Historically, improved sustainability comes with a penalty in terms of cost and performance. This interplay will certainly evolve in the coming years. Ecological and social aspects driven by legislative frameworks guarantee recycling of lithium-ion batteries (LIBs) to prevent hazardous waste in landfills. The trend in the electric vehicle (EV) sector towards low-cost chemistries like lithium iron phosphate (LFP) represents a double-edged sword, as the recycling profitability of such materials is extremely low for the established recycling methods. Extending battery lifetime and enabling direct recycling, where anode and cathode materials maintain their structure and functionality, are key strategies to increase sustainability and profitability. However, their implementation necessitates a shift in LIB design priorities. This Perspective highlights design for circularity as an enabler for improved battery longevity and direct recycling and represents a key tipping element for reducing cost and increasing sustainability in LIB production and disposition concurrently. We outline challenges and opportunities in battery production with special focus on the European EV sector and define actions required from various stakeholders along the value chain to overcome the mindset of linear economies.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":" 22","pages":" 8529-8544"},"PeriodicalIF":32.4,"publicationDate":"2024-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2024/ee/d4ee03418j?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142431658","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}

Here we investigate a broad range of Y-type acceptors using a combination of experimental and theoretical studies. We first show that a transient electroabsorption (TEA) signal is universal in neat Y-type acceptor films upon photoexcitation, which is caused by the formation of intermolecular charge-transfer (ICT) states in tightly packed molecular aggregates (i.e. ordered regions of the film). Tracking the TEA signal growth dynamics can monitor the migration of excitons from disordered to ordered regions in various Y-type acceptor films on the sub-picosecond timescale. Importantly, our results reveal that Y-type acceptors with moderately reduced intermolecular interaction strength can generally achieve faster exciton migration, better structural uniformity and higher device performance, thereby providing insights for future OPV material development and engineering.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":" 22","pages":" 8776-8786"},"PeriodicalIF":32.4,"publicationDate":"2024-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142431188","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}

The Co3O4−xFx catalyst exhibits a relatively low overpotential of 349 mV at 10 mA cm−2 and operation durability of 120 h at 100 mA cm−2 for the acidic OER, making it one of the best-performing non-noble metal catalysts.

However, the low frequency and chaotic nature make it difficult for TENGs to generate stable electrical outputs, posing challenges for directly powering electronics and designing universal power management circuits. Inspired by the consistent and steady energy output of octave boxes, we propose a novel energy regularization triboelectric nanogenerator (ER-TENG). Chaotic wave energy is temporarily stored in coil springs by one-way bearings and then converted into a controlled rotation to drive TENGs through the synergistic effect of a gear set and a centrifugal speed limiter. The relationship between the rotational speed and the configuration of the gear set/centrifugal speed limiter is investigated to optimize the mechanical transmission efficiency. Moreover, the utilization of ternary dielectric materials and multi-layer stacked units enhances the electro-mechanical conversion efficiency, resulting in an average power density of up to 15.67 W m−3. Fast charging of capacitors is achieved through the ER-TENG using a simple power management circuit. In practical applications, the ER-TENG demonstrates the capability to continuously power offshore appliances. This energy regularization strategy enables TENGs to directly output a stable signal, which serves as a significant reference for the development of smart ocean systems.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":" 22","pages":" 8829-8837"},"PeriodicalIF":32.4,"publicationDate":"2024-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142404990","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}

Alkaline zincate (ZHS) forms with the H+/Zn2+ co-intercalation, which partially covers the cathode surface at small mass loading while fully covers the cathode surface under large mass loading. DIMS involves regulating MnO2 by interstitial carbon (IC@MnO2) to suppress the affinity toward OH−/SO42−, thus impeding ZHS coverage. We develop an accurate method to quantify the zinc storage amount normalized by manganese, which shows that IC@MnO2 exhibits zinc storage enhancement by 182.4% compared to bare MnO2.

Nevertheless, the influence of lattice vacancies on electrochemical performance has not been thoroughly clarified, hindering the further development of PBAs. Here we identify two types of functional vacancies, namely structural vacancy (SV) and incidental vacancy (IV) in manganese hexacyanoferrate (MnHCF) through Synchrotron-based X-ray absorption spectroscopy and density functional theory calculations. Unlike structurally disordered IV, the introduction of structurally ordered SV promotes ion transport and reduces the interaction between host ions and the framework, enabling improved cyclic and rate performance. The controllable adjustment of SV in K-rich MnHCF is achieved through a co-reactant method. Furthermore, the partial introduction of SV in K-rich MnHCF is demonstrated to favor both a milder structural evolution by alleviating the Jahn-teller distortion of Mn3+ and a stable dynamic process of interface reaction. This study unveils the potential importance of incorporating structural vacancy into MnHCF for advanced energy storage applications.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":"1 1","pages":""},"PeriodicalIF":32.5,"publicationDate":"2024-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142397834","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}

In this perspective, we argue that catalysing SAF production from the very low level of 2022 (0.1% of the 2050 required level for net-zero) can be achieved via the establishment of “green flight paths” (GFPs) that kick-start SAF implementation through targeted support from key international partner countries. The development of GFPs builds on the Clydebank Declaration from COP26 for green shipping corridors, which is aimed at transforming emissions at sea. Similarly, we define here GFPs as specific aviation routes where financially viable supply chain opportunities for zero-emission air-travel are incentivised. We examine here how GFPs are likely to be spearheaded by countries, such as the UK and the UAE, which are both large international aviation markets that have the political, technical and production capabilities to be world-leaders in pursuing the earlier stages of investment (which are inherently riskier) in developing SAF commercial production capacity for the decarbonization of their aviation sectors. We further discuss how from an energy justice perspective, GFPs are ideal for catalysing SAF adoption and cost reduction in a just way by placing the burden where accountability is required.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":"9 1","pages":""},"PeriodicalIF":32.5,"publicationDate":"2024-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142397833","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}

We show that, upon improved colloidal dispersibility and surface passivation, AgBiS2 NCs yield thin films free from morphological defects with low trap-state density and balanced charge carrier mobilities.

Recently, covalent organic frameworks (COFs) have been emerged as suitable support platforms to anchor single-atom catalysts (SACs) and dual-atom catalysts (DACs), owing to their high porosity, pre-design capability, and tunable structures. In this review, we first classified the types of SA/DA sites in COFs based on the numbers and coordination structures of catalytic centers. Microenvironment engineering mainly involving metal center-ligands in the first coordination shell, the symmetry of coordinating atoms, local electronic structure modulation and the site distance effect was unravelled for COF based single/dual-atom active sites. Then, we systematically summarized the design principles, synthetic strategies and advanced characterization techniques of state-of-the-art COF-based SACs/DACs. Furthermore, COF-based SACs/DACs for applications in energy conversion (electrocatalysis and photocatalysis) and storage (lithium, sodium and potassium-ion batteries) were comprehensively highlighted and discussed in-depth, focusing on revealing the relationship of structure–performance.
