“…The electrochemical behavior of the heterostructured FeSe 2 /MoS 2 as the cathode for AIBs is investigated by CV tests between 0.01 and 1.8 V (Figure a). In the first cycle, the sharp reduction and oxidation peaks distinguished from the latter cycles represent the solid electrolyte interface (SEI) formation and the irreversible consumption of electrolytes. , In the following scanning, the little change in CV profiles indicated that the electrochemical reaction of the heterostructured FeSe 2 /MoS 2 is highly reversible. Meanwhile, the reduction peak at 0.3 V and two oxidation peaks around 1.1 and 1.2 V imply the intercalation and extraction reaction of Al 3+ , respectively. , In addition, the reduction peak appearing in the discharge process of the first circle is presumed to be the reduction reaction of a small amount of Fe or Mo dissolved in the electrolyte, which has been proved by the reported literature. − Figure b compares the cycling performance of the heterostructured FeSe 2 /MoS 2 and FeSe 2 /MoS 2 mixture of machinery at 1.0 A g –1 to demonstrate the superiority of interfacial engineering.…”

The affordable and high-capacity aluminum-ion batteries (AIBs) are potential candidates for energy-storage systems. Nevertheless, traditional transition-metal chalcogenide (TMC) cathodes encounter severe capacity decay and sluggish reaction kinetics, impeding the development of AIBs. Herein, we have prepared the heterostructured FeSe2/MoS2 nanoflowers as the cathodes for AIBs. The construction of the built-in electric field in the interface of two phases plays an important role in realizing rapid charge transport, stable structure, and increased reversible capacity. As a result, the heterostructured FeSe2/MoS2 nanoflowers cathodes deliver an outstanding discharge capacity of 222 mAh g–1 at 0.5 A g–1 and an excellent cycling stability of 116 mAh g–1 over 140 cycles at 1.0 A g–1. These works provide a versatile strategy for further boosting the electrochemical performance of AIBs.

“…It separates the anode and cathode to prevent direct contact, enabling electron flow in the external circuit. In alkaline metal and metal-ion batteries, dendrites formed at the electrode surface can cause internal short-circuiting, resulting in serious safety issues such as thermal runaway, gas generation, and explosion [3,[50][51][52][53]. Polyolefin-based membranes (i.e., PP, PE) are broadly used in the battery industry owing to their excellent mechanical strength and electrochemical stability [54].…”

This review discusses important scientific progress, problems, and prospects of lignin-based materials in the field of rechargeable batteries. Lignin, a component of the secondary cell wall, is considered a promising source of biomass. Compared to cellulose, which is the most extensively studied biomass material, lignin has a competitive price and a variety of functional groups leading to broad utilization such as adhesive, emulsifier, pesticides, polymer composite, carbon precursor, etc. The lignin-based materials can also be applied to various components in rechargeable batteries such as the binder, separator, electrolyte, anode, and cathode. This review describes how lignin-based materials are adopted in these five components with specific examples and explains why lignin is attractive in each case. The electrochemical behaviors including charge–discharge profiles, cyclability, and rate performance are discussed between lignin-based materials and materials without lignin. Finally, current limitations and future prospects are categorized to provide design guidelines for advanced lignin-based materials.

Growth Mechanism of Micro/Nano Metal Dendrites and Cumulative Strategies for Countering Its Impacts in Metal Ion Batteries: A Review

Metal-ion batteries are capable of delivering high energy density with a longer lifespan. However, they are subject to several issues limiting their utilization. One critical impediment is the budding and extension of solid protuberances on the anodic surface, which hinders the cell functionalities. These protuberances expand continuously during the cyclic processes, extending through the separator sheath and leading to electrical shorting. The progression of a protrusion relies on a number of in situ and ex situ factors that can be evaluated theoretically through modeling or via laboratory experimentation. However, it is essential to identify the dynamics and mechanism of protrusion outgrowth. This review article explores recent advances in alleviating metal dendrites in battery systems, specifically alkali metals. In detail, we address the challenges associated with battery breakdown, including the underlying mechanism of dendrite generation and swelling. We discuss the feasible solutions to mitigate the dendrites, as well as their pros and cons, highlighting future research directions. It is of great importance to analyze dendrite suppression within a pragmatic framework with synergy in order to discover a unique solution to ensure the viability of present (Li) and future-generation batteries (Na and K) for commercial use.
