1. A method for forming a battery comprising the steps of:

  • (a) providing a composite of (i) a magnetostrictive material and (ii) lead zirconate titanate (PZT) piezo material which generates electricity when subjected to magnetic field, said composite having a natural resonant frequency;

    (b) connecting said composite to a capacitor or ferro capacitor; and

    (c) subjecting said composite to a magnetic field having resonant frequency in the range of 90% to 110% of the natural resonant frequency of said composite.
