Over the past decade, an abundance of work has been carried out at ambient temperature, and high CO2E rates and product selectivities have been achieved. With scaling of CO2E technologies underway, greater discourse surrounding heat management and the viable operating temperatures of larger systems is important. In this Perspective we argue that, owing to the energy inefficiency of electrolysers, heat generation in CO2E stacks will favour operating temperatures of between 40 and 70 °C, far from the ambient temperatures used so far. Such elevated temperatures put further pressure on catalyst and membrane stability and on the stack design. On the other hand, elevated temperatures could alleviate challenges in salt precipitation, water management and high cell voltages, aiding the technology. We reflect on these aspects and discuss the opportunities for waste heat valorization to increase the economic feasibility of the process.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":"43 1","pages":""},"PeriodicalIF":56.7,"publicationDate":"2025-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143880489","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}

{"title":"Rethinking molecular O2","authors":"Xinru Li","doi":"10.1038/s41560-025-01772-2","DOIUrl":"https://doi.org/10.1038/s41560-025-01772-2","url":null,"abstract":"Compared to conventional metal oxide cathodes found in Li-ion batteries, Li-rich layered oxides introduce an additional charge storage mechanism that involves not just transition metals, but also lattice oxygen, known as anionic redox. These dual (cationic and anionic) redox processes enhance Li-ion utilization and increase capacity, making these materials promising candidates for next-generation batteries. However, commercialization is limited by rapid performance degradation mainly related to complex oxygen evolution processes, affecting both capacity and discharge voltage. In particular, voltage decay, which is characterized by a gradual decline in discharge voltage, reduces the battery’s practical energy density and efficiency. Despite extensive debate, the role of anions in the redox processes is still uncertain. The most recent focus is on the involvement of trapped molecular O2, based on high-resolution resonant X-ray inelastic scattering (RIXS) research. Now, Jean-Marie Tarascon and colleagues in France, China, and Russia challenge the prevailing view, arguing that molecular O2 is not a direct product of the redox activity of the Li-stoichiometric or Li-rich layered oxides, raising questions about identifying speciation using RIXS.The researchers survey RIXS data from various oxide-based cathodes under different conditions, suggesting that molecular O2 is not formed through electrochemical redox reactions but rather is due to excitation by the RIXS measurement. The results reveal that molecular O2 signals appear not only in Li-rich oxides capable of anionic oxygen redox, but also in O-redox-inactive materials like Li-stoichiometric layered and spinel oxides, indicating no correlation with voltage decay. By clarifying the origin of molecular O2, this study provides valuable insights into oxygen redox reactions in Li-rich layered oxide cathodes and offers guidelines for developing more stable and efficient cathode materials for Li-ion batteries.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":"33 1","pages":""},"PeriodicalIF":56.7,"publicationDate":"2025-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143872545","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}
