“…However, the relatively poor thermostability and ionic conductivity restrict further application in electrical energy storage equipment. [55,56] In recent years, through introducing lithium salts and metal-oxide particles, polymer composite electrolytes exhibit improved thermal stability and a wider operating temperature range. Additionally, Lewis-acid sites and pores in inorganic fillers can effectively facilitate the segmental movement of polymer chains as well as the transportation of metal ions, thereby improving the ionic conductivity as well as the electrochemical performance of the SSEs.…”

Nowadays solid‐state batteries have become a hot spot in the research of batteries and a significant candidate for commercial batteries for the increasing demands for good safety and excellent energy density. Metal‐organic frameworks (MOFs) have been considered as suitable materials for solid‐state electrolytes (SSEs) for the merits of regular channels and large specific surface areas, which can provide a promising structural platform for fast‐ion conduction. Therefore, numerous kinds of MOF‐based SSEs with enhanced electrochemical performance have been successfully synthesized and studied in recent years. In this review, the recent progress (synthesis methods, physical and chemical characteristics) of MOF‐based SSEs for secondary batteries have been summarized. Finally, the challenges and opportunities faced by the future development in this field are put forward, hoping to provide some enlightenment for the synthesis of MOF‐based SSEs, so as to create more efficient, long‐lasting, and safe SSE‐based secondary batteries.

“…In the lithiation process, Electrochromism leads to resistive switching ((BA) 2 (MA) 3 Pb 4 Br 13 ; BA is butylammonium) through the intercalation of Li-ions in 3D and quasi-2D films. [137] A. Mathieson et al [136] have also provided a mechanism to effectively control Li doping in HPs, which is a longstanding challenge in optoelectronic devices. They proposed a solid-state lithiumion battery device structure that can extrinsically control the doping of Li + in MAPbBr 3 HPs (Figure 7a).…”

The flexibility and adaptability of halide perovskites position them as a promising material for a variety of cutting‐edge technologies. In addition to their primary applications in photovoltaics and light‐emitting diodes, they have recently garnered interest for potential use in switchable technologies, such as smart windows, switchable photovoltaics, memory devices, neuromorphic computing, and sensors. This interest stems from these switchable properties, which allow them to alter color or other physical properties in response to external stimuli like heat, electric fields, light, pressure, and moisture. This review investigates their switching properties and examines their practical applications across a range of emerging chromic technologies. An in‐depth analysis of the mechanisms of reversibility, switchable optical and electrical properties, as well as the chemical and structural transformations these materials undergo is also presented. Furthermore, they are categorized based on their unique switching mechanisms. To assist the research community in developing new multichromic halide perovskite designs, several essential criteria are outlined for effective switchable materials. Lastly, the current challenges faced by these emerging materials are discussed, and a perspective on future developments and potential breakthroughs in this promising research area is offered.

“…[11] Solid polymer electrolyte (SPE) has become an important development direction and theoretical research hotspot of solid-state battery industrialization due to its excellent machining performance and interface compatibility. [12] However, there are still many defects that seriously hinder its further practical application, such as low ionic conductivity at room temperature (about 10 −7 S cm −1 ), poor interface contact with electrode material (interface impedance increases), poor stability (thermal stability and interface stability), low mechanical strength (difficulty in inhibiting lithium dendrites and short circuits), etc. [13] In view of the above problems that limit the large-scale application of solid polymer electrolyte, the preparation strategy of "in-situ solidification" for solid-state battery emerged.…”

Solid‐state lithium‐metal batteries constructed by in‐situ solidification of cyclic ether, are considered to be a critical strategy for the next generation of solid‐state batteries with high energy density and safety. However, the poor thermal/electrochemical stability of linear polyethers and severe interfacial reactions limit its further development. Herein, in‐situ ring‐opening hybrid crosslinked polymerization is proposed for organic/inorganic hybrid polymer electrolyte (HCPE) with superior ionic conductivity of 2.22×10−3 S cm−1 at 30°C, ultrahigh Li+ transference number of 0.88, and wide electrochemical stability window of 5.2 V. These allow highly stable lithium stripping/plating cycling for over 1000 h at 1 mA cm−2, which also reveal a well‐defined interfacial stabilization mechanism. Thus HCPE endows assembled solid‐state lithium‐metal batteries with excellent long‐cycle performance over 600 cycles at 2 C (25°C) and superior capacity retention of 92.1%. More importantly, our proposed non‐combustible HCPE opens up a new frontier to promote the practical application of high safety and high energy density solid‐state batteries via in‐situ solidification.This article is protected by copyright.
