Claim 8:
9. A lithium battery structure, comprising:
a first and a second battery units, each of the battery units including a first current collector, a first active material layer, a second active material layer and a second current collector, wherein the first current collector comprises:
a conductive substrate, having a first surface, a second surface opposite and parallel to the first surface and a plurality of through holes extended from the first surface to the second surface; and
an isolation layer, disposed on the first surface of the conductive substrate and essentially covering completely the first surface and sidewalls of the through holes, and extending to cover parts of the second surface;
wherein the first active material layer is disposed on an uncovered area of the second surface, and the second active material layer and the second current collector sequentially disposed on the first surface of the conductive substrate completely covered by the isolation layer;
wherein the first and the second battery units are essentially face-to-face disposed to each other by the first active material layers;
an ion guiding layer, disposed between the first active material layers of the first and the second battery units; and
a packaging structure, disposed between the second current collectors of the first and the second battery units to package the first and the second battery units;
wherein
the ion guiding layer extends into the through holes of the conductive substrate;
the ion guiding layer is essentially only made of an ion-transmission material;
the packaging structure includes a first package body sandwiched between the second current collector and the first current collector of the first battery unit, a second package body sandwiched between the first current collector of the first battery unit and the first current collector of the second battery unit, and a third package body sandwiched between the first current collector and the second current collector of the second battery unit;
the first current collectors of the first and the second battery units and the second package body form an enclosed space for depositing the ion guiding layer therein; and
a distance between the first active material layers of the first and the second battery units is 5-100 micrometers.
