Summary: The study investigated the integrated Cr and S poisoning of LSCF cathodes in solid oxide fuel cells, showing that such poisoning can lead to increased polarization and ohmic resistance, resulting in performance degradation of the cell. The degradation phenomenon caused by integrated Cr and S deposition was found to be more severe, indicating its higher unpredictability.

Summary: The garnet-type phase Li7La3Zr2O12 (LLZO) is a promising oxide solid electrolyte for solid-state batteries (SSBs). This perspective article focuses on the challenges of integrating LLZO into composite cathodes and discusses the critical issues needed to achieve all-solid-state LLZO-based batteries with enhanced safety and performance. The insights gained from a comprehensive literature survey of LLZO-cathode interfaces are used to guide the development of LLZO-based SSBs.

Summary: To achieve safe and high energy density solid-state batteries (SSBs), minimizing the weight of solid-state electrolyte (SSE) and using a high voltage and high specific capacity cathode are crucial. An ultra-thin blending polymer electrolyte (BPE) is designed by blending PEO, PMMA, and PVDF-HFP, and complexing with SN, FEC, and LiTFSI plasticizers. The BPE shows superior performance in terms of capacity retention, stability, and Coulombic efficiency, indicating its promising application in high energy density quasi-solid-state batteries (QSSBs).

Summary: Na4P2S7-6xO4.62xN0.92x (NaPSON) glassy solid electrolytes (GSEs) were studied for their electrochemical properties and processability into thin films. The x = 0.2 composition (NaPSON-2) showed high conductivity, non-crystallizability, stability against Na-metal, and support for symmetric cell cycling. Thin films of NaPSON-2 exhibited unchanged conductivity and slow growth in resistance, while NaPSON-2 disc displayed stability and reaction products in the bulk. The surface stability was attributed to the segregation of trigonally coordinated nitrogen.

Summary: This study investigates the effects of perovskite-structured Pr0.4Sr0.6Co0.2Fe0.8O3-delta (PSCF) modification on the electrochemical performance of La1-xSrxCo1-yFeyO3-delta (LSCF) cathodes using experimental and theoretical methods. The results show that PSCF modification reduces the formation energies of oxygen vacancies, lowers the adsorption energies of oxygen adsorption on the LSCF surface, and greatly decreases the dissociation barriers of oxygen molecules on the LSCF surface. These changes result in a significant improvement in the rate of oxygen reduction reaction and the activation of the LSCF surface with PSCF modification, leading to enhanced performance of the cathode.

Summary: In this study, a freestanding sulfide solid electrolyte film was fabricated using PTFE and Li6PS5Cl powders through hot rolling technology, with a thickness of 40 μm and high ionic conductivity of 8.4 mS cm-1. A solvent-free cathode film (LiNbO3@LiNi0.6Co0.2Mn0.2O2) was also prepared using dry method technology. The all-solid-state batteries with these materials exhibited high discharge capacity (120 mA h g-1) and stability (86.4% retention after 1000 cycles at 1C), as well as excellent rate performance (40 mA h g-1 at 4C) at room temperature. These findings demonstrate the potential commercial applications of sulfide-based solid-state batteries.

Summary: In this study, a method for producing a thin, mechanically robust, sodium-ion conducting composite solid electrolyte (CSE) was reported. This was achieved by infiltrating the monomers of polyethylene glycol diacrylate (PEGDA) and polyethylene glycol (PEG) and either NaClO4 or NaFSI salt into a silica-based glass-fiber matrix and initiating in situ polymerization. The fabricated CSEs showed high loadings of PEG as a plasticizer to enhance ionic conductivity, and the use of NaFSI salt promoted stable stripping and plating in a symmetric cell.
