Trends and Developments in Capacitor Technologies for Power Electronics Applications

In a primary-cell of the type in which a cathode or anode increases its apparent volume as the discharge proceeds, thereby absorbing the electrolyte, at least between a cell enclosure which serves as one of the terminals of the primary-cell or top closure and the cathode or anode electrically connected thereto is interposed a spacer which contains electrolyte, is electrically conductive and reduces its apparent volume when the pressure is applied thereto, thereby squeezing the electrolyte out of it.
