Being highly flammable, toxic, and volatile, leakage of such a liquid electrolyte is always considered a major safety risk. Hence, the improvement of liquid electrolytes remains an important goal, especially for high gravimetric energy battery systems like the lithium–sulfur battery (LSB), which is considered a suitable battery type to enable fully electric-powered aviation. Here, a study on the effects of a variation of the electrolyte media and salt was conducted to establish an inexpensive alternative liquid electrolyte system to the state-of-the-art DOL/DME electrolyte of LSB. The combination of DEGMEE and LiFSI led to the best cycling performance showing an increase in cycling stability (110 cycles at 97% Coulombic efficiency) and specific capacity (~500 mAh g−1 in the 110th cycle) at a moderately high C-rate of 0.25 C, which for our coin cell system translates to a moderate current of ~1.8 mA (~1.2 mA cm−2).","PeriodicalId":8807,"journal":{"name":"Battery Energy","volume":"3 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/bte2.20240002","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140561632","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 morphology of the active layer, which includes the phase separation structure, the degree of crystallinity of molecules, and the domain sizes, plays a critically important role in the performance, which is significantly influenced by the crystallization dynamics of the donor and acceptor. Therefore, it is crucial to comprehensively understand how the dynamics impact the film structure and how to effectively employ the kinetic procedure to enhance the structure of the active layer in OSCs. In this review, the methods and principles of kinetics characterization were introduced. Afterward, the latest advancements in the control of film-forming and the post annealing process are outlined, unveiling the underlying mechanism.

Among the various undoped hole transport materials (HTMs), D-π-A type polymers incorporating benzodithiophene (BDT) as the D unit and benzotriazole (BTA) as the A unit have shown promising potential. To further optimize the energy level and enhance the hole transport ability of these HTMs, we employed a fluorine substitution strategy to synthesize P-BTA-2F and P-BTA-4F based on the polymer P-BTA-0F. Subsequently, we investigated the impact of varying degrees of fluorine substitution on the properties of the polymer materials and the performance of the devices. As the number of F substitutions increases, the polymer energy level of the HTM gradually shifts downward, the face-on stacking of the HTM strengthens, the hole mobility of the HTM increases, and the rate of hole extraction and transport becomes faster. Ultimately, the CsPbI2Br PSCs based on the P-BTA-4F HTM achieve the highest power conversion efficiency (PCE) of 17.68%. Those findings demonstrate that selecting an appropriate amount of fluorine substitution is crucial for regulating the performance of polymer HTMs and improving device efficiency.","PeriodicalId":8807,"journal":{"name":"Battery Energy","volume":"3 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/bte2.20230065","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139945789","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}

Therefore, the development of an efficient approach to mitigate Si particle swelling and minimize interface parasitic reactions has emerged as a prominent research focus in both academia and industry. Here, a facile and scalable strategy is reported for the preparation of a double-layer coated submicron Si anode, comprising ceramic (silicon oxide) and graphene layers, denoted as Si@SiOx@G. In this approach, SiOx is in situ synthesized on the surface of Si and bonded with graphene through hydrogen bond interactions. The prepared Si electrode shows exceptional structural integration and demonstrates outstanding electrochemical stability, with a capacity retention of 92.58% after 540 cycles at 1 A g−1, as well as remarkable rate capability, achieving a specific capacity of 875 mAh g−1 at 2 A g−1.

Although all the cathodes exhibit a similar crystal structure as confirmed using X-ray diffraction and Raman spectroscopy, the contrasting difference is observed in their electrochemical properties. XRD and XPS analyses indicate a higher amount of cationic disorder for the NP cathodes compared to their NF counterparts. Nanofibrous Ni-rich layered oxide cathodes exhibit higher discharge capacities at all C-rates in comparison to NP cathodes. When cycled at 1C-rate for 100 cycles, capacity retention of 81% is observed for NCA-NF, which is superior to all cathodes. Voltage decay as a function of the charge–discharge cycle is found to be low (0.2 mV/cycle) for nanofibrous cathodes compared to 1.5 mV/cycle for NP cathodes. The good rate capability and cyclic stability of nanofibrous Ni-rich layered oxide cathodes are attributed to a shorter pathway of Li+ diffusion and a large proportion of the active surface area.","PeriodicalId":8807,"journal":{"name":"Battery Energy","volume":"3 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/bte2.20230066","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139588731","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}
