Abstract
A method of sealing an ultracapacitor substantially free of water is disclosed. The method includes providing a multilayer cell comprising two solid, non porous current collectors, separated by two porous electrodes with a separator between the two electrodes, sealing the cell with a reclosable hermetic closure. Water inside the closure is dissociated by an applied voltage to the cell and escapes in the form of hydrogen and oxygen when the closure is unmated, the closure is then mated to hermetically seal the cell which is substantially free of water.
