This study focuses on a series of 2D MPS3 materials containing different transition metal elements (M = Mn, Fe, Co, and Ni) synthesized by the chemical vapor transport method. In-depth theoretical analysis employing density functional theory combined with crystal orbital Hamilton population reveals that NiPS3 exhibits the lowest Na+ diffusion barrier and the strongest Na+ adsorption capability among the four materials. And these exceptional characteristics originate from the distinctive low-spin electronic configuration inherent in NiPS3, triggering a pronounced electronic repulsion between bridging Ni and S atoms, consequently diminishing the strength of Ni-S bonds and substantially enhancing the electrochemical reactivity. Furthermore, the S element in NiPS3 exhibits a highest p-band center energy level in the four samples, resulting in a corresponding decrease in the occupancy of the Na-S antibonding sigma orbital, which in turn strengthens the interaction between S and Na+. This enhanced interaction significantly improves the adsorption capability of NiPS3 towards Na+, effectively facilitating the charge transfer at the interface. Electrochemical test results indicate that NiPS3 exhibits the most superior electrochemical performance among the four materials, maintaining a specific capacity of 500.7 mA h g−1 after 1100 cycles at 5 A g−1. This study, through the profound integration of theory and experiments, fundamentally elucidates and verifies the underlying reasons for the superior properties of NiPS3 in MPS3 anodes.","PeriodicalId":306,"journal":{"name":"Energy Storage Materials","volume":"49 1","pages":""},"PeriodicalIF":20.4,"publicationDate":"2025-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142990305","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Specifically, an inorganic-rich CEI/SEI layer induced by CBDA (a DPA featuring a quaternary ring spatial linking structure) exhibits superior Li+ interfacial kinetics and an ultra-stable cycle performance, outperforming the other systems. As a result, the NCM811ǁLi cells containing CBDA show excellent long-term performances, even under high voltage, high load, and high charge-discharge current density, respectively. The coin-cell using a low-loading cathode exhibits 129 mAh g-1 discharged capacity for over 200 cycles at a 6 C rate. Moreover, The high-loading cathode retains 80% capacity after 312 cycles at 1.0 C. Furthermore, the NCM811ǁLi pouch cell demonstrated a capacity retention rate of 99.8% after 50 cycles. Prolonged stable cycling for 900 cycles (93% capacity retention) in an NCM811ǁGraphite pouch cell is enabled by CBDA.

Layered transition metal oxides are mainly used as cathode materials to enhance energy density and electrochemical performances. In this study, we compare Mn-based P2-type Na0.7Ni0.2Co0.2Mn0.6O2 (NCM) with partially Fe-substituted Na0.7Ni0.2Co0.2Mn0.5Fe0.1O2 (NCMF) via facile solid-state synthesis. Interestingly, Fe-substitution improves not only structural stability but also Na+ diffusion kinetics. It is found that the P2-O2 phase transition at high voltage region is mitigated with smaller volume change and enhanced oxygen redox reaction as demonstrated by in-situ X-ray diffraction and ex-situ X-ray photoelectron spectroscopy. In addition, density functional theory calculations exhibit that NCMF expedites Na+ diffusion and reduces the site energy difference between Naf and Nae by decreasing Na occupancy in the Naf site, which is located right below the transition metal ions. As a result, the NCMF electrode delivers a high initial energy density of 601.5 Wh kg-1 with an average discharge voltage of 3.05 V (V vs. Na+/Na). It also shows a high discharge capacity of 168.15 mAh g-1 at 0.5 C with excellent capacity retention of 68.7% after 100 cycles within a wide voltage range of 1.5-4.5 V.

However, the atomic-scale mechanism of phase transformations in metal halide perovskites during lithium storage process remains largely unexplored. Herein, the structural evolution of CsPbBr3 is comprehensively investigated through various in/ex-situ techniques, disclosing the generation of CsBr, LiBr, Pb, and Li22Pb5 phases via intercalation-conversion-alloying reactions during lithiation and the reversible formation of CsPbBr3 upon charging process. Furthermore, CsPbBr3 particles are embedded within conductive carbon nanotubes (o-CNT) to take full advantage of its negative fading phenomenon, which can deliver high specific capacities of 630 mA h g−1 at 0.1 A g−1 over 220 cycles and 376 mA h g−1 at 1.0 A g−1 at the 900th cycle. Comprehensive experimental and theoretical analysis identify that the upgraded negative fading of CsPbBr3 originates from the enhanced Li-alloying reaction of residual Pb metal loaded on o-CNT and the improved pseudocapacitive contribution from the reduced size of active material during cycles. Thus, this work not only uncovers the electrochemical (de)lithiation mechanism of CsPbBr3 but also proposes an effective strategy to boost the additional “negative fading” effect of halide perovskite materials for superior lithium storage performance.","PeriodicalId":306,"journal":{"name":"Energy Storage Materials","volume":"46 1","pages":""},"PeriodicalIF":20.4,"publicationDate":"2025-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142989006","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Urban mining, by recycling valuable metals from EOL batteries, can considerably reduce reliance on new raw materials by providing sustainable resources, thereby facilitating a cleaner energy transition. The research also emphasizes the importance of traceability and emerging innovations, such as the battery passport, which enhance transparency in the supply chain. Additionally, it explores the recycling industry's potential through techno-economic assessments to improve lithium-ion battery (LIB) recycling. Despite the challenges faced by different segments of the battery value chain, commercialization and technological advancements present promising opportunities for future development.

Specifically, COS molecules preferentially adsorb on the ZMA surface, where desolvated H2O from plating process can be immobilized by the multiple hydroxyl groups of COS. In addition, COS molecules capture hydrated Zn2+ through their amino groups, resulting in superior Zn2+ transport capability. Consequently, the introduction of COS into Zn(OTF)2 electrolyte enables a lower nucleation overpotential (358 mV) and activation energy (32.34 kJ mol-1) for plating.
