Summary: Room temperature sodium-sulfur (Na-S) batteries are a promising energy storage system due to their high energy density and low cost. However, the use of organic liquid electrolytes in Na-S cells leads to issues such as polysulfide shuttling, uncontrollable Na dendrite growth, and safety concerns. Solid-state electrolytes have been proposed as a solution to these problems, but their practical application is still challenging due to poor interfacial compatibility and ionic conductivity issues. This paper provides a comprehensive review of solid-state Na-S batteries and discusses different types of solid-state electrolytes. The development of high-performance solid-state electrolytes is envisioned to improve the cycling stability of room temperature Na-S cells.

Summary: This study evaluated the toxicity of functional carbon nanodots (FCNs) to zebrafish through acute toxicity tests at the embryonic and adult stages. The results showed that FCNs and nitrogen-doped FCNs (N-FCNs) caused developmental retardation, cardiovascular toxicity, renal damage, and hepatotoxicity in zebrafish. The main reason for these effects was the oxidative damage induced by high doses of materials and the biodistribution of FCNs and N-FCNs in the fish. However, FCNs and N-FCNs also promoted the antioxidant activity in zebrafish tissues to counteract the oxidative stress. Both FCNs and N-FCNs were proven to be biosecure to zebrafish, with FCNs showing higher biosecurity due to their physicochemical properties. The effects of FCNs and N-FCNs on hatching rates, mortality rates, and developmental malformations were dose-dependent and time-dependent. The toxicity ratings of FCNs and N-FCNs were defined as practically nontoxic for zebrafish embryos, and FCNs were relatively harmless. These results confirm the biosecurity of FCNs-based materials for future practical applications.

Summary: This article presents the results of a systematic study on the electrochemical performance and mechanical changes in two types of commercial batteries with different anode chemistry. The study reveals that the swelling of anode layers in batteries with silicon-based components causes deformations in the jelly roll structure, but the presence of a small percentage of silicon does not significantly impact the cycling performance of the cells within the relevant state-of-health range for electric vehicles (EVs). The research suggests that there is room for improving the cell capacities by increasing the silicon loading in composite anodes to meet the increasing demands on EVs.

Summary: By coupling electrochemical testing to operando synchrotron based X-ray absorption and powder diffraction experiments, blended positive electrodes consisting of LiMn2O4 spinel (LMO) and layered LiNi0.5Mn0.3Co0.2O2 (NMC) were studied to understand their redox mechanism. It was found that blending NMC with LMO can enhance energy density at high rates, with the blend containing 25% LMO showing the best performance. Testing with a special electrochemical setup revealed that the effective current load on each blend component can vary significantly from the nominal rate and also changes with SoC. Operando studies allowed monitoring of the oxidation state evolution and changes in crystal structure, in line with the expected behavior of individual components considering their electrochemical current loads.
