SEPARATOR BASED ON FIBROUS CERAMIC MATERIAL FOR ULTRACAPACITORS, EDLC, HYBRID CAPACITOR, FUEL CELL AND BATTERY

摘要

A separator such as for an electrochemical double layer capacitor includes acicular inorganic particles that are dried to form a porous membrane. Example inorganic particles are calcium silicate particles, alumina fibers, magnesium aluminosilicate glass fibers, titania fibers, and combinations thereof. The electrode layer comprises activated carbon, carbon black, and a binder. A deposition method implementing slurry that includes the acicular inorganic particles and a dispersing medium along with a binder material can be used to form the separator layer directly on electrode materials.
