Summary: A localized saturated electrolyte (LSE) with 2-methyltetrahydrofuran (MeTHF) as an inner sheath solvent is proposed as a new electrolyte for Na-S batteries, which overcomes the challenges posed by the existing electrolytes and enables the development of dendrite-inhibited and shuttle-free Na-S batteries. The LSE features a low salt-to-solvent ratio and low diluent-to-solvent ratio, which expands the limit of localized high concentration electrolyte (LHCE). With this electrolyte, pouch cells with decent cycling performance under demanding conditions are demonstrated.

Summary: Rechargeable zinc-air batteries (ZABs) are promising alternatives to lithium-ion batteries due to their high energy density, safety, and low environmental impact. However, the catalytic performance of transitional metal phosphides (TMPs), especially Fe-based TMPs, needs improvement. In this study, a novel in situ etch-adsorption-phosphatization strategy was developed to fabricate a hollow FeP/Fe2P/Cu3P-N, P codoped carbon (Fe-P/Cu3P-NPC) catalyst for the cathode of liquid and flexible ZABs. The liquid ZABs showed a high peak power density of 158.5 mW cm(-2) and excellent long-term cycling performance (approximately 1100 cycles at 2 mA cm(-2)). Similarly, the flexible ZABs exhibited superior cycling stability of 81 hours at 2 mA cm(-2) without bending and 26 hours with various bending angles.

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.

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.
