However, they suffer from fast capacity decay and low Coulombic efficiency in carbonate electrolytes because the organic solid electrolyte interphase (SEI) strongly bonds to the alloys, leading to cracks of both SEI and alloying particles, which allows electrolyte penetration and forms new SEI during lithiation–delithiation cycles. Using nano-sized alloying anodes can enhance the cell cycle life but also reduces the battery calendar life and increases the manufacturing costs. Here we significantly improved the cycle performance of micro-sized Si, Al, Sn and Bi anodes by developing asymmetric electrolytes (solvent-free ionic liquids and molecular solvent) to form LiF-rich inorganic SEI, enabling 90 mAh μSi||LiNi0.8Mn0.1Co0.1O2 and 70 mAh Li3.75Si||SPAN pouch cells (areal capacity of 4.5 mAh cm−2; N/P of 1.4) to achieve >400 cycles with a high capacity retention of >85%. The asymmetric electrolyte design forms LiF-rich interphases that enable high-capacity anodes and high-energy cathodes to achieve a long cycle life and provide a general solution for high-energy Li-ion batteries.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":null,"pages":null},"PeriodicalIF":56.7,"publicationDate":"2024-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142007635","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here we find that mixed Sn–Pb perovskite thin films exhibit a compositional gradient, with an excess of Sn on the surface—and we show this gradient exacerbates oxidation and increases the recombination rate. We find that diamines preferentially chelate Sn atoms, removing them from the film surface and achieving a more balanced Sn:Pb stoichiometry, making the surface of the film resistive to the oxidation of Sn. The process forms an electrically resistive low-dimensional barrier layer, passivating defects and reducing interface recombination. Further improving the homogeneity of the barrier layer using 1,2-diaminopropane results in more uniform distribution and passivation. Tandems achieve a power conversion efficiency of 28.8%. Encapsulated tandems retain 90% of initial efficiency following 1,000 h of operating at the maximum power point under simulated one-sun illumination in air without cooling.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":null,"pages":null},"PeriodicalIF":56.7,"publicationDate":"2024-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141986477","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Unfortunately, the QD solar cell is hampered by the time-consuming layer-by-layer process, a major challenge in manufacturing printable devices. Here we demonstrate a sequential acylation-coordination protocol including amine-assisted ligand removal and Lewis base-coordinated surface restoration to synthesize conductive APbI3 (A = formamidinium (FA), Cs or methylammonium) colloidal perovskite QD (PeQD) inks that enable one-step PeQD film deposition without additional solid-state ligand exchange. The resultant PeQD film displays uniform morphology with elevated electronic coupling, more ordered structure and homogeneous energy landscape. Narrow-bandgap FAPbI3 PeQD-based solar cells achieve a champion efficiency of 16.61% (certified 16.20%), exceeding the values obtained with other QD inks and layer-by-layer processes. The conductive PeQD inks are compatible with large-area device (9 × 9 cm2) fabrication using the blade-coating technique with a speed up to 50 mm s−1.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":null,"pages":null},"PeriodicalIF":56.7,"publicationDate":"2024-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141974115","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here we gathered year-long records from 61,598 electric trucks in China. Current electric trucks were found to be significantly underutilized compared with their diesel counterparts. Twenty-three per cent of electric delivery trucks and 30% of semi-trailers could achieve one-on-one replacement with diesel counterparts, while on average 3.8 electric delivery trucks and 3.6 electric semi-trailers are required to match the transportation demand that is served by one diesel truck separately. For diesel trucks that are capable of one-on-one replacement, electric trucks have 15–54% and 1–49% reductions in cost and life-cycle CO2 emissions, respectively. Enhancements in usage patterns, vehicle technologies and charging infrastructure can improve electrification feasibility, yielding cost and decarbonization benefits. Increased battery energy densities with optimized usage can make one-on-one electrification feasible for more than 85% of diesel semi-trailers. In addition, with cleaner electricity, most Chinese electric trucks in 2030 will have lower expected life-cycle CO2 emissions than diesel trucks.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":null,"pages":null},"PeriodicalIF":56.7,"publicationDate":"2024-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141918866","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Previous research has emphasized the role of iodide and silver oxidation, and the role of hole tunnelling from the electron-transport layer into the perovskite to enable the flow of current under reverse bias in causing degradation. Here we show that device architecture engineering has a significant impact on the reverse bias behaviour of perovskite solar cells. By implementing both a ~35-nm-thick conjugated polymer hole transport layer and a more electrochemically stable back electrode, we demonstrate average breakdown voltages exceeding −15 V, comparable to those of silicon cells. Our strategy for increasing the breakdown voltage reduces the number of bypass diodes needed to protect a solar module that is partially shaded, which has been proven to be an effective strategy for silicon solar panels. Perovskite solar cells degrade when subjected to reverse bias. Jiang et al. show that relatively thick hole transport layers and metal back contacts with improved electrochemical stability afford better tolerance to reverse bias.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":null,"pages":null},"PeriodicalIF":49.7,"publicationDate":"2024-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141899746","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
