Method for making electrodes for double layer capacitors
Abstract
A method of making electrodes for use in double layer capacitors comprising adding to a carbon powder-electrolyte mix an excess of liquid to render the mix pumpable, moderately overfilling an electrode cavity with the mix and removing the excess liquid in an equilibration step so that the remaining mix substantially fills the electrode cavity.
