“…The semicircle disappears as temperature increases due to the reduction of the total resistance resistance. [31,32] By incorporating LLZO (CSE1) and LLZTO (CSE2) particles as fillers into the PEO-based electrolytes the bulk conductivity was found to be 5.85×10 À 6 , 7.40×10 À 5 S cm À 1 at RT, and the ionic conductivity of 1.06 and 1.45 S cm À 1 at 90 °C, respectively (Figure S4). Similarly, Zheng Zhang et al reported that the composite solid electrolytes (CSEs) used two different oxide fillers 10 wt% of LLZO and LLZTO ceramic filler offered the ionic conductivity of 1.7×10 À 4 S cm À 1 at 30 °C.…”

LiFePO4 (LFP) is widely used as cathode material for its low cost, high safety, and good thermal properties. It is one of the most exploited cathode materials for commercial Li‐ion batteries (LIBs). Herein, we present a screen‐printing method to prepare a LFP composite cathode, and a rational combination of the typical composite solid electrolytes (CSE) consisting of polyethylene oxide (PEO)/Li‐salt (LiTFSi) electrolyte with ceramic filler (LLZO or Li6.4La3Zr1.4Ta0.6O12 (LLZTO)) has been successfully demonstrated for SSB. The prepared CSE offers: i) a promising ionic conductivity (0.425 mS cm−1 at 60 °C), ii) a wide electrochemical window (>4.6 V), iii) a high Li‐ion transference number (tLi+=0.44), iv) a good interfacial compatibility with the electrode, v) a good thermal stability, and vi) a high chemical stability toward Li metal anode. The Li/CSE/Li symmetric cells can be cycled for more than 1000 h without Li‐dendrites growth at a current density of 0.2 mA cm−2. The final cell screen‐printed LFP composite cathode (LFP+LLZO)//Li metal displays a high reversible specific capacity of 140 mAh g−1 (0.1 C) and 50 mAh g−1 (0.5 C) after 1st and 500th cycles.

“…Li‐ion transference number ( t Li + ) is a crucial parameter for polymer electrolytes because the high t Li + can decrease the electrode polarization and promote the uniform deposition of Li + [19] . Figure 3a demonstrates the time‐dependent response of the direct‐current polarization and electrochemical impedance spectra before and after chronoamperometry.…”

The deployment of lithium metal anode in solid‐state batteries with polymer electrolytes has been recognized as a promising approach to achieving high‐energy‐density technologies. However, the practical application of the polymer electrolytes is currently constrained by various challenges, including low ionic conductivity, inadequate electrochemical window, and poor interface stability. To address these issues, a novel eutectic‐based polymer electrolyte consisting of succinonitrile (SN) and poly (ethylene glycol) methyl ether acrylate (PEGMEA) is developed. The research results demonstrate that the interactions between SN and PEGMEA promote the dissociation of the lithium difluoro(oxalato) borate (LiDFOB) salt and increase the concentration of free Li+. The well‐designed eutectic‐based PAN1.2‐SPE (PEGMEA: SN=1: 1.2 mass ratio) exhibits high ionic conductivity of 1.30 mS cm−1 at 30 °C and superior interface stability with Li anode. The Li/Li symmetric cell based on PAN1.2‐SPE enables long‐term plating/stripping at 0.3 and 0.5 mA cm−2, and the Li/LiFePO4 cell achieves superior long‐term cycling stability (capacity retention of 80.3 % after 1500 cycles). Moreover, Li/LiFePO4 and Li/LiNi0.6Co0.2Mn0.2O2 pouch cells employing PAN1.2‐SPE demonstrate excellent cycling and safety characteristics. This study presents a new pathway for designing high‐performance polymer electrolytes and promotes the practical application of high‐stable lithium metal batteries.

“…[ 7 ] Considering the need for continuous processability in large‐scale applications, [ 8 ] a promising strategy is to use cheap and easy‐to‐obtain polymers such as polyethylene oxide (PEO). [ 9 ] Furthermore, filler modification can be used to simultaneously improve ionic diffusivity, mechanical properties, electrochemical properties, and thermal stability.

Polymers are promising candidates as solid‐state electrolytes due to their performance and processability, but fillers play a critical role in adjusting the polymer network structure and electrochemical, thermal, and mechanical properties. Most fillers studied so far are anisotropic, limiting the possibility of homogeneous ion transport. Here, applying metal‐organic framework (MOF) glass as an isotropic functional filler, solid‐state polyethylene oxide (PEO) electrolytes are prepared. Calorimetric and diffusion kinetics tests show that the MOF glass addition reduces the glass transition temperature of the polymer phase, improving the mobility of the polymer chains, and thereby facilitating lithium (Li) ion transport. By also incorporating the lithium salt and ionic liquid (IL), Li–Li symmetric cell tests of the PEO‐lithium salt‐MOF glass‐IL electrolyte reveal low overpotential, indicating low interfacial impedance. Simulations show that the isotropic structure of the MOF glass facilitates the wettability of the IL by enhancing interfacial interactions, leading to a less confined IL structure that promotes Li‐ion mobility. Finally, the obtained electrolyte is used to construct Li–lithium iron phosphate full batteries that feature high cycle stability and rate capability. This work therefore demonstrates how an isotropic functional filler can be used to enhance the electrochemical performance of solid‐state polymer electrolytes.
