All‐in‐One 3D Printing for Highly‐Stretchable Zn Metal Batteries: Resolving the Dilemma Between Mechanical Compliance and Electrochemical Stability
Aqueous Zn‐ion batteries (ZIBs) hold great promise for flexible energy storage owing to their inherent safety and cost‐effectiveness. However, their integration into stretchable power sources remains fundamentally challenged by strain‐induced interfacial instability, which disrupts electrode‐electrolyte contact, ac...
