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. 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.

Ceramic separator for ultracapacitors

A method of forming an electrolyte solution involves combining ammonium tetrafluoroborate and a quaternary ammonium halide in a liquid solvent to form a quaternary ammonium tetrafluoroborate and an ammonium halide. The ammonium halide precipitate is removed from the solvent to form an electrolyte solution. The reactants can be added step-wise to the solvent, and the method can include using a stoichiometric excess of the ammonium tetrafluoroborate to form a substantially halide ion-free electrolyte solution. Filtration can be done at low temperatures to reduce the amount of excess bromide in the resulting electrolyte.

A method of forming an electrolyte solution involves combining ammonium tetrafluoroborate and spiro-bi-pyrrolidinium bromide in a liquid solvent to form spiro-bi-pyrrolidinium tetrafluoroborate and an ammonium halide. The ammonium halide precipitate is removed from the solvent to form an electrolyte solution. The reactants can be added step-wise to the solvent, and the method can include using a stoichiometric excess of the ammonium tetrafluoroborate to form a substantially halide ion-free electrolyte solution.
