An energy storage device, comprising:
- a first electrode;
- one or more thin-film layers deposited on the first electrode;
- a second electrode with a calendared ion containing layer in contact with the one or more thin-film layers,
- wherein the one or more thin film layers provides electrical isolation and ionic conductivity between the first electrode and the second electrode.
A method of forming a battery cell, comprising:
- depositing one or more thin films on a first electrode;
- calendaring an ion containing layer on a second electrode;
- joining the first electrode with the second electrode such that the one or more thin films is in contact the ion containing layer;
- and
- lithiating the one or more thin films to form the battery cell.
