“…One way to improve the performance of PEO-based electrolytes is to disperse inorganic fillers such as SiO 2 , TiO 2 , or Al 2 O 3 in the electrolyte [10][11][12]. Inorganic fillers have been reported to be able to (a) prevent the recrystallization of the polymer chains,and to (b) promote ionic mobility and ionic dissociation through Lewis acid-base interaction between filler and polymer or filler and ionic species [10,13,14].However, these effects may vary with the ionic conductor, the size and type of the filler, and the manufacturing conditions of the electrolyte.…”

“… In literature, the effect of ceramic fillers beyond reported improvements of mechanical properties is controversially discussed [38,62] . For Li‐SPEs, ceramic fillers were studied in a variety of different electrolyte salts for PEO‐LiX composite electrolytes (X=BETI, [62,63] TFSI [59,60,64] or triflate (SO 3 CF 3 − ) [39] ). The composition with an EO:Li molar ratio of 20 : 1 seemed particularly favoured, which is interesting from the perspective of its high degree of crystallinity of over 50 % [65] .…”

The low melting points of solid polymer electrolytes (SPEs) based on the KTFSI electrolyte salt allow comparatively low operation temperatures (below 50 °C) for K‐ion batteries, unlike their Li or Na counterparts. Unfortunately, for this reason the electrolyte is also rendered mechanically unsuitable in its function to act as a cell separator. Therefore, in this work the use of inorganic nanofillers (Al2O3 and SiO2) is explored with the aim to improve rheological, thermal and cation transport properties of the resulting polymer composite electrolytes. Their electrochemical properties were further examined in K‐metal symmetrical cells and K‐metal/SPE/K2Fe[Fe(CN)6] cells and compared to corresponding liquid electrolyte systems. As a result of particle‐polymer interactions, filler‐containing SPEs showed higher degrees of crystallinity combined with filler polymer interaction and thus improved mechanical integrity in the relevant temperature range of 25–55 °C, while maintaining similar ionic conductivities than a filler‐free sample above the melting temperature. Although plating‐stripping experiments in symmetrical cell setups suggested high cell resistances for various compositions and in some cases even rapid cell failure, Al2O3‐based SPEs generally displayed high capacity retention when cycled against a positive electrode (here Prussian blue analogue K2Fe[Fe(CN)6]) over 100–160 cycles and possibly beyond.

Herein, we synthesized a new polyethylene glycol (PEG)-based solid polymer electrolyte containing a rare earth oxide, CeO2, using mechanical metallurgy to prepare an encapsulation bonding material for MEMS. The effects of CeO2 content (0–15 wt.%) on the anodic bonding properties of the composites were investigated. Samples were analyzed and characterized by alternating current impedance spectroscopy, X-ray diffraction, scanning electron microscopy, differential scanning calorimetry, tensile strength tests, and anodic bonding experiments. CeO2 reduced the crystallinity of the material, promoted ion migration, increased the conductivity, increased the peak current of the bonding process, and increased the tensile strength. The maximum bonding efficiency and optimal bonding layer were obtained at 8 wt% CeO2. This study expands the applications of solid polymer electrolytes as encapsulation bonding materials.
