Summary: The electro-chemomechanical behavior of microsized Sn anodes during charge/discharge was investigated, and it was found that electrolyte composition plays a critical role in the parasitic reactions and sodiation/de-sodiation reversibility. Ether-based electrolytes enabled the formation of inorganic species dominated solid-electrolyte interphase (SEI) with improved mechanical strength, leading to higher specific capacity and improved cycling stability.

Summary: In this study, a polymer additive called PAMMA was used as a sacrificial agent, which was found to promote the formation of a dense and Li3N-rich SEI film on the Li-metal surface in Li-O-2 batteries. This additive effectively suppressed the shuttle effect from harmful species, leading to improved cycling performance and protection of Li-metal.

Summary: The electrochemical properties of micron In-Sn-Bi alloy electrodes for rechargeable magnesium batteries (RMBs) were evaluated. The In-Sn-Bi alloy anodes showed high reversible specific capacity and cycle stability, compared to the low stability pure Bi anodes. Among the studied alloys, the In10Sn10Bi80 electrode exhibited a reversible specific capacity of up to 260 mAh g(-1), good rate performance, and excellent cycle stability. The multi-phase and fine-substructure design of the electrode materials holds promise for RMB applications.

Summary: Alkali ion batteries have gained significant attention due to their high power and energy density. However, there is a need for novel electrode materials with higher capacity and longer cycle life. Carbon-supported single-atom metal (CSAM) materials show promise in increasing the anode capacity and extending its lifespan, but more research is required. This mini-review summarizes the application and work mechanisms of CSAM materials in alkali ion batteries, discusses their disadvantages, and proposes solution strategies.

Summary: The solid molten salt-Fe2O3@Polypyrrole (SMS-Fe2O3@PPy) materials have been successfully synthesized and applied as anode electrode for lithium-ion batteries (LIBs) through a two-step method. The SMS-Fe2O3@PPy electrode consists of Fe-based solid molten salt (SMS), PPy, and octahedral Fe2O3 nanoparticles. The introduction of PPy not only provides a coating to suppress volume expansion but also improves the electrical conductivity, effectively reducing the volume expansion during Li+ insertion/extraction. The SMS-Fe2O3@PPy electrode exhibits excellent electrochemical performance, including high reversible capacities, good cycle stability, and excellent rate performance.

Summary: Magnesium rechargeable batteries (MRBs) are attracting attention due to their low cost, high safety, and high theoretical volumetric capacity. The use of eutectic and hypereutectic Mg-Sn alloys as anodes for MRBs was explored. The alloys exhibited unique microstructures and the dissolution processes were studied in an all-phenyl-complex (APC) electrolyte. Hypereutectic alloys showed better battery performance due to their superior mechanical properties.
