More Information
Summary: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. Une barrière (70) transparente, contre l'humidité, est utilisée pour empêcher l'humidité d'annuler l'efficacité d'un testeur (60) d'état de pile sensible à l'humidité sur une pile électrochimique (50). Cette barrière est constituée d'une pluralité de couches alternées, très fines (40, 38), d'un matériau inorganique et d'un matériau organique sur un substrat polymère, flexible. Les couches ne sont pas stratifiées, mais sont formées sur le substrat (12) par un processus de dépôt ou revêtement, l'épaisseur de la couche n'excédant pas 5 microns. Le matériau organique est un polymère hydrophobe et le matériau inorganique est un oxyde métallique, un nitrure, un verre ou un silicium.
