Abstract

The present invention is a method of fabricating a rechargeable battery structure by extracting plasticizer from plastic battery preforms to render them insensitive to water while maintaining the homogeneous characteristics of the plastic materials to allow subsequent activation of the batteries through the introduction of an electrolyte solution. These battery preforms need not be maintained under anhydrous conditions and can be activated immediately preceding use thereof.
