Summary: Proton conducting polymer blend electrolytes based on cornstarch and PVP with NH4Br were prepared by solution casting technique. The addition of NH4Br enhanced the amorphous nature of the blend confirmed by XRD, and caused changes in peak intensity, peak shape, and position in FTIR, indicating complex formation between the polymer and salt. The highest conductivity was observed in the 30 wt.% NH4Br added system at 358 K. The conduction mechanism involves quantum mechanical tunneling at mid-frequency and large polaron tunneling at higher frequency.

Summary: The study presents an expert-curated dataset of lithium ion conductors and their associated conductivities. The dataset contains 820 entries collected from 214 sources, including chemical composition, structural label, and ionic conductivity at specific temperatures. Unsupervised machine learning and the Element Movers Distance were used to analyze the materials in the context of compounds from an inorganic crystal structure database. A CrabNet-based classifier was trained using this dataset to estimate the ionic conductivity of chemical compositions. This classifier serves as a practical tool for experimentalists in prioritizing candidates for further investigation as lithium ion conductors.

Summary: Conducting polymers are used in various electrochemical devices, and a treatment method can enhance both electronic and ionic conductivity. The charging speed of conducting polymer supercapacitors with electrode thickness of 4.7 μm is increased by 40 times through this treatment. It also increases volumetric capacitance and may be attributed to the removal of insulating material to form an open polymer structure.

Summary: Controlling Li ion transport in glasses is crucial for developing all-solid-state batteries. Li3PS4 glass, a solid electrolyte candidate, shows a dynamic coupling effect between Li+ cation mobility and PS43- anion libration, known as the paddlewheel effect. Additionally, it exhibits a coordinated cation diffusion effect (cation-cation interactions) that enhances Li ion transport. The correlation between Li+ ions in the glass structure can be determined by evaluating their valence oscillations, providing insights for the development of new solid electrolytes.

Summary: Single-ion conductive polymer electrolytes (SICPEs) with a high cationic transference number have advantages in solid-state batteries (SSBs), but face challenges in terms of inferior ionic conductivity at room temperature. This review discusses recent advancements in improving ambient ionic conductivity in order to develop solid polymer electrolytes for SSBs. Strategies such as delocalizing charges in polyanions, designing highly conductive polymer matrices, and utilizing synergistic effects in SICPEs are highlighted.

Summary: A rock-salt-structured Li-conducting high entropy oxide was prepared and used as an active filler in a PEO-based solid-state composite electrolyte. The study demonstrated that the high entropy oxide significantly improved the ionic conductivity of the composite membrane and reduced its activation energy. The Li||Li symmetric batteries and Li||LiFePO4 full batteries with the high entropy oxide showed excellent rate performance at different temperatures and rates, suggesting its superiority as an active filler. This research contributes to the development of all-solid-state batteries at lower temperatures.
