Among them, coupling lithium metal (Li) with nickel-rich LiNixMnyCozO2 (NMCs, x ≥ 0.6, x + y + z = 1) is promising, for Li anodes enable an extremely high capacity (3860 mAh g−1) and the lowest redox potential (−3.04 V vs. standard hydrogen electrode) while NMCs can achieve a much higher capacity of 200 mAh g-1 and lower cost than those of LiCoO2. However, the resultant Li||NMC cells have been hindered from commercialization, due to a series of challenges related to the interface stability of both Li anodes and NMC cathodes. Specifically, Li anodes suffer from Li dendritic growth and the formation of solid electrolyte interphase (SEI), while NMC cathodes have been harassed by the formation of cathode electrolyte interphase (CEI), and other interface-related issues including transition metal dissolution, oxygen release, cracking, and so on. To tackle these issues, recently, two sister techniques, atomic and molecular layer deposition (ALD and MLD), have emerged and exhibited tremendous capabilities to accurately constitute robust interfaces for accomplishing high-performance Li||NMC LMBs. They can uniquely develop uniform and conformal films as surface coatings of LMBs in a precisely controllable mode at the atomic/molecular level while proceeding film deposition at low temperatures (e.g., ≤ 250 oC). In this Feature Article, we highlight our latest research progress in developing novel surface coatings via ALD and MLD for Li||NMC LMBs and discuss our outcomes in pursuing their high performance.","PeriodicalId":67,"journal":{"name":"Chemical Communications","volume":"5 1","pages":""},"PeriodicalIF":4.9,"publicationDate":"2024-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142815509","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The reaction proceeds through the concerted metalation-deprotonation (CMD) mechanism by activation of vinyl C-H bond with imidoylpalladium assisted by the carboxylate. Quinoline as an important heterocyclic scaffold, is prevalently found in natural products, biologically active molecules and functional materials,1 and is also a useful synthon in organic synthesis.2 Thus, various synthetic methods for quinoline motifs have been developed. Representative approaches include condensation reactions3 and catalyzed addition/cyclization approaches.4 Despite these advances, there remains big demand for versatile and eﬀective methodologies to regioselective construct multiple substituted quinoline motifs. Aryl isocyanides have been well exploited in the preparation of nitrogen-containing heterocycles.5 In this context, alkene-containing isocyanides have received much attention, because they can be easily tuned in a way to synthesize a plethora of N-heterocyclic derivatives.6 Takahashi et al reported a three-component coupling reaction of o-alkenylphenyl isocyanides with aryl iodides and amines in the presence of palladium catalyst to produce 2,3-substituted indoles (Figure 1).6a Zhu group reported synthesis of ﬁve- to seven-membered cyclic ketoimines through palladium-catalyzed intramolecular imidoylative Heck reaction of alkene-containing isocyanides.6b Wang et al reported the palladium-catalyzed reaction of alkene-containing isocyanides with N-(2-bromobenzoyl)indoles via","PeriodicalId":67,"journal":{"name":"Chemical Communications","volume":"28 1","pages":""},"PeriodicalIF":4.9,"publicationDate":"2024-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142815512","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Generally, the phase growth procedures of NaxTMO2 during solid-state reactions at high temperature closely related to their carbon footprint, prime cost, and the eventual electrochemical properties, while the thermal stability in various desodiated states associated with wide temperature fluctuations are extremely prominent to the electrochemical properties and safety of SIB devices. Therefore, in this review, the influences of sintering conditions such as pyrolyzation temperature, soaking time, and cooling rate on the phase growth patterns of NaxTMO2 are summarized. The thermodynamic and kinetics competitive driving behaviors at the highest temperature for the phase growths are deeply discussed. Furthermore, for the thermal stability of NaxTMO2 cathodes, the phase transition behaviors along with the alterations of battery system temperature under various electro-/chemical environments are concluded. The thermal stability enhancement strategies such as elemental composition modulations, surface reconstructions, and polyphase symbiosis using in the previous works are overviewed. Finally, we prospect the high-efficient preparation methods and the thermal devastation regulations of the NaxTMO2 layered oxides.","PeriodicalId":67,"journal":{"name":"Chemical Communications","volume":"50 1","pages":""},"PeriodicalIF":4.9,"publicationDate":"2024-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142815505","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
