degrees Celsius;
wherein the constructing comprises fabricating at least one of a cap and a body for the housing;
wherein the fabricating comprises disposing a seal comprising an insulator and an electrode insulated from the housing into the housing; and
wherein disposing the seal comprises disposing a hemispheric seal.
2. The method as in claim 1 , wherein the constructing comprises selecting an interior facing material for the housing that exhibits low chemical reactivity with an electrolyte.
3. The method as in claim 2 , further comprising including the interior facing material in substantial portions of the interior of the housing.
4. The method as in claim 2 , wherein the constructing comprises selecting at least one of aluminum, polytetrafluoroethylene (PTFE), perfluoroalkoxy (PFA), fluorinated ethylene propylene (FEP), ethylene tetrafluoroethylene (ETFE), and a ceramic material as the interior facing material.
5. The method as in claim 1 , wherein the constructing comprises forming the housing from a multilayer material.
6. The method as in claim 5 , wherein the forming the housing from a multilayer
material comprises disposing a weldable material on an exterior of the housing.
7. The method as in claim 1 , wherein the constructing comprises disposing a fill port in the housing.
8. The method as in claim 1 , wherein disposing the seal comprises disposing a glass-to-metal seal.
9. The method as in claim 8 , wherein disposing the glass-to-metal seal comprises welding the glass-to-metal seal to an outer surface of the housing.
10. The method as in claim 1 , further comprising fabricating the energy storage cell.
11. The method as in claim 10 , wherein fabricating the energy storage cell comprises obtaining an electrode by joining energy storage media with a current collector.
12. The method as in claim 11 , wherein obtaining the electrode comprises joining a plurality of electrode elements fabricated from joining energy storage media with a current collector.
13. The method as in claim 12 , wherein joining the plurality of electrode elements comprises ultrasonically welding a joining element to the current collector of one electrode element and to the current collector of another electrode element.
14. The method as in claim 10 , wherein fabricating the energy storage cell further comprises joining at least one lead to an electrode.
15. The method as in claim 14 , wherein joining at least one lead to the electrode comprises placing at least one reference mark onto the electrode.
16. The method as in claim 14 , wherein joining at least one lead to the electrode comprises locating each lead at a respective reference mark.
17. The method as in claim 14 , wherein joining at least one lead comprises clearing energy storage media from the current collector.
