Enhancing Li-ion conduction and mechanical properties via addition of fluorine-containing metal—organic frameworks in all-solid-state cross-linked hyperbranched polymer electrolytes

Highly Efficient Hydrosilylation of Ethyne over Pt/ZrO2 Catalysts with Size-Dependent Metal–Support Interactions

“…All the samples show the characteristic diffraction peaks at 2θ = 24.4, 28.2, 31.5, 34.2, 49.3, and 50.1°, which are assigned to the (011), (−111), (111), (200), (220), and (022) planes of monoclinic ZrO 2 (JCPDS no. 37-1484), − respectively. There are no detectable diffraction peaks for metallic Pt or oxide species, implying that Pt species of Pt/ZrO 2 are highly dispersed on the ZrO 2 support.…”

Poly(ethylene oxide)‐Based Composite Electrolyte with Lithium‐Doped High‐Entropy Oxide Ceramic Enabled Robust Solid‐State Lithium‐Metal Batteries

“…LSV was conducted to measure electrochemical stability windows of SSEs based on Li j j SS cells. [48][49][50][51][52] During the oxidation process from 2.8 V to 6.0 V, the first apparent current increment for the cell occurred at 4.10 V with the SPE-PEO electrolyte while at 4.85 V using the CSE-Li 0.25 HEO electrolyte, indicating that CSE-Li 0.25 HEO possessed a higher electrochemical oxidation window, matchable to high-voltage cathodes. Compared to SPE-PEO, the Lewis acid-base interactions between metal sites of Li 0.25 HEO and EO segments of PEO can improve the electronic transfer capability of the polymer chain, thus alleviating the polarization and enhancing the antioxidation performance.…”

Architectural design and electrochemical performance of MOF‐based solid‐state electrolytes for high‐performance secondary batteries

“…A membrane can be obtained after the evaporation of the solvent and excessive liquid electrolyte can be further removed through pressing at 200 MPa. Similarly, Wen et al [ 65 ] designed across‐linked network polyethylene glycol (PEG)–hyperbranched poly(ethyleneimine) (HPEI) as polymer substrate, then added the mixed solution of UIO‐66‐(F) and methanol, the SSE can be obtained after the solvent evaporation and vacuum for 24 h. In this method, volatile polar solvents and appropriate polymers are often selected to strengthen the connection of MOFs and polymer substrates, so that the transference of ions can be accelerated and the stability of SSEs can be enhanced. (2) Through the modification after synthesis, the polymer monomer was chemically grafted onto MOF nanoparticles and further photopolymerized into a film.…”

“…Except for the enhancement of ionic conductivity, an appropriate design can alleviate the aggregation of MOFs fillers. Wen et al [ 65 ] designed cross‐linked hyperbranched polymer electrolyte composed of aldehyde‐terminated PEG and HPEI for SSLIBs. When UIO‐66 and LiTFSI were added into the composite polymer matrix, the CSPE can show considerable enhancement of Li + transference number from 0.23 to 0.54.…”
