Although the migration of lithium cations is known to induce phase transition from α-phase to δ-phase in perovskites, reports of long-term device stability present apparent contradictions. Here we show that, under dark/light alternating conditions, lithium migration induces a rapid degradation of the α-phase perovskite. This degradation is not observed under continuous light-only or dark-only conditions commonly used within the field to test the devices. To address the instability under dark/light cycling, we replace the lithium dopant with a methylammonium dopant. Importantly, we show no unreacted methylammonium dopant in the hole-transport layer film different to the lithium dopant, hinting at a better device stability. We achieve an efficiency of 26.1% (25.6% certified) and <i>T</i><sub>95</sub> lifetimes (that is, time for the device efficiency to decay to 95% of its initial value) of over 1,200 h of continuous light–dark cycling (ISOS-LC-1 certified) and 3,000 voltage-on/off cycles, conditions that are relevant to real-world operation.</p>","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":"127 1","pages":""},"PeriodicalIF":56.7,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144924128","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 partially ordered structure stabilizes the delithiated cathode at a high cut-off voltage, offering strain-free characteristics, with structural variations along both the <i>a</i> and <i>c</i> axes limited to approximately 1%. Consequently, the cathode can operate at 4.6 V while delivering a reversible capacity comparable to that of Ni-rich Li(Ni<sub>0.8</sub>Co<sub>0.1</sub>Mn<sub>0.1</sub>)O<sub>2</sub>. Moreover, a high capacity is maintained during long-term and high-voltage cycling in full cells with exceptional thermal safety.

A major technical challenge is the reversible chemical oxidation of the reduced organics by atmospheric O2, which can lower energy efficiency and capture capacity. Here we report the development of a hybrid phenazine flow cell system that uses a pH-swing direct air capture (DAC) process, utilizing redox-active cyclic poly(phenazine sulfide) fabricated solid electrodes. The system maintains a separation between the air and the O2-sensitive reduced phenazine, enabling stable and effective CO2 capture from gas mixtures containing O2. This flow cell demonstrated substantial oxygen compatibility, exhibiting a coulombic efficiency of 99% and requiring only 73 kJ mol−1 CO2 for simulated flue gas and 104 kJ mol−1 CO2 for DAC. The strategy of isolating vulnerable species offers an efficient pathway for DAC and may be broadly applicable to avoiding undesirable side reactions in other electrochemical devices. Electrochemical CO2 capture is hindered by the oxidation of redox-active organic molecules by O2, affecting energy efficiency and capacity. Here the authors develop a flow cell in which the O2-sensitive components are isolated from O2, achieving 99% coulombic efficiency with low energy requirements.","PeriodicalId":19073,"journal":{"name":"Nature Energy","volume":"10 9","pages":"1146-1154"},"PeriodicalIF":60.1,"publicationDate":"2025-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144901083","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}
