Summary: M-SO2 batteries have promising applicability and the nonflammability of SO2-based electrolytes is an exciting feature. Primary LSBs and secondary LSBs and NSBs have been extensively studied. They are more attractive than metal-air batteries due to lower charge polarization and higher cell voltage. However, there are still challenges that need to be addressed for further improvement.

Summary: Thin films of solid-state polymer electrolytes (SSPEs) have been developed for dye-sensitized solar cells (DSCs) for the first time. Gel-electrolytes are prepared by utilizing a blend of poly(ethylene oxide) (PEO)/polyethylene glycol (PEG) and an acetonitrile-based iodide liquid electrolyte, and then cast onto a glass substrate to fabricate solvent-free SSPEs by evaporating the solvent. The SSPE films are sandwiched between photoelectrodes and counter electrodes to assemble the solid-state DSCs, and the PCE can be improved by introducing TiO2 nanofillers in the SSPEs. The high stability of the solid-state DSCs is demonstrated with a retention of 98% of their original efficiency after a 700-hour test period.

Summary: A Li-rich Mn-based layered oxide cathode (LLO) is a promising cathode material for high-energy lithium-ion batteries. However, it faces challenges such as sluggish kinetics, oxygen evolution, and structural degradation. In this study, an interfacial optimization of primary particles is proposed to improve ion and electron transport simultaneously. The modified interface containing AlPO4 and carbon enhances Li+ diffusion and reduces charge-transfer resistance, leading to improved charge-transport kinetics. The optimized LLO cathode exhibits a high initial Coulombic efficiency of 87.3% and superior high-rate stability with 88.2% capacity retention after 300 cycles at a 5C high rate.

Summary: A detailed picture of temperature dependent behavior of Cs(x)FA(1-x)PbI(3) perovskite quantum dots is constructed by in situ optical spectroscopic and structural measurements. The thermal degradation mechanism depends on both the exact chemical composition and the ligand binding energy. Cs-rich quantum dots undergo a phase transition from black gamma-phase to yellow delta-phase, while FA-rich quantum dots directly decompose into PbI2. Quantum dot growth is observed at elevated temperatures. FA-rich quantum dots exhibit stronger electron-longitudinal optical phonon coupling, leading to a higher probability of exciton dissociation compared to Cs-rich quantum dots. Surface ligand-induced strain enables full-range A-site tuning.
