In this work, we examine the role of a cathode composite microstructure composed of solid-state electrolyte (SSE) with different particle sizes. A composite made of LiNi0.8Co0.1Mn0.1O2 (NCM811) and fine-particle Li6PS5Cl (LPSC) shows a more uniform distribution of SSE on the surface of NCM811 particles, ensuring intimate contact. Moreover, the composite features reduced tortuosity, which enhances Li ion conduction. These microstructural advantages result in significantly reduced charge transfer resistance, helping to suppress mechanical distortion and electrochemical degradation during cycling under low-pressure conditions. As a result, the fine-LPSC cathode composite exhibits enhanced cycling stability at a moderate stack pressure of 2 MPa, outperforming its coarse-LPSC counterpart. Our finding confirms the important role of microstructure design in enabling high-performance ASSBs operating under low-pressure conditions.","PeriodicalId":16,"journal":{"name":"ACS Energy Letters ","volume":"10 2","pages":"966–974 966–974"},"PeriodicalIF":19.3,"publicationDate":"2025-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143402214","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}

Effective recycling methods are crucial to mitigating material scarcity, enhancing sustainability, and fostering a circular economy. This perspective examines the current LIB recycling processes, with a focus on the emerging potential and challenges of direct recycling methods. Unlike traditional pyrometallurgy and hydrometallurgy, which often destroy valuable materials, direct recycling seeks to recover and restore functional components, preserving the integrity of active materials. However, this method faces significant technical hurdles, particularly due to the complex design of LIBs and the degradation of key components over time. This perspective explores the intricacies of battery structure and component degradation, examines the challenges of scaling up direct recycling for industry applications, and proposes future directions to improve the efficiency and viability of this sustainable recycling approach.","PeriodicalId":16,"journal":{"name":"ACS Energy Letters ","volume":"10 2","pages":"947–957 947–957"},"PeriodicalIF":19.3,"publicationDate":"2025-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143402212","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 article aims to explain how the introduction of the Q-PHJ architecture can mitigate degradation under various conditions without compromising device performance. It begins by illustrating the fundamental mechanisms responsible for the degradation of OPV devices. Following this, the advantages of the Q-PHJ device and the mechanism are explained by introducing our recent work as well as highlighting other researchers’ work in this field. Different aspects and factors such as morphology, the ternary strategy, additive engineering, and vertical distribution were analyzed. The role of material innovation is also discussed.

The application of thermoelectric technology is closely related to materials’ thermoelectric and mechanical properties. However, the strong coupling of key parameters involving charge carriers and phonon transport hinders the substantial improvements in overall thermoelectric performance. In recent years, a high-entropy strategy promoted remarkable progress in the field of thermoelectric materials by leveraging the four core effects. In this review, we first discuss the theoretical basis for how a high-entropy strategy synergistically optimizes thermoelectric performance. We then classify the examples where high-entropy effects can optimize electrical, thermal, and mechanical properties in thermoelectric materials. Following this, we summarize the overall advances that the high-entropy strategy has brought to thermoelectric materials and devices. Finally, we point out the remaining challenges in high-entropy thermoelectrics and offer perspectives on future research directions in this field.","PeriodicalId":16,"journal":{"name":"ACS Energy Letters ","volume":"10 2","pages":"925–934 925–934"},"PeriodicalIF":19.3,"publicationDate":"2025-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143402198","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}
