“…They also can be used as additives in conventional electrolytes with low viscosity to obtain composite electrolytes with both excellent conductivity and safety [21]. They can be filled in polymer frameworks or ionic gels to obtain solid electrolytes with excellent electrical conductivity and mechanical properties [22,23]. They can participate in the reaction with lithium metal electrodes as an electrolyte component to form a functional SEI film containing specific elements such as F, N [23,24].…”

SHPs include autonomous and nonautonomous systems according to the difference of self-healing behaviors. A nonautonomous system requires external triggers, like light, heat, pH, or chemical reagents, to achieve self-healing purposes, while the autonomous system initiates the self-healing process upon damage without any triggers or external stimuli (Figure 2). Additionally, according to the self-healing principles, the SHPs can be categorized into intrinsic and extrinsic SHPs.

“…Other researchers discussed the introduction of ionic liquids into polymer electrolytes. [203,204] In these materials, the strong electrostatic ion-dipole and ion-ion interactions between the dissociated salts and selected portions of polymeric chains favor the formation of intrinsically self-healable crosslinked networks inhibiting lithium dendrites. Even though all the examples reported so far exploited SSEs or GPEs, also selfhealing liquid electrolytes could be envisaged for LMBs.…”

An improved lifetime can be achieved by exploiting higher intrinsic durability of the materials, or by repairing the deteriorated component and restoring its original properties. Indeed, in the last years, several attempts to improve the lifetime of widespread devices (prosthetics, batteries, solar cells, lighting devices, etc.) were reported. [4-8] However, traditional techniques (welding, gluing, patching) need in situ application of fresh healing materials, and are not applicable to many modern complex devices that require disassembly and targeted operations well beyond the expertise of the final user. Moreover, repair by specialized personnel may be impossible or unsustainable from an economic point of view. To overcome these problems, a radically new strategy that can pave the way for more durable materials is emerging: the concept of selfhealing (SH). [9] This term refers to those smart materials that can automatically restore some, or all, of their functions after having suffered of an external damage that degraded their original properties. This usually has to do with autonomous recovery of physical cracks, but may include a wider range of features prolonging the lifetime of a material/ device, which space from anticorrosion to bactericidal properties. [10,11] By tailoring an appropriate response of the system, it becomes possible to design a material that can respond to various external perturbations and accommodate their eventual disturbance. The idea at the base of this approach is usually defined as biomimetic, since it takes inspiration from nature and mimic it in solving complex technological problems. [12] During the years, many different materials or technologies, naively depicted in Figure 1a, have taken inspiration from nature (as Velcro tape which mimics tiny hooks on bur fruits, naturally ventilated facades that mime termites' mounds, hydrophobic lotus-leaf coatings, and iridescent or adhesive surfaces respectively inspired by butterflies and geckos) and self-healing is not an exception. [13-15] In fact, in nature many organisms are capable of healing damages and of restoring their functionalities: skin, bones, plants, and other living systems can sense any failure and reconstruct the injured biological part which recovers its original functionalities. [16-18] Since these features lengthen the life of natural living beings, analog mechanisms can be exploited in artificial self-healing materials to benefit the Major improvements in stability and performance of batteries are still required for a more effective diffusion in industrial key sectors such as automotive and foldable electronics. An encouraging route resides in the implementation into energy storage devices of self-healing features, which can effectively oppose the deterioration upon cycling that is typical of these devices. In order to provide a comprehensive view of the topic, this Review first summarizes the main self-healing processes that have emerged in the multifaceted field of smart materials, classifying them on the basis of t...
