1. A method of activating an electrochemical cell precursor package which comprises the steps of:

  • (a) forming an electrochemical cell precursor package, said electrochemical cell precursor package including a moisture-impervious material having a sealable aperture therethrough, said material containing a porous structure comprising;

    (i) an anode(ii) a cathode; and

    (iii) a polymeric matrix interposed between said anode and said cathode; and

    (b) adding a quantity of activation fluid through said sealable aperture of the electrochemical cell precursor package at a rate such that substantially all of the activation fluid is incorporated into the porous structure.
