<p>A light transparent moisture barrier (70) useful for preventing moisture from destroying the effectiveness of a moisture sensitive cell condition tester (60) on an electrochemical cell (50) comprises a plurality of very thin, alternating layers (40, 38) of an inorganic material and an organic material on a flexible, polymeric substrate. The layers are not laminated, but are formed on the substrate (12) by a deposition or coating process and the thickness of the layer is less than 5 microns. The organic material is a hydrophobic polymer and the inorganic material is a metal oxide, nitride, a glass or silicon.</p> |
