Incorporation of ceramic materials into separators has been frequently applied in both research and industry to improve the overall high‐temperature performances of lithium ion batteries. However, inorganic ceramic particles tend to form aggregation in separators and even fall off in the separator matrix due to the inferior combination between ceramic particles and polymer matrix, giving rise to a decrease in separator porosity and thus the degradation of battery performances. Herein, a single‐layer core‐shell architecture is designed to reinforce the polymer matrix through encircling Al2O3 particles by poly(vinylidene fluoride) with strong inter‐molecular interaction. The 3D‐reinforced microstructure effectively improves pore distribution and thermal stability to resist the dimensional deformation at high temperatures, thus giving rise to a high Coulombic efficiency of 99.16% and 87.5% capacity retention after 500 cycles at 80 °C for LiFePO4/Li batteries. In particular, the excellent performances of the proposed separator microstructure are confirmed with a thickness value of commercial separators. This work provides a promising strategy to fabricate a core‐shell structural composite separator for stable lithium ion batteries at high temperatures.

“…Generally, doping salt is widely used and plays a vital role in the conduction of electrolytes. Numerous salts have been reported in the electrolytes for various electrochemical devices such as magnesium trifluoromethanesulfonate (MgTf 2 ) , lithium triflate (LiTF), lithium bis(oxalato)borate (LiBOB), lithium phosphate (LiPO 4 ), etc. ,− In DSSCs performance, the redox mediator is a vital electrolyte component that functions to regenerate dye and ionic transport between the working electrode and counter electrode. , Commonly in DSSC, iodide/tri-iodide (I – /I 3 – ) redox pair is the most favorite choice for efficient performance . These redox pairs have produced efficiency up to 12.6% under the sun illumination achieved by the EPFL group. , Besides, incorporating iodide salt into the electrolytes could affect their ionic conductivity as well as the J SC of DSSC.…”

Dye-sensitized solar cells (DSSCs) are a suitable replacement for conventional silicon solar cells due to their unique features, such as high energy conversion efficiency and cheap manufacturing cost. The liquid-state DSSCs, however, are poorly sustainable on a long-term basis because volatile liquids are used. The early intention of incorporating polymer into the liquid electrolytes was to curb the problem encountered by liquid electrolytes and enable the DSSCs to function as a long-term stability device. This work briefly reviews how the improvisation has been done on the polymer electrolytes formulation and the extent of how each element can affect the cell efficiency and long-term stability. The role of each component, such as the type of host polymer, iodide salts, nanoparticles, and organic additives that improve the performance of DSSCs, has also been highlighted. This clarified the main purpose of introducing various types of additives into electrolytes to enhance the transport properties as well as the performance of the DSSCs.

“…Particularly, lithium metal has been broadly deemed the favorable anode attributable to the merits of its large theoretical specific capacity and its lower electrode potential. For decades, researchers have been researching lithium metal batteries, [12–16] but the liquid organic electrolyte used by conventional lithium‐ion batteries simply produces side reactions during charging and discharging, which causes an irreversible reduction in battery capacity [17–20] . Meanwhile, the Li metal anode cannot be employed directly in liquid electrolyte‐based Li batteries owning to the unwanted development of Li‐dendrites [20–22] .…”

Hybrid composite electrolytes incorporate polymer matrixes and garnet filler attract the focus of concern for all‐solid‐state batteries, which possess high ionic conductivity, superior electrochemical stability, and wide electrochemical window of ceramic electrolyte advantages, and exhibit excellent flexibility and tensile shear strength from polymer electrolyte benefits. Hence, the unique structure design of solid‐state electrolytes resolves the existing defects that the use of either single garnet or polymer electrolytes implemented into battery devices. This review summarizes Li7La3Zr2O12 (LLZO)/polymer solid composite electrolytes (SCEs), comprising LLZO/polymer SCEs with various structures and different ratios of LLZO fillers, LLZO/polymer with different kinds of polymers matrix and hybrid lithium‐salt, and Li+ transport pathways within the LLZO/polymers SCEs interface. The purpose here is to propose the viewpoints and challenges of LLZO/polymer SCEs to promote the development of next‐generation solid electrolytes.
