Abstract
The present invention relates to multilayer packaging structure (10) for a thin film battery (5) wherein a metal layer (14) is sandwiched between a first layer (11) and a second layer (12). A first opening (21) is arranged in the first layer (11) such that a first portion (24) of the metal layer (14) associated with the first opening (21) is exposed and is configured to be able to be in electrical contact with a current collector of the thin film battery (5). A second opening (22) is arranged in the second layer (12) such that a second portion (25) of the metal layer (14) associated with the second opening (22) is exposed and is configured to be able to be electrically connected to an external circuitry. The invention further relates to a method (30) for manufacturing of the multilayer packaging structure (10).
