Self-healability is an attractive feature for next generation energy-storage devices aiming at flexible/wearable electronics. However, realizing self-healability usually involves complicated molecular design and synthetic processes. Here, we demonstrate that sodium hyaluronate (SH), a kind of natural polysaccharide, can be used as a versatile polymer to facile fabricate intrinsically self-healable energy-storage devices. Self-healable sodium ion batteries and asymmetric capacitors are components into dynamic SH networks cross-linked via borate ester bond fabricated by integrating their electroactive ing. The devices autonomously recover their configuration integrity, microstructure, and mechanical and electrochemical properties even after nine cycles of breaking/healing, exhibiting excellent reliability, easy maintenance, and superior safety. The electrochemical performances and self-healability are estimated to be the best among those of the existing self-healable energy-storage devices. This facile and versatile strategy might greatly accelerate the design and fabrication of smart and robust energy-storage devices applicable for advanced flexible electronics or soft robot, and so on.
