The present disclosure relates to a composition for encapsulating an organic electronic element and an organic electronic device comprising the same, and provides an encapsulation composition which can form an encapsulation structure capable of effectively blocking moisture or oxygen introduced from the outside into the organic electronic device, thereby securing the lifespan of the organic electronic device and implementing endurance reliability of the encapsulation structure at high temperature and high humidity, and has high shape retainability, and an organic electronic device comprising the same.

Composition for encapsulation

The present disclosure relates to an encapsulation film and an organic electronic device comprising the same, which provides an encapsulation film having excellent resilience without causing plastic deformation, while having flexible and rollable characteristics, as well as implementing excellent moisture barrier characteristics, and an organic electronic device comprising the same. The encapsulation film includes an encapsulation composition which includes a block copolymer having a first block derived from a monomer having a glass transition temperature of 0° C. or higher, and a multifunctional oligomer, where, after the encapsulation film is stretched 200% (2 times the existing length) in the longitudinal direction under conditions of a temperature of 25° C. and 60% relative humidity and left for 24 hours, the degree of restoration at the time of removing the stretched force and measuring the length after 1 hour is within 110% of the existing length.

Encapsulation film

The present invention relates to an eddy current sensor for detecting a crack in a battery cell, and a system for detecting a crack of a battery cell including the eddy current sensor. According to the present invention, it is possible to easily detect a crack generated in an electrode, an electrode tab or a welded portion.
