Herein, we report a novel amorphous tin-titanium-ethylene glycol (Sn-Ti-EG) bimetal organic compound as anode for LIBs. The Sn-Ti-EG electrode exhibits exceptional cyclic stability with high Li-ion storage capacities. Even after 700 cycles at a current density of 1.0 A g-1, the anode maintains a capacity of 345 mAh g-1. The unique bimetal organic structure of the Sn-Ti-EG anode and the strong coordination interaction between Sn/Ti and O within the framework effectively suppress the aggregation of Sn atoms, eliminating the usual pulverization of bulk Sn through volume expansion. Further, the Sn M-edge of X-ray absorption near edge structure spectra obtained from the soft X-ray absorption spectroscopy signifies the conversion of Sn2+ ions to Sn0 during the initial lithiation process, which is reversible to Sn2+ upon de-lithiation. These findings manifest Sn being among the most active components that account for the excellent electrochemical performance of the Sn-Ti-EG electrode, while Ti has no practical contribution to the electrode’s capacity. The reversible formation of organic functional groups on the solid electrolyte interphase is also partly responsible for its cyclic stability.","PeriodicalId":124816,"journal":{"name":"Energy Materials and Devices","volume":"92 5-6","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135714162","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The active surface area remains almost invariable even after 15% macroscopic compressive strain. Furthermore, np-Pt shows a considerably high thermal stability due to the low surface diffusivity of Pt. The high surface-to-volume ratio and mechanical robustness makes np-Pt a promising surface- or interface-controlled functional materials in particular when not only excellent electrochemical performances but also good mechanical performance are demand. In this work, we demonstrated the potential application of np-Pt as an electrochemical actuation material. In-situ dilatometry experiments revealed the surface adsorption/desorption of OH species on np-Pt causes significant strain variations.

Nowadays, organic materials with sustainable and designable structures are of great interest as AZIB cathodes. However, small molecules in organic cathode materials face dissolution problems and suboptimal cycle life, while large molecules suffer from low theoretical capacity due to inert carbon skeletons. Here, we designed two covalent organic framework materials (BB-COF and TB-COF) with the same structure and number of energy storage groups to investigate the correlation between the densities of active sites and electrochemical performance. Our study concludes that the electrochemical behavior of organic conjugates-based energy storage materials doesn’t exhibit a linear correlation with active sites quantity. Adjusting active sites densities is crucial for material advancement. BB-COF and TB-COF, with dual active sites (C=O and C=N), exhibit distinct characteristics. TB-COF, with denser active groups, shows higher initial capacity (222 mAh g-1). Conversely, BB-COF, featuring a larger conjugated ring diameter, exhibits superior rate performance and enduring cycle stability. It even maintains stable cycling for 2,000 cycles at -40 ℃. More deeply, in-situ electrochemical quartz crystal microbalance (EQCM) reveals the energy storage mechanism of BB-COF storing H+ first and then Zn2+.","PeriodicalId":124816,"journal":{"name":"Energy Materials and Devices","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134915816","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
