A solid state battery of at least one electrochemical cell comprises a positive electrode (2), a negative electrode (4) and a solid electrolyte material (3) which are assembled as a laminate which is then folded back on itself, a layer of an electrically non-conducting foraminous material (5) being incorporated within the solid electrolyte material (3) in the region of the fold in the laminate. The foraminous material (5) may be polypropylene and may be perforated. Foraminous material (5) may be provided in the region of each of a plurality of folds. |
