  • Patent number: 11362371
    Abstract: A method for manufacturing a battery component includes unrolling a polymer foil from a roll; forming windows into the unrolled polymer foil; and placing a battery cell component over each window. The battery cell component advantageously can be a solid-state electrolyte functioning as a separator, which is thereby well protected for handling and in later use.
