Special Issue Information

Dear Colleagues,

Rechargeable batteries, ranging from small portable devices to large energy storage systems, have emerged as indispensable electrochemical devices in our daily lives. The three primary components of rechargeable cells are the positive and negative electrodes and the electrolytes. Nanotechnologies are positioned to play a critical role in significantly improving battery performance. The rational design of various nanomaterials has been a major research theme in the process of developing high-performance batteries. Although nanomaterials may face a higher risk of unwanted secondary reactions than bulk materials, a suitable material design can overcome this issue while providing beneficial opportunities. For example, suitably designed nanomaterials may provide a significant increase in the effective surface area of electrodes, thereby increasing the energy storage. Moreover, the judicious design of nanoarchitecture can boost the diffusion of ions into the electrodes, resulting in the enhancement of the electrochemical reaction kinetics.

Among various types of rechargeable batteries, Li-ion batteries are presently regarded as market-leading technologies thanks to their many beneficial features. However, Li-ion batteries still have limitations to be overcome, and thus there is ongoing research into several different types of potential next-generation batteries.

This Special Issue of Nanomaterials will cover the advancements in recent nanotechnologies and nanomaterials for various ion batteries (Li-ion batteries, sodium-ion batteries, Li–sulfur batteries, multivalent ion batteries, aqueous batteries, etc.). The development of new functional nanomaterials, as important components in these batteries, is the central topic to be discussed in this Special Issue.

Metallic phase 1T MoS2 is a well-known potential anode for enhancing the electrochemical performance of lithium-ion batteries owing to its mechanical/chemical stability and high conductivity.

Metallic phase 1T MoS2 is a well-known potential anode for enhancing the electrochemical performance of lithium-ion batteries owing to its mechanical/chemical stability and high conductivity. However, during the lithiation/delithiation process, MoS2 nanosheets (NSs) tend to restack to form bulky structures that deteriorate the cycling performance of bare MoS2 anodes. In this study, we prepared Ag nanoparticle (NP)-decorated 1T MoS2 NSs via a liquid exfoliation method with lithium intercalation and simple reduction of AgNO3 in NaBH4. Ag NPs were uniformly distributed on the MoS2 surface with the assistance of 3-mercapto propionic acid. Ag NPs with the size of a few nanometers enhanced the conductivity of the MoS2 NS and improved the electrochemical performance of the MoS2 anode. Specifically, the anode designated as [email protected]2 (prepared with AgNO3 and MoS2 in a weight ratio of 1:10) exhibited the best cycling performance and delivered a reversible specific capacity of 510 mAh·g−1 (approximately 73% of the initial capacity) after 100 cycles. Moreover, the rate performance of this sample had a remarkable recovery capacity of ~100% when the current decreased from 1 to 0.1 A·g−1. The results indicate that the Ag nanoparticle-decorated 1T MoS2 can be employed as a high-rate capacity anode in lithium-ion storage applications. Full article

SnO2 nanoparticles (NPs) have been used as reversible high-capacity anode materials in lithium-ion batteries, with reversible capacities reaching 740 mAh·g−1. However, large SnO2 NPs do not perform well in charge–discharge cycling. In this work, we report the incorporation of MoS2 nanosheet (NS) layers with SnO2 NPs. SnO2 NPs of ~5 nm in diameter synthesized by a facile hydrothermal precipitation method. Meanwhile, MoS2 NSs of a few hundreds of nanometers to a few micrometers in lateral size were produced by top-down chemical exfoliation. The self-assembly of the MoS2 NS layer on the gas–liquid interface was first demonstrated to achieve up to 80% coverage of the SnO2 NP anode surface. The electrochemical properties of the pure SnO2 NPs and MoS2-covered SnO2 NP anodes were investigated. The results showed that the SnO2 electrode with a single-layer MoS2 NS film exhibited better electrochemical performance than the pure SnO2 anode in lithium storage applications. Full article

Among the various types of polymer electrolytes, gel polymer electrolytes have been considered as promising electrolytes for high-performance lithium and non-lithium batteries. The introduction of inorganic fillers into the polymer-salt system of gel polymer electrolytes has emerged as an effective strategy to achieve high ionic conductivity and excellent interfacial contact with the electrode. In this review, the detailed roles of inorganic fillers in composite gel polymer electrolytes are presented based on their physical and electrochemical properties in lithium and non-lithium polymer batteries. First, we summarize the historical developments of gel polymer electrolytes. Then, a list of detailed fillers applied in gel polymer electrolytes is presented. Possible mechanisms of conductivity enhancement by the addition of inorganic fillers are discussed for each inorganic filler. Subsequently, inorganic filler/polymer composite electrolytes studied for use in various battery systems, including Li-, Na-, Mg-, and Zn-ion batteries, are discussed. Finally, the future perspectives and requirements of the current composite gel polymer electrolyte technologies are highlighted. Full article
