Abstract
A battery assembly can be formed on a base layer provided on a temporary process 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 bonded to a transfer layer, and the process substrate can be removed for assembly into a battery system.
Claims20
A method of assembling a battery, the 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;
- bonding the thin film battery stack to a transfer layer;
- transferring the thin film battery stack from the process substrate;
- and
- assembling the thin film battery stack into a battery system.
