Introducing an initially dual-electrode-free (anode/cathode) configuration can further boost energy density to over 200 Wh kg−1, but with limited cycle life due to the poor reversibility of Zn/MnO2 deposition and stripping. Drawing inspiration from soft templating strategies in material synthesis, here we apply this approach to electrodeposition and stripping by designing an in situ formed liquid crystal interphase. This concept is achieved by incorporating just 0.1 mM of surfactant molecules into the electrolyte, which induces favourable c-axis orientations in depositing both hexagonal Zn and MnO2. This enhancement subsequently increases the deposition/stripping reversibility and promotes the cycle life of the dual-electrode-free battery, achieving 80% capacity retention after ~950 cycles. This liquid crystal interphase chemistry also holds great promise for regulating deposition in other crystal systems, opening an exciting research direction for next-generation high-energy-density and long-duration energy storage based on aqueous chemistries. Achieving long-cycle-life, aqueous, dual-electrode-free Zn/MnO2 batteries with high energy density is challenging. This work introduces a liquid crystal interphase in the electrolytes with soft templating effects, considerably enhancing performance.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":"9 11","pages":"1350-1359"},"PeriodicalIF":49.7,"publicationDate":"2024-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142275968","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}

This study quantifies the extent of this variability by providing commercially sourced battery materials—LiNi0.6Mn0.2Co0.2O2 for the positive electrode, Li6PS5Cl as the solid electrolyte and indium for the negative electrode—to 21 research groups. Each group was asked to use their own cell assembly protocol but follow a specific electrochemical protocol. The results show large variability in assembly and electrochemical performance, including differences in processing pressures, pressing durations and In-to-Li ratios. Despite this, an initial open circuit voltage of 2.5 and 2.7 V vs Li+/Li is a good predictor of successful cycling for cells using these electroactive materials. We suggest a set of parameters for reporting all-solid-state battery cycling results and advocate for reporting data in triplicate. More transparent protocol reporting and comprehensive battery cell data are needed. Twenty-one research groups joined forces to assess solid-state battery performance and found considerable differences in assembly protocols that cause variable results.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":"9 10","pages":"1310-1320"},"PeriodicalIF":49.7,"publicationDate":"2024-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s41560-024-01634-3.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142236847","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, standardized methods for quantifying capacity fade during field operation are lacking, and therefore the European batteries regulation demands the development of reliable and transparent state of health estimations. Here we present real-world data from 21 privately operated lithium-ion systems in Germany, based on up to 8 years of high-resolution field measurements. We develop a scalable capacity estimation method based on the operational data and validate it through regular field capacity tests. The results show that systems lose about two to three percentage points of usable capacity per year on average. Our contribution includes the publication of an impactful dataset comprising approximately 106 system years, 14 billion data points and 146 gigabytes, aiming to address the shortage of public datasets in this field. In battery research, the demand for public datasets to ensure transparent analyses of battery health is growing.

However, the effect is influenced by the targeted substrate and, in particular, by its bond with the interfacial molecule. A weaker bonding of the interfacial molecule with the substrate usually implies a stronger bonding with the perovskite that could lead to uncontrollable insertion of the interfacial molecule into the perovskite bulk, resulting in device degradation. Here we select bis(2-aminoethyl) ether (BAE) as the interfacial molecule between the perovskite and the electron transport layer (ETL) in n–i–p PSCs and develop a strategy to harmonize the strength of the bilateral bonds of BAE. In particular, we manipulate the electronic structure of the ETL with doping to increase the strength of the BAE–ETL bond. This thereby results in a weakening of the BAE–perovskite bond. The harmonization in bilateral bonds of the interfacial molecule leads to PSCs with an efficiency surpassing 26.5% (certified as 26.31%) and improved stability. The interfaces in perovskite solar cells are critical to the device performance. Li et al. tune the bond strength of the interfacial molecule with the perovskite and the electron transport layer, increasing the power conversion efficiency of the cells.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":"9 12","pages":"1506-1516"},"PeriodicalIF":49.7,"publicationDate":"2024-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142234492","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}

Its industrial scalability requires electrocatalysts to be highly selective to certain products, such as ethylene or ethanol. However, a substantial knowledge gap prevents the design of tailor-made materials, as the properties ruling the catalyst selectivity remain elusive. Here we combined in situ surface-enhanced Raman spectroscopy and density functional theory on Cu electrocatalysts to unveil the reaction scheme for CO2RR to C2+ products. Ethylene generation occurs when *OC–CO(H) dimers form via CO coupling on undercoordinated Cu sites. The ethanol route opens up only in the presence of highly compressed and distorted Cu domains with deep s-band states via the crucial intermediate *OCHCH2. By identifying and tracking the critical intermediates and specific active sites, our work provides guidelines to selectively decouple ethylene and ethanol production on rationally designed catalysts. Electrochemical reduction of CO2 can yield many different products; a better understanding of the key mechanisms at play is needed to guide the design of selective catalysts. Here the authors use in situ surface-enhanced Raman spectroscopy and simulations to elucidate reaction schemes for CO2 reduction to ethylene and ethanol.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":"9 12","pages":"1485-1496"},"PeriodicalIF":49.7,"publicationDate":"2024-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s41560-024-01633-4.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142166500","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
