UrduResearchers have developed the first-ever stretchable and self-healable lithium-ion battery with all-in-one configuration. The battery can steadily provide power for a timer even after being stretched. Additionally, after being damaged and subsequently healed, the battery can still steadily serve as a power source to light up an LED.
