High pyroelectric coefficients are the focus of optimizing pyroelectrics. Elevated pyroelectric coefficients not only contribute to the efficiency of energy conversion and signal resolution to be enhanced but also facilitate device miniaturization and cost reduction. However, the pyroelectric coefficients are typically below 1,000 μC/m²K. Here, we achieve a 14-fold enhancement in the pyroelectric coefficient of 8,194 μC/m²K at room temperature for lead magnesium niobate-lead titanate (PMNT) single crystals. This enhancement can be attributed to a synergistic strategy of doping and interface engineering, which enables the coupling of both intrinsic and interface pyroelectricity. Moreover, doping and interface engineering, respectively, contribute to intrinsic pyroelectricity by altering domain structure and polarization and through interface pyroelectricity by introducing polar symmetry. This synergistic strategy provides a framework to design high-performance pyroelectrics for applications in thermal batteries, infrared sensors, and medical imaging devices.</div></div>","PeriodicalId":343,"journal":{"name":"Joule","volume":"8 12","pages":"Pages 3426-3435"},"PeriodicalIF":38.6,"publicationDate":"2024-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142439780","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 highlight their strengths and weaknesses amidst the challenges of a changing grid. It is argued that FMs learning from diverse grid data and topologies, which we call grid foundation models (GridFMs), could unlock transformative capabilities, pioneering a new approach to leveraging AI to redefine how we manage complexity and uncertainty in the electric grid.

We identify two key parameters, formation charge current and temperature, that control battery longevity via distinct mechanisms. Surprisingly, high-formation charge current on the first cycle extends battery cycle life by an average of 50%. Unlike elevated formation temperature, which boosts battery performance by forming a robust SEI, the cycle life improvement for fast-formed cells arises from a shifted electrode-specific utilization after formation. Apart from the widely acknowledged role of formation in governing SEI properties, we demonstrate how formation protocols determine the stoichiometry range over which the positive and negative electrodes are cycled.</div></div>","PeriodicalId":343,"journal":{"name":"Joule","volume":"8 11","pages":"Pages 3072-3087"},"PeriodicalIF":38.6,"publicationDate":"2024-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142090465","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}

Electro-ag bypasses traditional photosynthesis, enabling food cultivation in non-arable urban centers, arid deserts, and even outer space environments. We offer a new strategy that improves energy efficiency by an order of magnitude compared with photosynthesis, along with essential guidance for developing electro-ag focused on staple crops, to maximize benefits for regions facing food insecurity.

Here, we provide a blueprint for available strategies to mitigate greenhouse gas (GHG) emissions from the primary production of battery-grade lithium hydroxide, cobalt sulfate, nickel sulfate, natural graphite, and synthetic graphite. Shifting to renewable electricity and electrifying heat for mining and refining operations and reagents production emerges as a promising avenue. Combined, these measures can reduce the GHG emissions intensity by 53%–86% for the analyzed production routes. However, these reductions may not achieve absolute decoupling of GHG emissions from the growing demand driven by the rollout of EVs. Bridging this gap may require additional strategies, including low-carbon haul trucks, electrification of processing equipment, reagents regeneration and/or substitution, alternative reducing agents, improvements in material recovery rates, or new and emerging production technologies.
