1. A lithium battery structure, comprising:
a first battery unit and a second battery units, each of the first battery units and the second battery unit including a first current collector, a first active material layer, a second current collector, a second active material layer, and an ion guiding layer;
wherein the first current collector comprising: a conductive substrate having a first surface and a second surface opposite and parallel to the first surface, a plurality of through holes extended from the first surface to the second surface, and an isolation layer;
wherein the isolation layer is disposed on the first surface of the conductive substrate, wherein the isolation layer covers essentially completely the first surface, completely covers sidewalls of the through holes, and extends to cover parts of the second surface;
wherein the first active material layer is disposed on areas not covered by the isolation layer of the second surface of the first current collector; wherein the first active material layer is separated from the sidewalls of the through holes by the isolation layer;
wherein the second active material layer and the second current collector are sequentially disposed on the first surface of the conductive substrate;
wherein the ion guiding layer is disposed between the first active material layers of the first battery unit and the second battery units;
wherein the ion guiding layer and the isolation layer separate the first current collector of the first battery unit from the first current collector of the second battery unit;
wherein the ion guiding layer covers the first active material layer, and extends into the through holes of the conductive substrate; and
a packaging structure, wherein the packaging structure is disposed between the second current collectors of the first battery unit and the second battery units to package the first battery unit and the second battery units.
