“…The coordinate electrolyte was prepared by mixing the corresponding solvents and lithium salts in crimp‐cap sealed vials. DADMA‐TFSI (Figure S35, Supporting Information) and silica‐oxygen‐titanium (Si‐O‐Ti)‐coated alumina (Al 2 O 3 ) nanoparticles (Ti‐SiO 2 @Al 2 O 3 ) (Figure S36, Supporting Information) were prepared using the synthetic procedures of previous reports, [ 25,58 ] respectively. The morphology of Ti‐SiO 2 @Al 2 O 3 was characterized using field emission transmission electron microscopy (FETEM, JEM‐2100F, JEOL).…”

Despite their potential as post lithium‐ion batteries, solid‐state Li‐metal batteries are struggling with insufficient electrochemical sustainability and ambient operation limitations. These challenges mainly stem from lack of reliable solid‐state electrolytes. Here, a new class of single‐ion conducting quasi‐solid‐state soft electrolyte (SICSE) for practical semi‐solid Li‐metal batteries (SSLMBs) is demonstrated. The SICSE consists of an ion‐rectifying compliant skeleton and a nonflammable coordinated electrolyte. Rheology‐tuned SICSE pastes, in combination with UV curing‐assisted multistage printing, allow fabrication of seamlessly integrated SSLMBs (composed of a Li metal anode and LiNi0.8Co0.1Mn0.1 cathode) without undergoing high‐pressure/high‐temperature manufacturing steps. The single‐ion conducting capability of the SICSE plays a viable role in stabilizing the interfaces with the electrodes. The resulting SSLMB full cell exhibits stable cycling performance and bipolar configurations with tunable voltages and high gravimetric/volumetric energy densities (476 Wh kgcell−1/1102 Wh Lcell−1 at four‐stacked cells with 16.656 V) under ambient operating conditions, along with low‐temperature performance, mechanical foldability, and nonflammability.

“…Furthermore, in the same separator type and with the objective of enhancing thermal runaway, melaminebased porous organic polymer (POP) coatings [213] were implemented. In fact, different materials have been used as a layer on the surface of polyolefin separators to improve its wettability, including polyethyleneimine (PEI)/dopamine coating layer [188], Al 2 O 3 layers in electrospun PVDF nanofibers [193], ammonium persulfate (APS) coating [194], a phenolic resin (AF) layer with immersion in situ reaction [186], a thin layer of lowdensity polyethylene microspheres [199], polyamine (PAI) containing natural clay nanorods (attapulgite, ATP) [197], and polyvinyl alcohol (PVA) [214], TiO 2 [215], Al 2 O 3 [216], UVinduced graft with polar methyl acrylate (MA) [217], and polyimide (PI)-SiO 2 layers [218].…”

Environmental issues related to energy consumption are mainly associated with the strong dependence on fossil fuels. To solve these issues, renewable energy sources systems have been developed as well as advanced energy storage systems. Batteries are the main storage system related to mobility, and they are applied in devices such as laptops, cell phones, and electric vehicles. Lithium-ion batteries (LIBs) are the most used battery system based on their high specific capacity, long cycle life, and no memory effects. This rapidly evolving field urges for a systematic comparative compilation of the most recent developments on battery technology in order to keep up with the growing number of materials, strategies, and battery performance data, allowing the design of future developments in the field. Thus, this review focuses on the different materials recently developed for the different battery components—anode, cathode, and separator/electrolyte—in order to further improve LIB systems. Moreover, solid polymer electrolytes (SPE) for LIBs are also highlighted. Together with the study of new advanced materials, materials modification by doping or synthesis, the combination of different materials, fillers addition, size manipulation, or the use of high ionic conductor materials are also presented as effective methods to enhance the electrochemical properties of LIBs. Finally, it is also shown that the development of advanced materials is not only focused on improving efficiency but also on the application of more environmentally friendly materials.

“…The Al–O and Si–O lithiophilic polar functional groups will form compounds (Li x AlO y and Li x SiO y ) with the Li metal during battery cycling, which can effectively suppress Li dendrite formation and growth. 19,33,36–39 When annealed at 1500 °C in the presence of a silica sol, mullite fiber with 3D structure could be connected by dried silica and thus form mullite sheets. The 3D mullite fiber matrix has continuous voids and excellent mechanical strength, which can offer sufficient space for Li sustained deposition and relieve the volume change of the Li metal anode during cycling.…”
