Abstract
The method for patterning a polymer layer arranged on a support comprises deposition of a layer made from a lithium-based polymerization inhibitor material on a first area of the support, deposition of a cationically polymerizable material on the polymerization inhibitor layer and on a second area of the support, application of polymerization treatment resulting in a non-solidified sacrificial layer in the first area and the polymer layer in the second area, and elimination of the sacrificial layer.
Claims10
A method for patterning a polymer layer arranged on a support comprising the following steps:
- depositing a layer made from a lithium-based polymerization inhibitor material on a first area of the support,
- depositing a cationically polymerizable material on the polymerization inhibitor layer and on a second area of the support,
- subjecting the cationically polymerizable material to polymerization treatment resulting in a non-solidified sacrificial layer in the first area and said polymer layer in the second area, and
- eliminating the sacrificial layer.
A method for packaging a lithium microbattery arranged on a support, comprising the following steps:
- depositing a layer made from a lithium-based polymerization inhibitor on the support at the periphery of the microbattery,
- depositing a cationically polymerizable material on the whole of the microbattery and on the polymerization inhibitor layer,
- subjecting the cationically polymerizable material to polymerization treatment resulting in a non-solidified sacrificial layer at the periphery of the microbattery and a polymer layer covering the microbattery,
- depositing a layer forming a protective barrier on the polymer, layer and covering the whole of the microbattery,
- eliminating the sacrificial layer and the polymerization inhibitor layer.
