➀ Researchers from Jilin University in China have developed a self-healing, stretchable lithium-ion battery designed for wearables and flexible electronics. The battery is capable of healing itself after being cut and can stretch up to 220% of its original length. ➁ The technology uses dynamic covalent polymers and imine bonds for electrolyte and electrode binding, ensuring both stretchability and self-healing properties. ➂ The batteries have been tested successfully with an average discharge capacity of 126.4mAh/g⁻¹ and the potential for application in smart textiles and medical devices.
