Electrochemical reduction of CO2 from flue gas shows promise for producing chemicals and fuels from waste streams, but its implementation is challenged by the presence of SO2 impurities. Research now demonstrates a catalyst that effectively converts CO2 to multi-carbon products while tolerating SO2 impurities, advancing the feasibility of industrial CO2 utilization.

Cathodes for next-generation batteries are pressed for higher voltage operation (≥4.5 V) to achieve high capacity with long cyclability and thermal tolerance. Current cathodes fail to meet these requirements owing to structural and electrochemical strains at high voltages, leading to fast capacity fading. Here we present a cathode with a coherent architecture ranging from ordered to disordered frameworks with concentration gradient and controllable Ni oxidation activities, which can overcome voltage ceilings imposed by existing cathodes. This design enables simultaneous high-capacity and high-voltage operation at 4.5 V without capacity fading, and up to 4.7 V with negligible capacity decay. Multiscale diffraction and imaging techniques reveal the disordered surface is electrochemically and structurally indestructible, preventing surface parasitic reactions and phase transitions. Structural coherence from ordering to disordering limits lattice parameter changes, mitigating lattice strain and enhancing morphological integrity. The dual-gradient design also notably improves thermal stability, driving the advancement of high-performance cathode materials. Battery cathodes tend to degrade severely during high-voltage operations. Here the authors present a cathode design with a structurally coherent architecture, ranging from ordered to disordered frameworks, that addresses this issue.
下一代电池的阴极需要更高的工作电压（≥4.5 V），以实现高容量、长循环性和耐热性。目前的阴极无法满足这些要求，因为在高电压下会产生结构和电化学应变，导致容量快速衰减。在这里，我们提出了一种具有从有序框架到无序框架的连贯结构、浓度梯度和可控镍氧化活性的阴极，它可以克服现有阴极施加的电压上限。这种设计可在 4.5 V 电压下同时实现高容量和高电压运行，且不会出现容量衰减，在高达 4.7 V 电压下，容量衰减可忽略不计。多尺度衍射和成像技术揭示了无序表面在电化学和结构上的不可破坏性，防止了表面寄生反应和相变。从有序到无序的结构一致性限制了晶格参数的变化，减轻了晶格应变，增强了形态完整性。双梯度设计还显著提高了热稳定性，推动了高性能阴极材料的发展。

Transportation is undergoing rapid electrification, with electric buses at the forefront of public transport, especially in China. This transition, however, could strain electricity grids. Using a large-scale dataset with over 200 million global positioning system records from 20,992 buses in Beijing, we explore the technical, economic and environmental implications of transforming public transport depots into renewable energy hubs. Here we show that solar photovoltaic reduces the grid’s net charging load by 23% during electricity generation periods and lowers the net charging peak load by 8.6%. Integrating energy storage amplifies these reductions to 28% and 37.4%, respectively. Whereas unsubsidized solar photovoltaic yields profit 64% above costs, adding battery storage cuts profits to 31% despite offering grid benefits. Negative marginal abatement gains for CO2 emissions underscore the economic sustainability. Our findings provide a model for cities worldwide to accelerate their commitments towards sustainable transport and energy systems. Electric bus charging could strain electricity grids with intensive charging. Here the authors present a data-driven framework to transform bus depots into grid-friendly profitable energy hubs using solar photovoltaic and energy storage systems.

Rapidly building utility-scale energy infrastructure requires not only public support but also political will across levels of government. Here we use a conjoint experiment to assess preferences for large-scale energy projects among residents and local elected officials in Pennsylvania—a key transition state with high solar potential where siting authority rests at the local level. We find that residents prefer solar to other energy projects, and job creation and cooperative community ownership are associated with increased support. Public and elected official support decreases when projects are owned by foreign companies. We find limited partisan differences in preferences, suggesting a path towards bipartisan support for such projects. Elected officials misperceive their constituents’ preferences, underestimating support for renewable energy and the importance of job creation. As local officials are key decision-makers regarding infrastructure development, their preferences and perceptions of constituents’ preferences may dictate which energy projects are approved and what community benefits they deliver. Pennsylvanians support energy infrastructure projects that use solar, create jobs and are community owned. Elected officials misperceive constituents’ preferences, underestimating support for renewable energy and job creation.

All-solid-state lithium batteries typically employ heterogeneous composite cathodes where conductive additives are introduced to improve mixed conduction. These electrochemically inactive additives are not fully compatible with layered oxide cathodes that undergo large volume change, significantly reducing battery energy density and cycle life. Here we propose a cathode homogenization strategy by cold pressing a zero-strain cathode material with efficient mixed conduction throughout the (dis)charge process. Li1.75Ti2(Ge0.25P0.75S3.8Se0.2)3 possesses considerable Li+/electronic conductivity of 0.22/242 mS cm−1 when fully charged, increasing monotonically to 0.66/412 mS cm−1 when fully discharged. It delivers a specific capacity of 250 mAh g−1 and undergoes a 1.2% volume change. Homogeneous cathodes composed of 100% Li1.75Ti2(Ge0.25P0.75S3.8Se0.2)3 enable room-temperature all-solid-state lithium batteries to achieve a cycle life of over 20,000 cycles at 2.5 C with a specific capacity retention of 70% and a high energy density of 390 Wh kg−1 at the cell level at 0.1 C. This cathode homogenization strategy contrasts to the conventional cathode heterogeneous design, potentially improving the viability of all-solid-state lithium batteries for commercial applications. Solid-state lithium batteries typically utilize heterogeneous composite cathodes with conductive additives, which limit energy density and cycle life. Here the authors present a cathode material that exhibits efficient mixed conduction and near-zero volume change during cycling, thereby improving battery performance.
全固态锂电池通常采用异质复合阴极，其中引入了导电添加剂以改善混合传导。这些电化学不活跃的添加剂与体积变化较大的层状氧化物阴极并不完全兼容，从而大大降低了电池的能量密度和循环寿命。在此，我们提出了一种阴极均匀化策略，即在整个（去）充电过程中冷压一种具有高效混合传导能力的零应变阴极材料。Li1.75Ti2(Ge0.25P0.75S3.8Se0.2)3具有相当高的锂+/电导率，完全充电时为0.22/242 mS cm-1，完全放电时单调增加到0.66/412 mS cm-1。它的比容量为 250 mAh g-1，体积变化率为 1.2%。由 100% Li1.75Ti2(Ge0.25P0.75S3.8Se0.2)3组成的均质正极使室温全固态锂电池在 2.5 摄氏度下的循环寿命超过 20,000 次，比容量保持率达 70%，在 0.1 摄氏度下的电池能量密度高达 390 Wh kg-1。这种阴极均匀化策略与传统的阴极异质设计形成鲜明对比，有可能提高全固态锂电池在商业应用中的可行性。
