Special Issue Information

Dear Colleagues,

As Guest Editors, we are delighted to invite researchers worldwide to contribute to the second edition of “Novel Research on Electrochemical Energy Storage Materials”. As automobiles, consumer commodities, and other products are digitalized and electrified, the demand for energy storage devices with higher energy and power densities is becoming increasingly urgent; in recent years, electrochemical energy storage technologies have drawn more and more attention both in academia and industry. Inorganic materials comprise the majority of these devices, and they exert tremendous impacts on device performance. With this in mind, this Special Issue of Inorganics will focus on Novel Research on Electrochemical Energy Storage Materials. We invite you to submit manuscripts and publish your research in this Special Issue. 

This Special Issue aims to publish the latest research on inorganic materials for electrochemical energy storage applications, including the synthesis, characterization, and application of electrode active materials, conductive agents, binders, current collectors, electrolyte salts/solvents/additives, casing materials, separators, and other materials in various types of electrochemical energy storage devices, such as lithium/sodium (-ion) batteries, lead–acid batteries, redox flow batteries, and supercapacitor–battery hybrids.

In this Special Issue, original research articles, communications, and reviews are welcome. Research topics may include (but not limited to) the following: electrode active materials, conductive agents, binders, electrolyte salts/solvents/additives, and separators. Since our aim is to encourage researchers to publish their detailed experimental and theoretical results, there is no restriction on the maximum length of submissions.

We look forward to receiving your contributions.

With the rapid development of the photovoltaic industry, the issue of high-value conversion and utilization of end-of-life photovoltaic modules emerges. This study proposes using them in silicon-air batteries and designs a one-step pretreatment process to obtain two types of anode materials: AB@Si and TC@Si. Additionally, to enhance the electrochemical performance of retired crystalline silicon from PV modules as anodes for silicon-air batteries and improve their mass conversion efficiency, this study introduces Triton X-100 into the KOH electrolyte to inhibit chemical corrosion of the anodes and investigates the mechanism of action of Triton X-100. The results indicate that the surfaces of AB@Si and TC@Si exhibit a pyramidal structure, demonstrating excellent passivation resistance when used in silicon-air batteries, with maximum mass conversion efficiencies of 3.5% and 1.83%, respectively. Under the influence of Triton X-100, the maximum mass conversion efficiencies reach 6.39% and 3.09%, respectively. Polarization curves and mass loss under non-current conditions indicate that Triton X-100 primarily affects the chemical corrosion process of the silicon anode, while its impact on electrochemical corrosion is negligible. Results from contact angle measurements and adsorption energy calculations indicate that Triton X-100 adsorbs onto the silicon surface via benzene ring groups or OH groups, reducing hydrophilicity and delaying the self-corrosion process of silicon, thereby improving the battery′s discharge lifespan and mass conversion efficiency.

At present, lithium lanthanum zirconate (LLZO) is regarded as one of the most promising solid-state electrolyte materials due to its high ionic conductivity (about 10−3 S/cm at room temperature), high chemical stability, and excellent chemical stability toward cathode materials and lithium metal anodes. However, there are several problems, such as poor interface contact with the lithium metal anode resulting in high interface impedance, a high sintering densification temperature (usually >1200 °C), a complex preparation process, and high cost. In recent years, researchers have conducted extensive studies on LLZO and achieved remarkable progress and results. This paper systematically reviews the research progress of LLZO’s structural characteristics, conductive mechanism, preparation methods, improvement strategies, and so on. Full article

Thermal runaway (TR) remains a critical bottleneck for the safe application of lithium-ion battery (LIB) in large-scale energy storage systems, arising from the instability of battery materials under high temperatures. This review systematically summarizes materials design strategies to suppress TR, focusing on modifications of cathodes, anodes, separators, and electrolytes. For cathodes, surface coating and bulk doping enhance the structural stability and thermal decomposition temperature of high-Ni materials, while nanoscale engineering and carbon networks improve the electronic conductivity and interfacial stability of LiFePO4 (LFP). For anodes, surface modification of graphite suppresses solid-electrolyte interphase degradation, and nanostructured silicon-based composites mitigate thermal failure caused by volume expansion. Separator functionalization, including ceramic coating, inorganic separators, and thermal shutdown separators, enhances thermo-mechanical stability and enables thermally triggered ion blocking. Flame-retardant electrolytes incorporate phosphorus-based, organosilicon, and halogenated additives that act through combined gas- and condensed-phase mechanisms. The review further discusses challenges in interfacial compatibility, system integration, and trade-offs among multiple performance metrics. Future efforts should focus on integrating intrinsic thermal stability with smart safety functions to achieve both high energy density and inherent safety. This review provides a systematic reference for the design and industrialization of high-safety materials for LIBs. Full article

In recent years, silicon-based anodes have become a model of commercial success among various high-capacity electrode materials. They also offer a promising substitute for the lithium metal anode (LMA) in lithium–air batteries (LABs), which have the highest specific energy. However, the poor air stability of lithiated silicon-based anodes makes pre-lithiation considerably more difficult and costly in mass production to improve their initial Coulombic efficiency and cyclability, which complicates their material design and electrode manufacturing. To address this issue, intensified efforts have been devoted in recent years, mainly by constructing encapsulation structures, such as core–shell, pomegranate-like or peapod-like architectures. These designs have achieved significantly boosted stability in dry air and, in some cases, even under prolonged exposure to ambient humidity. On the other hand, it was found that silicon-based anodes often provide better cyclic stability than LMAs in LABs and lithium–oxygen batteries (LOBs); however, in most cases, the silicon-based anodes were not optimized for air stability. This review summarizes the relevant works on improving the air stability of silicon-based anodes and LABs/LOBs that used a silicon-based anode, intending to shed light on future development of air-stable silicon-based anodes and bridge the gap between the electrodes’ air-stability and their application in LABs/LOBs.

All-solid-state lithium batteries (ASSLBs) are widely regarded as a promising next-generation energy-storage technology because they offer the potential to simultaneously improve the safety and energy density of conventional lithium battery systems. Among various solid electrolytes, Li-argyrodite sulfide electrolytes (Li6PS5X, X = Cl, Br, I) have attracted considerable attention owing to their high room-temperature ionic conductivity, good mechanical deformability, and favorable cost-effectiveness. However, for the practical deployment of Li-argyrodite sulfide electrolytes in ASSLBs, several critical challenges still need to be addressed, including limited synthesis strategies, insufficient air stability, and poor interfacial compatibility with both cathodes and anodes. This review summarizes recent advances in Li-argyrodite sulfide electrolytes from fundamental understanding to practical applications. The crystal structure characteristics and Li+ conduction mechanisms are first discussed to elucidate the origins of fast ion transport, followed by an overview of major synthesis strategies. Strategies for improving ionic conductivity, air stability, and electrode interfacial compatibility through compositional engineering and interfacial regulation are also highlighted. Finally, the prospects of Li-argyrodite sulfide electrolytes for practical all-solid-state batteries are discussed, together with the remaining challenges and future research directions. Full article
