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.

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}

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}

By replacing the flammable and volatile electrolytes commonly found in traditional Li-ion batteries (LIBs) with noncombustible solid-state electrolytes (SSEs), we have the potential to fundamentally enhance safety measures. Concurrently, SSE would be capable of fitting high specific capacity (3860 mAh g−1) metal Li and is expected to break through the upper limit of mass-energy density (350 Wh kg−1) of existing LIBs system. Nevertheless, the growth of Li dendrites on the negative side or the nucleation of Li inside SSEs may give rise to battery short circuits, which is the primary factor limiting the application of Li metal. Recognizing this, the focus of this review is to provide a perspective for experimentalists and theorists who closely monitor various surface/interface and microstructure phenomena to understand Li dendrites. The strategies to reveal the complicated deposition mechanism and to control the dendrite growth of metal Li in solid-state batteries, as well as the advanced characterization methods of metal Li, provide suggestions for the practical research of solid-state Li metal batteries.","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/bte2.20230062","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139588590","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}

Focusing on BM, this article discusses the necessity of BM recovery and current recycling situations. Although the benefits of recycling are widely acknowledged, many challenges and issues remain. The BM market is still in its infancy and relevant regulatory frameworks need to be updated with respect to the widespread use and advancement of lithium-ion batteries. Current BM producing and processing technologies are gaining momentum and still have room for large improvements in terms of economic feasibility and environmental footprint.
