Enhancing the slope capacity of commercial HC is considered an optimal strategy for improving its rate performance. Bismuth metal is well-known for its exceptional rate capability and low-temperature performance. Herein, we report an effective approach for regulating the surface structure of commercial HC anodes by introducing bismuth nanoparticles and increasing oxygen functional groups. Particularly, polyvinylpyrrolidone self-assembled micelles were selected as the “core″ to facilitate the adsorption of Bi3+, which enables the nanocrystallization of the Bi-HC material to yield a carbon-coated Bi structure. Compared to commercial HC, the Bi-HC anode exhibits a significantly enhanced slope capacity (increase from 90 to 120 mAh g–1 at 0.1 A g–1) and rate capability (increase from 70 to 250 mAh g–1 at 2 A g–1) in the ether electrolyte. This surface regulation strategy offers a promising pathway for the development of high-performance HC anodes and the construction of efficient sodium-ion batteries.","PeriodicalId":4,"journal":{"name":"ACS Applied Energy Materials","volume":"8 7","pages":"4211–4219 4211–4219"},"PeriodicalIF":5.4,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143825362","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among them, tin-based flow batteries have attracted increasing interest in recent years due to their high solubility of active materials and the advantages of less dendrite formation. However, the stability and reaction mechanism of Sn-based ARFBs still need to be further investigated. This study presents the design and demonstration of an alkaline Sn–Fe ARFB with K4[Fe(CN)6] and K2Sn(OH)6 in the catholyte and anolyte respectively, achieving a high-capacity and low-cost electrochemical energy storage system. The active material K2Sn(OH)6 exhibits a solubility above 3 M in an alkaline electrolyte at a temperature of 60 °C, resulting in an anolyte volume capacity of 321.6 Ah L–1. It is determined using density functional theory computation that the binding energy between the surface of Sn and copper is higher than that of carbon-based materials, which leads to the formation of uniform small-particle crystal nuclei on the surface of the copper. Furthermore, the operando electrochemical tests prove that the solubility of SnO22– is still one of the reasons that the energy efficiency cannot increase steadily with increasing concentration. A capacity retention of 74% is achieved after 5000 cycles with a stable voltage >1.3 V for the Sn–Fe ARFB. The demonstrated high-capacity and low-cost alkaline Sn–Fe ARFB shows superior performance in cycle life by alleviating the dendrite issue compared with Zn-based ARFBs, providing a promising Sn-based anolyte for high-energy metal-based ARFBs.","PeriodicalId":4,"journal":{"name":"ACS Applied Energy Materials","volume":"8 7","pages":"4176–4183 4176–4183"},"PeriodicalIF":5.4,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143825209","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The deposition of SAMs on transparent conductive oxides (TCOs) provides uniformly thin layers that minimize charge transport losses, thereby simultaneously improving open-circuit voltage and fill factors in PSCs.

Nonetheless, the reduction of open-circuit voltage (VOC) at the interface within F-PSCs poses a significant barrier to improving the photoelectric conversion efficiency (PCE). Herein, we reported an effective “two birds with one stone” strategy by utilizing carbon dots (CDs) as a multifunctional treatment modulator to modify the SnO2 electron transport layer (ETL) and buried interface. On the one hand, CDs were explored to passivate trap states associated with Sn dangling bonds and oxygen vacancies on SnO2 surfaces through Lewis acid–base coordination, thereby enhancing the electron mobility of SnO2 films and facilitating charge extraction from perovskite layers. On the other hand, the functional groups (including carboxyl, fluorine, and amino) on CDs enable the formation of coordination and hydrogen bonding with PbI2, promoting the formation of high-quality perovskite films with reduced defect densities. The collective enhancements effectively mitigate trap-assisted charge recombination and interfacial energy loss, significantly reducing the device voltage deficit and enabling F-PSCs to attain a PCE of 22.97% with enhanced VOC from 1.06 to 1.18 V. Notably, CDs-incorporated devices demonstrate exceptional operational durability, maintaining 83% of initial PCE after 400 h of continuous illumination (AM 1.5G) in an air atmosphere and retaining 81% PCE following 4000 cyclic bending tests (6 mm radius).

However, LMO encounters rapid structural degradation at high current densities. To tackle this issue, we introduce K+ ions into the interstitial 16c sites to stabilize LMO, thereby achieving excellent fast-charging capability. The K-LMO retains 75% of its theoretical capacity at an ultrahigh current density of 1.48 A g–1 (10 C, corresponding to a charging time of 5 min). Comprehensive characterizations demonstrate that the incorporation of K+ into LMO expands the LiO4 space, strengthens the Mn–O bonds and suppresses the Jahn–Teller effect, leading to improved Li-ion mobility and enhanced stability of the diffusion channels. Additionally, the volume variation induced by cycling under a high charge state is efficiently suppressed through a solid-solution transition, thus preventing structural degradation against long-term cycling.

Herein, we investigate the interfacial reactions, thermoelectric and magnetocaloric properties of spark plasma sintered Bi0.4Sb1.6Te3–Cr5Te6 composites, where a spatially confined ferromagnetic Cr5Te6 phase is embedded into the Bi0.4Sb1.6Te3 thermoelectric matrix. The diffusion of Te element from Bi0.4Sb1.6Te3 into Cr5Te6 as a result of concentration gradient during sintering leads to the formation of interfacial phase Cr2Te3 and SbTe antisite defects in the Bi0.4Sb1.6Te3, both of which are detrimental to the thermoelectric and magnetocaloric performance of the composites. Sintering at a lower temperature effectively mitigates the interfacial reactions and suppresses SbTe antisite defects. Consequently, the room-temperature magnetocaloric and thermoelectric properties of the composites are concurrently optimized. Specifically, a high ZT value of 0.65 at 300 K and a relatively large magnetic entropy change ΔSmax = 0.33 J kg–1 K–1 at 5 T have been obtained for the Bi0.4Sb1.6Te3-15 wt % Cr5Te6 composite sintered at 625 K.
