Claims
- 1. A process for making an electrolytic capacitor comprising the steps of:providing a thin metallic powered anode foil and a thin metallic floating anode foil; etching said powered anode foil and said floating anode foil to provide enhanced surface area; forming an oxide layer on said powered anode foil and said floating anode foil; providing a plurality of separators and a thin metallic cathode foil; and rolling said anode foils, said cathode foil and said separators into a substantially cylindrical wound roll such that said floating anode plate is disposed between said cathode plate and said powered anode plate and said separators are disposed therebetween.
- 2. The method of claim 1, further including enclosing the assembly in a housing.
- 3. The method of claim 1, further including the step of impregnating said capacitor with an electrolyte.
- 4. A process for making an electrolytic capacitor comprising the steps of:providing a first thin metallic anodic foil and a second thin metallic anodic foil; etching said first anodic foil and said second anodic foil to provide enhanced surface area; forming an oxide layer on said first anodic foil and said second anodic foil; cutting and removing a powered anode plate from said first anodic foil and cutting and removing a floating anode plate from said second anodic foil; providing a plurality of separators and a cathode plate; and stacking said plates and separators such that said floating anode plate is disposed between said cathode plate and said powered anode plate and said separators are disposed therebetween.
- 5. The method of claim 4, further including enclosing the assembly in a housing.
- 6. The method of claim 4, further including the step of impregnating said capacitor with an electrolyte.
