Advanced Materials, EarlyView.A double‐sided mechanical interlocking strategy is developed to create robust electrical contact between polymer electrode and metal interconnect. The fibrous structure enables formation of thread–hole adhesion, which only breaks under bulk failure and achieves a record high interfacial energy exceeding 730 J·m−2. This adhesion secures the integrity of
