Capacitor forming method
View Patent ↗The capacitor forming method utilizes a plurality of metal sheet manipulating rollers and a glass supply, which, in combination, make a metal-glass laminate and glass or devitrifying glass dielectric to form a capacitor. Several embodiments of the method manufacture ferroelectric crystal dielectrics by utilizing heat-treatment and annealing to form and devitrify glass while the glass is in a metal-glass spool or flat form.
1. A super capacitor forming method, comprising the steps of:
forming first, second, third and fourth dielectric sheets of viscous glass material, each of the sheets having a first and a second surface;
rolling a first thin metal foil onto the first surface of the first dielectric sheet while the first dielectric sheet has a viscosity of approximately 10,000 poises;
rolling a second thin metal foil onto the first surface of the second dielectric sheet while the second dielectric sheet has a viscosity of approximately 10,000 poises;
rolling a third thin metal foil onto the first surface of the third dielectric sheet while the third dielectric sheet has a viscosity of approximately 10,000 poises;
rolling a fourth thin metal foil onto the first surface of the fourth dielectric sheet while the fourth dielectric sheet has a viscosity of approximately 10,000 poises;
combining the first, the second, the, third, and the fourth dielectric sheets, the first dielectric sheet being on a top layer, the fourth dielectric sheet being on a bottom layer;
rolling a fifth thin metal foil onto the second surface of the fourth dielectric sheet while the fourth dielectric sheet has a viscosity of approximately 10,000 poises, thereby forming a five metal foil-glass laminate;
cooling the dielectric sheets concurrently with the thin metal foil rolling steps;
heat-soaking the viscous glass material portion of the five metal foil-glass laminate; and
annealing the five metal foil-glass laminate, whereby said super capacitor is formed in a flat configuration.
2. The capacitor forming method according to claim 1 , further comprising step of infusing cooling air directly into the glass dielectric sheets during said forming process of the glass dielectric sheets.
3. The capacitor forming method according to claim 1 , wherein a roll dispensing rate of said fifth metal foil is approximately one foot per second.
4. The capacitor forming method according to claim 1 , further comprising the step of subjecting said five metal foil-glass laminate to forced air cooling before initiating said five metal foil-glass annealing process.
