Self-healing polymers (SHP) are the polymers that have the capability to recover the material from any physical damage by responding to the damages or cracks in the material and heal the same. This self-healing technology gives the polymers ability to recover from the cracks at an early stage by preventing them from any catastrophic failures, which increases the scope of applications of these materials. This review article highlights the key points on extrinsic self-healing polymer and intrinsic self-healing polymer by comparing their healing efficiency, advantages, disadvantages, and challenges in the prospect of their future development as well as their possible applications in space industry and construction of roads.

The conductive polymer electrodes are considered as the best fabrication in the production of rechargeable batteries. The idea underlying its use, as well as the process and foundation of cell fabrications based on various types of conducting polymer systems are discussed in this review. Various types of conductive polymer coating on anode current collector along with different routes to provide desirable coated layers are discussed in detail. This review shows that the modified copper current collector can be regarded as an effective protective layer against solid electrolyte interface (SEI) film, electrode particle cracking, cathode electrolyte formation (CEI), dendrite formation/lithium plating, electrolyte decomposition, etc. not only because of their productivity, availability, but also for their stability, cost‐efficiency, and helps to decrease the internal resistance as well.
