Abstract
The invention provides a compressed envelope of solid electrolyte for holding an electrode in an electrochemical cell. The envelope comprises corrugated sheets joined along their edges. The sheets are aligned with each other so that their corrugations extend parallel along the length of the envelope and a space is defined between the sheets. The corrugations of the sheets nest in each other where the sheets are joined together at the ends of the envelope. The invention also provides a method of making the envelope and a cell having an electrode held in said envelope.
