1. A process to produce a lithium ion battery comprising the steps of:
a. providing an electrode having at least one metallized substrate with a coating of an ion storage material and a separate polymer substrate layer;
b. providing a counterelectrode;
c. layering said electrode and counterelectrode opposite each other with a separator component interposed between said electrode and said counterelectrode;
d. providing a package material including an electrical contact component, wherein said electrical contact component includes a portion present internally within said package material and a portion present external to said package material;
e. electrically connecting said electrical contact component with said at least one metallized substrate wherein at least one metal layer of said at least one metallized substrate is pressed through said separate polymer substrate layer of said at least one metallized substrate to make an electrical connection with resistance less than 1 ohm with said electrical contact component;
f. introducing at least one liquid electrolyte with ions internally within said package material; and
g. sealing said package material.
