1. A lightweight high power battery, comprising:
an active structure including:
an anode electrode having a first side and a second side opposite the first side;
a first metal layer formed on the first side of the anode electrode;
a cathode electrode having a first side and a second side opposite the first side;
a second metal layer formed on the second side of the cathode electrode; and
a separator material arranged between the second side of the anode electrode and the first side of the cathode electrode;
a liquid electrolyte; and
a non-metallic pouch arranged to encapsulate the active structure and the liquid electrolyte, wherein the non-metallic pouch is bonded to a first portion of the first metal layer, the first portion being positioned between the non-metallic pouch and the anode electrode, and
wherein the non-metallic pouch is bonded to a second portion of the second metal layer, the second portion being positioned between the non-metallic pouch and the cathode electrode.
