Received: 11 May 2024; Revised: 19 June Accepted: 22 July Published: 14 August 2024 Abstract: batteries are crucial powering portable electronic devices electric vehicles, profoundly impacting our global society. However, their repeated charge discharge cycles cause structural changes that lead mechanical fractures in the internal components, significantly reducing cycling lifetimes lithium batteries. Utilizing intrinsic self-healing polymers is a promising strategy address these issues, as materials can spontaneously repair cracks or damages, resulting greatly enhanced electrochemical performance. In this review, we present highlight how contribute improved performance We first introduce mechanisms identified current functions, including external self-healing. Then, discuss effects on different electrolyte binder materials. examples illustrating efficacy extending cycle life improving battery stability discussed. Finally, propose some challenges future opportunities evolving field stimulate rational design advanced stable
