“…Another example of ion‐dipole interaction mechanism was shown by Jin and co‐workers. [ 176 ] They prepared a poly(vinylidene fluoride‐ co ‐hexafluoropropylene)/1‐ethyl‐3‐methylimidazolium bis(trifluoromethylsulfonyl)‐imide gel electrolytes (P(VDF‐HFP)‐[EMI][TFSI]) with strong ion‐dipole interactions between positively charged imidazolium cations and partially negatively charged fluorine atoms, presenting favorable self‐healing capability. The ion‐dipole interactions can also promote the ionization of lithium salts, resulting in the fast transport of Li + and dendrite‐free Li + plating.…”

The booming development of electronics, electric vehicles, and grid storage stations has led to a high demand for advanced energy‐storage devices (ESDs) and accompanied attention to their reliability under various circumstances. Self‐healing is the ability of an organism to repair damage and restore function through its own internal vitality. Inspired by this, brilliant designs have emerged in recent years using self‐healing materials to significantly improve the lifespan, durability, and safety of ESDs. Extrinsic and intrinsic self‐healing materials and their working principles are first introduced. Then, the application of self‐healing materials in ESDs according to their self‐healing chemistry, including hydrogen bonds, electrostatic interactions, and borate ester bonds, are described in detail. Based on these, critical challenges and important future directions of self‐healing ESDs are discussed.

“…As a consequence, the decreased intensity and the homogeneous distribution of the electric field resulted in controlled Li + reduction. This general methodology has also been extended to ether and gel electrolyte systems successfully . Zhang and co‐workers reported anion‐immobilized SSEs by incorporating garnet‐type Li 6.75 La 3 Zr 1.75 Ta 0.25 O 12 (LLZTO) NPs into polyethylene oxide (PEO)/Li bis(trifluoromethylsulphonyl)imide (LiTFSI) matrix (Figure b) .…”

Lithium (Li) metal with high theoretical capacity and the lowest electrochemical potential has been proposed as the ideal anode for high-energy-density rechargeable battery systems. However, the practical commercialization of Li metal anodes is precluded by a short lifespan and safety problems caused by their intrinsically high reductivity, infinite volume change, and uncontrollable dendrite growth during deposition and dissolution processes. Plenty of strategies have been introduced to solve the above-mentioned problems. Among these, controlling Li + flux plays a vital role to directly influence the plating and stripping process. In this work, the fundamental effect of Li + flux distribution on Li nucleation and early dendrite growth is discussed. Then, recent strategies of controlling Li + flux to suppress dendrite formation and growth through materials design are summarized, including homogenizing Li + flux, localizing Li + flux, and guiding gradient Li + distribution. Finally, underexplored materials are proposed and explored to control Li + flux and further directions for dendrite-free Li anodes. It is expected that this progress report will help to deepen the understanding of Li + flow tuning and morphology control of Li anodes and eventually facilitate the practical application of Li metal batteries.

A Self-Healing Polymer with Fast Elastic Recovery upon Stretching

et al. 2020

The design of polymers that exhibit both good elasticity and self-healing properties is a highly challenging task. In spite of this, the literature reports highly stretchable self-healing polymers, but most of them exhibit slow elastic recovery behavior, i.e., they can only recover to their original length upon relaxation for a long time after stretching. Herein, a self-healing polymer with a fast elastic recovery property is demonstrated. We used 4-[tris(4-formylphenyl)methyl]benzaldehyde (TFPM) as a tetratopic linker to crosslink a poly(dimethylsiloxane) backbone, and obtained a self-healing polymer with high stretchability and fast elastic recovery upon stretching. The strain at break of the as-prepared polymer is observed at about 1400%. The polymer can immediately recover to its original length after being stretched. The damaged sample can be healed at room temperature with a healing efficiency up to 93% within 1 h. Such a polymer can be used for various applications, such as functioning as substrates or matrixes in soft actuators, electronic skins, biochips, and biosensors with prolonged lifetimes.
