Abstract
A battery assembly can be formed on a base layer provided on a substrate, with a thin film battery stack including an anode layer, a cathode layer, and an electrolyte layer between the anode and cathode layers. The thin film battery stack can be attached to a pattern film layer with holes for electrical connection to the anode and cathode layers.
Claims20
An assembly method comprising:
- forming a base layer on a process substrate;
- forming a thin film battery stack on the base layer, the thin film battery stack comprising at least an anode layer, a cathode layer, and an electrolyte layer between the anode layer and the cathode layer;
- and
- attaching the battery stack to a patterned layer having pattern holes configured for electrical power connection to the thin film battery stack.
The method of claim 9, further comprising forming a cathode collector layer as an electrically conducting bond between the adjacent pair of cathode layers.
The method of claim 10, wherein stacking the plurality of thin film battery cells comprises stacking at least a pair of the anode layers in an adjacent and electrically coupled relationship within the battery assembly, and further forming an anode collector layer as an electrically conductive bond between the adjacent pair of anode layers.
A battery system comprising:
- a plurality of thin film battery cells arranged in a stacked configuration, each of the thin film battery cells comprising an anode layer, a cathode layer, and an electrolyte layer between the anode layer and the cathode layer;
- a patterned film layer having pattern holes configured for electrical power connection to the stacked configuration of thin film battery cells.
A device comprising:
- a display;
- a controller coupled to the display;
- and
- a battery assembly coupled to the controller and configured for powering the display, the battery assembly comprising:
- a plurality of thin film battery cells arranged in a stacked configuration, each of the thin film battery cells comprising an anode layer, a cathode layer, and an electrolyte layer between the anode layer and the cathode layer;
- and
- a patterned layer having pattern holes configured for electrical power connection to the stacked configuration of thin film battery cells.
