In this work, a sulfinyl-functionalized imide anion, (trifluoromethanesulfinyl) (trifluoromethanesulfonyl)imide anion ([(CF<sub>3</sub>SO) (CF<sub>3</sub>SO<sub>2</sub>)N]<sup>−</sup>, [qTFSI]<sup>−</sup>), is proposed as negative charge for building low-melting ILs and high-performing electrolytes. The physicochemical properties of [qTFSI]-based ILs and their electrolytes are extensively characterized, and the reference systems with the classic sulfonimide anion, bis(trifluoromethanesulfonyl)imide anion ([(CF<sub>3</sub>SO<sub>2</sub>)<sub>2</sub>N]<sup>−</sup>, [TFSI]<sup>−</sup>) are also comparatively investigated. It has been revealed that the [qTFSI]<sup>−</sup> anion shows lesser extent of negative charge delocalization as compared to the reference [TFSI]<sup>−</sup> anion, which is responsible for slightly stronger interactions between IL cations and the sulfinyl-functionalized anion. The asymmetric feature of the [qTFSI]<sup>−</sup> anion contributes to lower glass and melting transitions of the corresponding ILs vs. [TFSI]-based ones, which effectively expands the operational temperature of the rechargeable batteries. Furthermore, the co-utilization of [qTFSI]<sup>−</sup> with [TFSI]<sup>−</sup> is found to improve the electrochemical compatibility of Li metal anode with the IL-based electrolytes, sustaining better cycling stability of the Li symmetric cells. The current work offers an elegant approach for the design of new anions for interface-favorable ILs and their electrolytes.</p></div>","PeriodicalId":34318,"journal":{"name":"Journal of Power Sources Advances","volume":"28 ","pages":"Article 100154"},"PeriodicalIF":5.4,"publicationDate":"2024-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666248524000209/pdfft?md5=7c9b6e2215ce8193cb108128d1d0697a&pid=1-s2.0-S2666248524000209-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141637166","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The TF methodology is validated through two application cases: ageing update and cell chemistry adaptation. Remarkably, using only 12 measurement points on the open-circuit voltage (OCV) envelopes instead of hundreds of measurement data points, the ageing update TF model attains a mean absolute error (mae) of 4.1 mV, closely approaching the accuracy of a newly parameterised target model (3.6 mV mae). Similarly, adapting an NCA cell model to an NMC target cell using selected OCV envelope points yields a 5.3 mV mae, which further reduces to 3.2 mV with an additional discharge FORB starting at 10% SOC. In addition to the selective model adjustment using continuous OCV measurement trajectories, the much more realistic adaptation by measurement points randomly distributed within the hysteresis window was successfully demonstrated.

Therefore, SoH prediction and monitoring for battery electric vehicles is necessary for extending LIB lifespan and avoiding failures. In this paper, an accurate real-time SoH prediction and monitoring method, based on discrete wavelet (DWT) analysis, is investigated through an extensive experimental campaign considering the effect of temperature variation. Specifically, moving from cycle aging performed on Li-ion NCR 18650 cells and applying two typical US test drive cycles at different SoHs, three different operating temperatures (i.e., 0 °C, 20 °C and 30 °C) were investigated. Applying DWT on the gathered LIB voltage profiles, it is demonstrated that temperature effect on the implemented method is easily recognizable from the one of cycle aging. Moreover, suitable linearized functions are identified to refer DWT outcomes assessed at the operative temperature to a reference temperature, at which a suitable equation is previously identified to assess capacity fading.

Our study reveals that Na thin anodes &lt;10 μm, directly coated on a stainless-steel current collector, reduces the energy barrier of Na nucleation during plating process. Likewise, evaporated thin-film sodium anodes enable achieving a cycling in a full battery configuration as stable as with bulk Na anode, and considerably more stable than the here presented anode-less case. These insights may lead to practical design changes toward the efficient use of metallic Na, alleviating weight and costs. In addition, they provide a solid starting point for future developments that focus on improving the stability and extending the life of Na-metal batteries. All this paves the way for the next-generation of sodium-based energy storage technologies, where energy density and cost are key factors.</p></div>","PeriodicalId":34318,"journal":{"name":"Journal of Power Sources Advances","volume":"26 ","pages":"Article 100137"},"PeriodicalIF":4.5,"publicationDate":"2024-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666248524000039/pdfft?md5=bb33af74c02369e3691fedab93ae37eb&pid=1-s2.0-S2666248524000039-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139503900","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
