Ultracapacitor with a Molecular Sieve Material

Abstract

An ultracapacitor with a molecular sieve material is provided. The ultracapacitor contains a first electrode that includes a first current collector electrically coupled to a first carbonaceous coating, a second electrode that includes a second current collector electrically coupled to a second carbonaceous coating, a separator positioned between the first electrode and the second electrode, and a nonaqueous electrolyte in ionic contact with the first electrode and the second electrode. The ultracapacitor includes a molecular sieve material including a metal aluminosilicate and a binder. The ultracapacitor also includes a housing within which the first electrode, the second electrode, the separator, the nonaqueous electrolyte, and the molecular sieve material are retained.
