“…[7][8][9][10][11][12] Another critical issue, which has become a major focus in recent research, is the sluggish redox kinetics between various sulfur species during charge-discharge cycling, limiting the cycling stability and rate performance of Li-S batteries. [13][14][15] To address the aforementioned issues, various materials have been developed and applied as sulfur hosts in Li-S batteries, including carbon matrix materials, [16][17][18] metal oxides/nitrides/sulfides, [19][20][21][22] MXenes and metal-organic frameworks (MOFs). [23,24] Although these efforts improve the electrochemical performance of Li-S batteries to some extent, most of such research predominantly focused on enhancing the electrocatalytic activity with the aid of component adjustment, morphologic optimization, and electronic modulation of the bulk phase.…”

Elaborate modulation of the highly active crystal facet emerges as an efficient strategy for enhancing the nanocrystalline catalytic activity. Herein, ultrathin TiB2 nanosheets with preferentially exposed (1‐10) facets are developed as highly efficient catalyst with enriched bonding and electrocatalytic sites in Li‐S batteries. Attributed to the highly equivalent exposure of Ti and B active sites on the (1‐10) surface, the (1‐10) facet‐dominated TiB2 nanosheets maximize the binding effect via Ti and B dual‐atom‐sites adsorption through Ti─S and B─S bonds. More importantly, experiments and theoretical calculations confirm the superb catalytic activity of (1‐10)TiB2 in facilitating the polysulfide conversion and Li2S decomposition, thereby markedly suppressing the shuttling effect and improving the redox kinetics. Consequently, excellent electrochemical properties are achieved in Li‐S batteries, which demonstrate a high discharge capacity of 1469 mAh g−1 at 0.2 C and maintain high capacity reversibility at 1 C with a low capacity decay rate of 0.048% over 500 cycles. Even under a sulfur loading of 5 mg cm−2, a prominent areal capacity of 4.86 mAh cm−2 is still attained. It is proposed that the crystal surface engineering provides a new path for the structure optimization of sulfur catalysts in Li‐S batteries.

As global energy priorities shift toward sustainable alternatives, the need for innovative energy storage solutions becomes increasingly crucial. In this landscape, solid-state batteries (SSBs) emerge as a leading contender, offering a significant upgrade over conventional lithium-ion batteries in terms of energy density, safety, and lifespan. This review provides a thorough exploration of SSBs, with a focus on both traditional and emerging cathode materials like lithium cobalt oxide (LiCoO2), lithium manganese oxide (LiMn2O4), lithium iron phosphate (LiFePO4), as well as novel sulfides and oxides. The compatibility of these materials with solid electrolytes and their respective benefits and limitations are extensively discussed. The review delves into the structural optimization of cathode materials, covering strategies such as nanostructuring, surface coatings, and composite formulations. These are critical in addressing issues like conductivity limitations and structural vulnerabilities. We also scrutinize the essential roles of electrical and thermal properties in maintaining battery safety and performance. To conclude, our analysis highlights the revolutionary role of SSBs in the future of energy storage. While substantial advancements have been made, the path forward presents numerous challenges and research opportunities. This review not only acknowledges these challenges, but also points out the need for scalable manufacturing approaches and a deeper understanding of electrode–electrolyte interactions. It aims to steer the scientific community toward addressing these challenges and advancing the field of SSBs, thereby contributing significantly to the development of environmentally friendly energy solutions.

“…This means that during the battery's operation, the Mo6S8 nanosheets can dynamically enhance their ionic conductivity by undergoing a reversible process of lithium-ion intercalation, forming LixMo6S8. This dynamic enhancement suppresses the undesirable shuttling effect and accelerates the conversion kinetics, leading to superior battery performance in terms of cycling stability, high-rate capability, and lowtemperature performance [50].…”

As the global community shifts away from fossil fuels towards more environmentally friendly energy alternatives, there is an escalating demand for sophisticated energy storage solutions. Solid-State Batteries (SSBs) have emerged as a promising advancement, presenting a superior substitute to conventional lithium-ion batteries. This review provides an in-depth examination of SSBs, emphasizing their enhanced energy density, safety, and longevity. We evaluate conventional cathode materials, including lithium cobalt oxide (LiCoO2), lithium manganese oxide (LiMn2O4), and lithium iron phosphate (LiFePO4). Additionally, we introduce emerging materials such as sulfides, oxides, and air-based cathodes, discussing their benefits, limitations, and their congruence with solid electrolytes. Special attention is devoted to the structural fine-tuning of cathode ma-terials, investigating approaches like nanostructuring, surface coatings, and composite strategies to counteract issues such as restricted conductivity and structural volatility. The review critically analyzes the electrical and thermal properties of these materials, which are essential for battery safety and efficacy. Moreover, we present a comparative assessment of cathode materials based on performance indicators and identify prevailing research voids and hurdles in the commerciali-zation of SSB cathodes. Concluding, we suggest prospective research directions and innovations, underscoring the revolutionary potential of SSB technologies in paving the way for a sustainable energy horizon.
