A stretchable alkaline battery based on a embedded stretchable silver fabric is fabricated with an open circuit potential (OCV) of 1.5 V and capacity of 3.775 mAh/cm2. No drop in discharge capacity is observed with strain up to 100%. Two batteries connected in series continued to power a red LED even when stretched to 150% and twisted by 90 degrees.
