Here we design a thermal-switching material with high switching ratio from thermal conduction to thermal insulation state to address this predicament. The designed thermal-switching material exhibits a wide temperature range for heat conduction (1.33 W m−1 K−1 at room temperature) and can transform to an adiabatic state within 30 s (0.1 W m−1 K−1 at around 100 °C) when heated. When applied as cell-to-cell interlayers for a module with four 50 Ah nickel–cobalt–manganese lithium-ion cells, the material not only ensures a uniform temperature distribution under normal working conditions, but more importantly prevents 80% of the heat transmission from thermal runaway, effectively avoiding catastrophic battery explosion. We believe that this thermally responsive material design will ensure safety and high performance throughout the lifespan of high-energy-density battery modules. Smart temperature-responsive materials could enhance battery thermal safety management; however, current designs lack the necessary responsiveness for both performance and safety. Here the authors demonstrate a material that swiftly transitions from thermal transmission to isolation during thermal runaway in battery modules, thereby ensuring battery safety.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":null,"pages":null},"PeriodicalIF":49.7,"publicationDate":"2024-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141251660","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}

However, existing polybenzimidazole (PBI)-based PEM fuel cells face challenges due to the instability of proton transport above 160 °C. Here we report a PEM composed of para-PBI (p-PBI) and cerium hydrogen phosphate (CeHP) that can be used in a fuel cell at up to 250 °C. During fabrication, echinoid-shaped CeHP particles form a well-dispersed and interconnected self-assembled network within the PBI matrix (SAN–CeHP–PBI), allowing them to outperform p-PBI and conventional CeHP–PBI PEMs in terms of proton transport above 200 °C. We report a SAN–CeHP–PBI-based fuel cell that reaches a maximum power density of 2.35 W cm−2 (at 250 °C in dry H2/O2) with negligible degradation over 500 h during thermal cycling (at 160–240 °C, H2/air). SAN–CeHP–PBI also demonstrates excellent CO tolerance, showing promise for integration with liquid hydrogen carrier systems. High-temperature operation of polymer electrolyte membrane fuel cells has some advantages but is also challenging due to the instability of proton transport above 160 °C. Here the authors report a polymer electrolyte membrane comprising well-dispersed and interconnected cerium hydrogen phosphate particles within a polymer matrix that performs well in a fuel cell at up to 250 °C.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":null,"pages":null},"PeriodicalIF":49.7,"publicationDate":"2024-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141246609","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}

Community solar, where multiple households buy solar from shared systems, could make solar more accessible by reducing initial costs and removing adoption barriers for renters and multifamily building occupants. Here we test whether community solar has expanded solar access in the United States. On the basis of a sample of 11 states, we find that community solar adopters are about 6.1 times more likely to live in multifamily buildings than rooftop solar adopters, 4.4 times more likely to rent and earn 23% less annual income. We do not find that community solar expands access in terms of race. These differences are driven, roughly evenly, by inherent differences between the two solar products and by policies to promote low-income community solar adoption. The results suggest that alternative solar products can expand solar access and that policy could augment such benefits. Drawing from data on 11 US states, here the authors find evidence to suggest that community solar and other alternative solar products have the potential to expand solar access among lower-income and renter households.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":null,"pages":null},"PeriodicalIF":49.7,"publicationDate":"2024-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141236025","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}

Between 2017 and 2021, they surged tenfold, exceeding €80 tCO2−1 and reshaping investment decisions across the electricity and industry sectors. What has driven this increase is an open question. While it coincided with two significant reforms tightening the cap (‘MSR reform’ and ‘Fit for 55’), we argue that a reduced supply of allowances alone cannot fully explain the price rise. A further crucial aspect is that actors must have become more farsighted as the reform signalled policymakers’ credible long-term commitment to climate targets. This is consistent with model results that show historic prices can be better explained with myopic actors, whereas explaining prices after the reforms requires actors to be farsighted. To underline the role of credibility, we test what would happen if a crisis undermines policy credibility such that actors become myopic again, demonstrating that carbon prices could plummet and endanger the energy transition. EU emissions trading system carbon prices have surged since 2017. Here the authors consider sources of this increase and note that increased foresight driven by stronger commitment to climate targets has played a role. Prices also run the risk of dropping if policy credibility is undermined.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":null,"pages":null},"PeriodicalIF":49.7,"publicationDate":"2024-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s41560-024-01505-x.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141177381","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, the efficiency of these solar cells is challenged by severe charge losses and complex defects. Here we reveal through a data-driven correlation analysis that the dominant deep defect in CZTSSe exhibits a donor character. We further propose that incomplete cation exchange in the multi-step crystallization reactions of CZTSSe is the kinetic mechanism responsible for the defect formation. To facilitate the cation exchange, we introduce a multi-elemental alloying approach aimed at weakening the metal–chalcogen bond strength and the stability of intermediate phases. This strategy leads to a significant reduction in charge losses within the CZTSSe absorber and to a total-area cell efficiency of 14.6% (certified at 14.2%). Overall, these results not only present a significant advancement for kesterite solar cells but could also help identify and regulate defects in photovoltaic materials.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":null,"pages":null},"PeriodicalIF":56.7,"publicationDate":"2024-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141177380","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}
