Stretchable batteries based on SLIC. a Optical photograph of the conformable battery based on all SLIC components. b Cross-sectional view of the SLIC battery showing the layout of the components. c Capacity versus cycle number for a full-cell based on stretchable SLIC components. The active material loading in the electrodes (LFP or LTO) is 70 wt.%, ~1.1 mAh cm⁻². d Discharge capacity of an all-SLIC stretchable battery after several cycles of 50% strain. Discharge capacity is measured after each set of 10 stretching cycles. e Performance of an all-SLIC stretchable battery under 0 and 70% strain. f Demonstration of a stretchable SLIC battery providing power to a red LED under no strain, stretched 70%, folded, and returned to its original position.
