The emerging solid polymer electrolytes (SPEs) have been extensively applied to construct solid-state lithium batteries, which hold great promise to circumvent these problems due to their merits including intrinsically high safety, good stability, and high capacity of lithium (Li) metal. Single-ion conducting polymer electrolytes (SICPEs) have great advantages over traditional SPEs due to their high lithium transference numbers (LTN) (near to 1). SICPEs improve the overall performance of the battery by suppressing both concentration polarization and impedance. Herein, this review is to offer timely update of the development of SPEs for solid-state lithium battery applications. Generally, the fundamental principles, classification, key parameters, and ion transport mechanisms of SPEs are summarized, followed by a discussion on the modification method. Furthermore, for SICPEs, a special focus is on synthesis and tuning of negative charge dispersion. In addition, artificial intelligence (AI) and machine learning (ML) in material design for SPEs are pointed out. Moreover, we bring up the challenges and offer solutions for further development of SPEs in solid-state lithium batteries.","PeriodicalId":18277,"journal":{"name":"Materials Today Energy","volume":"40 1","pages":""},"PeriodicalIF":9.3,"publicationDate":"2024-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140837890","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, NVP system is modified by introducing sodium carboxymethyl cellulose (Na CMC) to achieve triple modification effects: sodium-rich, cross-linked carbon coating network, and carbon layer surface modification. Meanwhile, CMC, as a porous carbon substrate with large pores, provides a fast migration channel for Na. Similarly, carbon nanotubes (CNTs) grown from the active particles become the connecting carriers between the active particles, thus effectively improving the electron transport. Notably, the scanning electron microscopy (SEM) and transmission electron microscopy (TEM) images after cycling verify the stabilized porous structure of the NaV(PO)/C@0.7wt.%CMC@CNTs (0.7wt.%CMC@CNTs) composite. Distinctively, the modified 0.7wt.%CMC@CNTs reveals a capacity of 111.4 mAh/g at 0.1 C. It submits a high value of 105.0 mAh/g at 1 C with a capacity retention rate of 84.10% after 1,000 cycles. Even at 15 C, it still releases 86.6 mAh/g with a low capacity decay rate of 0.0230% per cycle after 3,600 cycles.

It has shown great potential in industrial applications due to the overwhelming advantages of high device efficiency and low cost. Here, we introduce a novel crystallization method using ultrafast laser-annealing by scanning a laser spot onto the surface of hydrogenated amorphous silicon film in TOPCon solar cells. By circumventing the high-temperature environment of the conventional annealing process, it can prevent a large number of dopant atoms from penetrating inside the crystalline silicon (c-Si) substrate, reducing the Auger recombination. Moreover, we can conduct extensive experiments to clarify the optimal conditions, including laser-annealing modes and process parameters. The hydrogenation experiments reveal that direct appropriation of the traditional hydrogenation method is not applicable. An additional ‘dehydrogenation’ step proves necessary, indicating that the differences in hydrogen content within the films due to the divergence between the principles of laser-annealing and high-temperature annealing are probably responsible for this. Consequently, the proof-of-concept devices using laser-annealing technology realize a champion efficiency of 19.91%,highlighting an alternative technical route with substantial potential to achieve high-efficiency crystalline silicon solar cells.","PeriodicalId":18277,"journal":{"name":"Materials Today Energy","volume":"13 1","pages":""},"PeriodicalIF":9.3,"publicationDate":"2024-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140591706","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Considering the Li deposition is a dynamic electrochemical process, the external filed regulation has become a hotspot strategy to promote the cycling performance and safety application of Li mental anodes (LMA). Herein, we focus on the external fields involved during Li deposition, systematically summarizing the current progress of external field regulation for LMA. The mechanisms and limitations in regulating Li deposition are amply discussed. New perspectives and future research directions are also provided.

Compared with the popular ammonium-based perovskites, density-functional theory computation suggests that MPSnBr possesses a wider bandgap and lower conduction band minimum (CBM) level induced by the weak-hybrid MP cations, which can be a more suitable wide-range light absorber than its traditional ammonium counterparts. We show that such a heterostructure exhibits a desirable positive ”spike-like” BO, resulting in higher V and more effective suppression of undesirable carrier recombination. Hence, MPSnBr as a structural well-matched absorber, can potentially serve as the wide-range subcell in perovskite tandem cell devices.","PeriodicalId":18277,"journal":{"name":"Materials Today Energy","volume":"69 1","pages":""},"PeriodicalIF":9.3,"publicationDate":"2024-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140201339","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As an electron feeder, these resonance states significantly improve transport properties within the Al–BiSe semiconductors. The theoretical calculation shows the creation of the resonance states by hybridizing the dopant’s -orbitals with the host’s -orbitals near the Fermi level. The Al–BiSe semiconductors effectively moderate electron concentration and Seebeck-dependent effective mass, resulting in an ultrahigh zT of 0.57 over a broad temperature range of 300–473 K. The nanoparticle size (∼20 nm) efficiently impedes the propagation of lattice vibration, leading to an ultralow total thermal conductivity of 0.399 WmK.

Herein, we aim to address another important interface, namely, the indium tin oxide/electron transport layer (ITO/ETL) interface in n-i-p structured devices. Since electron transport layers are typically fabricated using commercial nano tin dioxide, which often display insufficient density. To combat this, we employ the most commonly used bathocuproine (BCP) material to treat the ITO/ETL interface. The incorporation of BCP diminishes the direct contact between the perovskite and ITO layers, while also passivating buried interface and adjusting the crystal orientation of perovskites. Furthermore, the substrate layer exhibits improved transparency, consequently elevating the utilization rate of light by perovskite. As a result, the BCP-based PSC exhibits an impressive efficiency greater than 22%, surpassing the control one of 19.91%, and which simultaneously demonstrates excellent stability. Notably, the optimization of this interface has universal applicability in the improvement of PSCs performance.","PeriodicalId":18277,"journal":{"name":"Materials Today Energy","volume":"136 1","pages":""},"PeriodicalIF":9.3,"publicationDate":"2024-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140127743","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a result, after 3 minutes of UVO treatment, an enhanced recoverable energy density of 4.79 J/cm with a charge-discharge efficiency of >95% is obtained under 650 MV/m at room temperature (RT). Significantly, stable energy storage performance under 200 MV/m maintains throughout a broad temperature range from -90°C to 90°C and during 20000 cycles of charge-discharge procedures. According to first-principles calculations and thermally stimulated depolarization current measurements, formation of carbonyl groups (C=O) after UVO treatment could effectively passivate initial deep-level defect states caused by H vacancies, which explains the improvement in capacitive energy storage. Moreover, the metalized UVO-modified PE exhibits valuable breakdown self-clearing ability, and the self-cleared specimen maintains stable energy storage performance over 20000 cycles at 200 MV/m and RT.
