Abstract
Official abstract text for this publication.
Provided is an oxygen permeable membrane for use in an air secondary battery, which excels in oxygen permeability, barrier performance to water, being capable of preventing electrolyte from leaking out. Such an oxygen permeable membrane includes a thermoplastic resin membrane and inorganic particles having pores having pore diameter of 10 Å or less contained in the thermoplastic resin membrane, in which the thermoplastic resin membrane has one surface on which hydrophobic treatment is effected.
First claim
Opening claim text (preview).
What is claimed is: 1. An armouring material for use in an air secondary battery, comprising an armouring sheet constituted by laminating an outer layer including heat-resistant resin film, a metal foil layer, and an inner layer including a thermoplastic resin film, being equipped with an opening part for taking oxygen in, perforating through the outer layer, the metal foil layer and the inner layer, and an oxygen-permeable membrane being joined to an inner layer side in an ope…
