What is a stretchable structure based battery?

For stretchable structure-based batteries, island-bridge batteries can use commercial batteries as the "island" part, while wave-shaped, origami, and Kirigami batteries can also employ traditional electrode materials, which helps reduce their manufacturing costs.

How do Kirigami and origami batteries achieve stretchability?

Origami and Kirigami batteries achieve stretchability through the geometric design of planar batteries, avoiding the performance degradation caused by inactive materials. Another promising approach involves the direct use of stretchable soft materials to fabricate stretchable batteries.

What are the applications of stretchable batteries?

Initially, we summarize the applications of stretchable batteries in the field of flexible electronics, including electronic skin, digital healthcare, wearable devices, and flexible displays. Subsequently, we interpret the structures of stretchable batteries that have been proposed to date.

Can stretchable batteries be made from soft materials?

An alternative strategy to achieve stretchable batteries lies in the use of stretchable soft materials. Unlike structural designs, which may encounter issues such as mechanical fatigue, limited conformability, and manufacturing complexity, soft materials inherently possess low Young's modulus and excellent mechanical compliance.

How to fabricate flexible/stretchable batteries?

In order to fabricate flexible/stretchable batteries, therefore, the traditional rigid materials for electrodes and current collectors need to be replaced with soft conductor materials. Also, gel electrolytes, instead of the conventional liquid or solid electrolytes, should be used.

Can stretchable batteries be used in wearable electronics?

Although the research on stretchable batteries is just a recent development, it has attracted a great deal of interest and various stretchable batteries, such as stretchable Zn-based batteries and Li-ion batteries [32, 88], have been reported to show potentials in wearable and stretchable electronics.
