Herein, phosphorus-doped porous hard carbon (HC@PC−P) were synthesized by the thermal polymerization of soy lecithin on the surfaces of hard carbon derived from olive kernels. The incorporation of heteroatom phosphorus in the porous hard carbon framework expands the carbon lattice spacing, optimizes the graphitization degree, and increases electrical conductivity, guaranteeing ensuring rapid electron and ion transfer. These coupling effects enable HC@PC−P anode to achieve a high reversible capacity of 350 mAh g−1 at 0.1 A g−1, an impressive initial coulombic efficiency of 89.6 %, and remarkable long-term cycling stability at 1 A g−1 over 1000 cycles with negligible capacity fade. The mechanisms behind sodium storage and enhanced electrochemical performance were elucidated by ex-situ Raman spectroscopy and kinetic analysis. Additionally, the assembled HC@PC−P//Na3V2(PO4)3 full cell demonstrated a high energy density of 257.9 Wh kg−1. This work provides a rational guide for designing advanced hard carbon anode materials for high-energy sodium-ion batteries.","PeriodicalId":132,"journal":{"name":"Batteries & Supercaps","volume":"8 6","pages":""},"PeriodicalIF":5.1,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144339144","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Silicon is among the most promising negative electrode materials due to its high theoretical capacity, abundant resources, and low working potential. However, its poor conductivity and significant volume expansion during cycling limit its practical application. To overcome these issues, this study develops a two-step synthesis method for a nanostructured composite based on silicon as the active material. First, a crumbled Ti3C2Tx (c-Ti3C2Tx) structure formed through electrostatic interaction between a Ti3C2Tx suspension and 1 M KOH. Then, an amorphous silicon layer is electrodeposited onto the c-Ti3C2Tx flakes in a room-temperature ionic liquid, creating the Si/c-Ti3C2Tx composite for the negative electrode of Li-ion batteries. The c-Ti3C2Tx structure enhances conductivity, provides mechanical stability to accommodate silicon's expansion, and offers nanostructured porosity for lithium-ion diffusion. The composite material demonstrates exceptional cycling stability, achieving a capacity of 1300 mAh g−1 at C/5 with 91 % capacity retention after 100 cycles.","PeriodicalId":132,"journal":{"name":"Batteries & Supercaps","volume":"8 5","pages":""},"PeriodicalIF":5.1,"publicationDate":"2024-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/batt.202400633","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144100633","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the sluggish oxygen redox kinetics impeded the efficiency and cycling performance during both the charge and discharge processes. To address this issue, we introduce a non-noble-trimetallic MnCo2-xCuxO4 (X=0 to 1) spinel interface as a bifunctional catalyst, to improve the reaction kinetics and cycle stability of LOBs. The half-filled eg orbital improves the synergistic interaction between Cu+/Cu2+, Co2+/Co3+, and Mn3+/Mn4+ redox pairs in the lattice, which enhances catalytic performance. In the series of MnCo2-xCuxO4 (X=0 to 1) spinel catalyst MnCo1.75Cu0.25O4 (MCU25) emerged as a standout performer. This exhibited notable half-cell performance, featuring superior ORR/OER bifunctional electrocatalytic activity with a ΔE of 1.15 V (vs RHE). Notably, the MCU25 cathode exhibited remarkable stability for over 1250 hours, enduring 225 cycles at 500 mA h g−1 and stable up to 70 cycles at a capacity limit of 1000 mA h g−1 in LOBs. Furthermore, it demonstrated an exceptional discharge-specific capacity of 11272 mA h g−1 at a current density of 175 mA g−1, exceeding the performance achieved by state-of-the-art RuO2 around 10180 mA h g−1.","PeriodicalId":132,"journal":{"name":"Batteries & Supercaps","volume":"8 6","pages":""},"PeriodicalIF":5.1,"publicationDate":"2024-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144339612","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

All electrodes in this work were prepared by an NMP-free, PFAS-free and scalable process. Full cells with areal capacities of 7 mAh/cm2 and 18 mAh/cm2 were assembled and tested. The results show an excellent cycling stability, reaching up to 950 cycles at 10 mA/cm2 for the cells with ultra-high-loading electrodes (capacity 18 mAh/cm2) and 650 cycles at 8 mA/cm2 for the cells with high-loading electrodes (capacity of 7 mAh/cm2). The influence of cathode porosity on the electrochemical performance in cells capacity of 7 mAh/cm2 showed that a lower porosity leads to a poorer rate capability as well as a worse cycling capability (400 cycles at 6 mA/cm2). Post-mortem analysis reveal that the anode aging is more pronounced during full cell cycling. Further the scalability of the production process was demonstrated by using a padder tool.

Temperature ramps and steps, ranging from 5 °C to 50 °C, are applied to capture the impact of entropic effects and aging mechanisms. Both methods effectively capture aging dynamics, showing strong agreement between ramp and step measurements. Deviations arise only in cases of strong entropy effects due to differences in measurement strategies. The findings confirm that float currents do not introduce additional aging beyond that captured by OCV measurements. The relationship between OCV and float current is governed by differential capacity <math></math>\u0000, which varies with cell voltage and temperature. Furthermore, strong deviations from classical differential voltage analysis but high agreement with local pulse measurements are observed, especially at low depths of discharge. This can be explained by the hysteresis effect of graphite.

The ionic conductivities of the 1 M LiBGB-TEP and 1 M LiBGB-TMP electrolytes are ca. 2–3 times lower than for the 1 M LiBGB-DMSO electrolytes (2.05, 2.65 vs. 5.70 mS cm−1 at 25 °C), and as compared to the state-of-the-art 1 M lithium hexafluorophosphate (LiPF6) in EC:DEC (EC:DEC=1 : 1 in vol., LP40) they display lower ionic conductivities, but the formers’ redox stability on aluminum (Al) and glassy carbon electrodes are much better. Concentrated (>1 M) LiBGB-DMSO electrolytes display enhanced redox stability, but worse Al passivation. Among the electrolytes, 1 M LiBGB-TMP achieves the best long-term stability over 300 h at 0.1 mA/cm2 for Li plating-stripping while the Li compatibility needs to be further improved.
