The assembled battery could be subjected to twisting, bending and stretching which could maintain structural integrity. However, it was observed that capacity loss was 35% and energy density decreased from 35 to 17 Wh kg −1 when the thin film battery was stretched to 50%.
Stretchable energy storage devices (SESDs) are indispensable as power a supply for next-generation independent wearable systems owing to their conformity when applied on complex surfaces and functionality under mechanical deformation.
A stretchable fiber-shaped Li-ion battery was successfully fabricated through the spring structure and the elastic substrate. As shown in Figure 10d, the assembled fiber-shaped battery could be stretched to 100% with capacity retention of 90% and low battery resistance fluctuation of 1%.
We can see that discharge voltage plateau (≈2.5 V), internal resistance and charge transfer resistance could be well maintained after the Li-air battery was stretched to 100%. Even at high stretching speed and after 1000 stretching cycles, the electrochemical performance remained stable.
Mechanical stretchability was achieved by the simple pre-strain-then-releasing strategy. The fabricated fiber-shaped supercapacitor was first attached to a 100% pre-strained elastic fiber. Buckled fiber-shaped supercapacitor was then formed with a stretchability up to 100% after releasing the elastic fiber.
Subsequently, pulling two parallel sides could unfold the battery along the creases, thus realizing stretch capability. An areal deformability of 1600% could be obtained. During expanding and folding, strain takes place at the creases and vertices while the parallelograms experience body motion but strain-free.
