Abstract

See full text

A hybrid supercapacitor energy storage device comprises at least one lead electrode, at least one carbon electrode, a separator, a casing, and an acid electrolyte. The lead electrode is enveloped in a common glass mat separator known in the lead-acid battery industry. The carbon electrode comprises a highly conductive current collector which is a sheet or other metal material sandwiched between two sheets of electronically conductive shield material. Activated carbon is manufactured using a binder such as polyethylene or PTFE adhered to and in electrical contact with the shield material of the current collector.
