Summary: In this study, a heterostructure of CeO2@(Ni, Co)(3)S-4 was synthesized by assembling one-dimensional nanorods and nanosheets derived from a metal-organic framework (MOF). The CeO2@(Ni, Co)(3)S-4 heterostructure exhibited a high specific capacitance, outstanding rate performance, and excellent cycling stability. The impressive electrochemical performance of the electrode material can be attributed to the large electroactive surface area and rapid electron transfer pathways provided by the CeO2 nanorods, the strong electronic interaction between CeO2 and (Ni, Co)(3)S-4, the abundant oxygen vacancies promoting electronic conductivity and OH-capture, and the robust mechanic stability of the core-shelled structure.

Summary: Potassium (K) metal batteries have potential for commercial development, but the arbitrary dendrite growth and side reactions of K metal hinder their progress. Interface engineering between the current collector and K metal can improve the performance by guiding K metal deposition and suppressing side reactions. A bifunctional layer with an O/F-rich Sn-K alloy and a preformed solid-electrolyte interphase (SEI) layer has been designed to achieve this. The bifunctional layers enable low nucleation overpotential, high Coulombic efficiency, and stable operation of K metal batteries.

Summary: This study demonstrates the stable cycling of the SnS2-containing composite in KIBs by adopting dimethoxyethane (DME)-based electrolytes with a high K salt concentration. After optimizing the salt concentration in the DME-based electrolyte, the SnS2-containing composite achieves an enhanced reversible specific capacity and improved rate performance, indicating enhanced cycling stability. The decrease of free DME molecules in high salt concentration electrolytes suppresses the K-ion anisotropic aggregation and reduces side reactions, contributing to the homogeneous migration of K-ion and enhancement of cycling stability.

Summary: By reasonable structural design, a spherical glucose-derived carbon-regulated defect state Zn3V3O8 bimetallic oxide (CS@ZVO) cathode was synthesized. This design prevents the structural collapse during the cycle process, leading to a significant improvement in the cycle stability of aqueous zinc-ion batteries (AZIBs). The introduction of glucose-derived carbon can shift the valence state of vanadium in the ZVO bimetallic oxide cathode towards reduction, thereby significantly improving its zinc-ion storage capacity. The resulting CS@ZVO cathode exhibits a high discharge capacity of 154 mAh g(-1) at 1 A g(-1) after 100 cycles and a stable lifespan of 2000 cycles at 5 A g(-1).

Summary: Potassium-ion batteries (PIBs) are considered a promising alternative to lithium-ion batteries due to the abundance of potassium resources and low redox potential of potassium. Alloy-type anode materials have been extensively studied for PIBs due to their high theoretical capacities and abundant resources. However, the volume expansion effect during cycling significantly affects the cycling stability of alloy-type anodes. Various modification strategies, such as nanosized structure design and hybridization with conductive substrates, have been developed to address this challenge. In this review, the state-of-art progress and understanding of alloy-type anodes for PIBs, including K+ storage mechanism, electrochemical properties, and structure-property relationship, are summarized systematically.

Summary: This study investigates the relationship between the morphology of PMMA monopolymers and PMMA-PHEMA copolymers with the expected nature of surfactant-free microemulsions (SFMEs) before polymerization. It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
