Single-crystalline layered oxides offer a promising solution to mitigate the rapid capacity decay observed in conventional polycrystalline nickel-rich oxide cathodes. However, achieving both morphological (large grain size) and structural (cation-disorder-free) control in single crystals remains challenging due to the trade-off between grain growth and phase stability, particularly at high-nickel contents. Here we report cation-disorder-free ultrahigh-nickel single-crystalline oxide cathodes with ~10-μm particle sizes, comparable to commercial secondary particles, that deliver high volumetric capacity and stable cycling. These single crystals withstand calendering and resist intra-granular cracking, achieving electrode densities of up to 77% of the theoretical crystal density. The improved stability is linked to reduced structural strain and modified glide behaviour due to the absence of cation disorder, emphasizing its critical role in chemomechanical behaviour. Additionally, gas evolution is reduced by a factor of 25, and the thermal onset temperature drops by more than 20 °C at ~4.5 V versus Li/Li+, underscoring superior safety features and energy density potential. Single-crystalline layered oxides can reduce capacity decay in nickel-rich cathodes, but controlling both the particle size and cation disorder is challenging. This work reports cation-disorder-free ~10-μm single-crystalline cathodes that deliver high volumetric capacity and cycle stability as well as improved safety.
单晶层状氧化物提供了一个很有前途的解决方案,以减轻在传统的多晶富镍氧化物阴极中观察到的快速容量衰减。然而,在单晶中实现形态(大晶粒尺寸)和结构(无阳离子无序)控制仍然具有挑战性,因为要在晶粒生长和相稳定性之间进行权衡,特别是在高镍含量时。在这里,我们报道了无阳离子无序的超高镍单晶氧化物阴极,其粒径为~10 μm,与商业二次粒子相当,具有高容量和稳定的循环。这些单晶可以承受压延和抗颗粒内开裂,实现高达理论晶体密度77%的电极密度。由于没有阳离子紊乱,稳定性的提高与结构应变的降低和滑动行为的改变有关,强调了其在化学力学行为中的关键作用。此外,与Li/Li+相比,在~4.5 V下,气体演化减少了25倍,热起温度降低了20°C以上,强调了优越的安全特性和能量密度潜力。

Negative pricing increases electricity use but challenges grid stability 负电价增加了用电量,但挑战了电网的稳定性

When electricity supply exceeds demand, consumers can be paid to use electricity through negative pricing. Simulations based on national surveys indicate that such pricing could double electricity loads in many US counties. However, market policies and grids must be carefully designed to avoid destabilizing the power grid with demand surges.
当电力供应超过需求时,可以通过负定价向消费者支付电费。基于全国调查的模拟表明,这样的定价可能会使美国许多县的电力负荷翻倍。然而,市场政策和电网必须精心设计,以避免需求激增导致电网不稳定。

The use of two-dimensional perovskite interlayers enables high efficiency in perovskite solar cells and modules but presents challenges for their long-term operational stability. Here we use a co-crystal engineering approach to improve the long-term stability of these devices. We use a neutral molecule, benzoguanamine, as a linker in low-dimensional perovskites, replacing conventional ionic molecules, and form a co-crystal. By applying this co-crystal layer onto the perovskite layer, we achieve power conversion efficiency of 23.4% in small-area solar cells, and 23.1% and 18.5% on solar modules with active areas of 9.0 cm2 and 48 cm2, respectively. The solar modules retain more than 95% and 98% of their initial efficiency after >5,000 h of 1-sun light soaking and >1,000 h of ultraviolet-ray exposure, respectively, at maximum power point conditions. They also retain more than 91% of their initial efficiency after >5,000 h of continuous thermal stress at 85 °C. Two-dimensional perovskites enable high efficiency in perovskite photovoltaics but compromise operational stability. Yaghoobi Nia et al. form two-dimensional perovskite co-crystals with neutral templating molecules, improving the stability of perovskite solar modules.
二维钙钛矿中间层的使用使钙钛矿太阳能电池和组件的效率很高,但对其长期运行稳定性提出了挑战。在这里,我们使用共晶工程方法来提高这些器件的长期稳定性。我们使用中性分子苯并鸟胺作为低维钙钛矿的连接剂,取代传统的离子分子,形成共晶。将该共晶层应用于钙钛矿层上,小面积太阳能电池的功率转换效率为23.4%,有效面积为9.0 cm2和48 cm2的太阳能组件的功率转换效率分别为23.1%和18.5%。在最大功率点条件下,太阳能组件分别在1-太阳光照5000小时和紫外线照射1000小时后保持了95%和98%以上的初始效率。在85°C的连续热应力下,在bbbb5000 h后,它们还能保持91%以上的初始效率。

Solar photovoltaics (PV) is entering a new era of multi-terawatt deployment, with 2 TW already in service and more than 75 TW predicted in many scenarios by 2050. This next era has been enabled by over five decades of cumulative advances in PV module cost reduction, performance and reliability. The current scale of deployment also introduces new needs, opportunities and challenges. In this Perspective we frame a path forwards based on learning, broadly defined as a combination of expansion of knowledge and advances through research and development, experience and collaboration. We discuss historical topics where learning has driven PV deployment until now, and emerging areas that are required to sustain high levels of future deployment. We expect progress to continue in terms of module price, performance and reliability, driven by advances in PV cell and module design, the emergence of tandem devices and increased focus on extending module lifetimes. Large-scale deployment also means large-scale sustainability and responsibility. We therefore posit that additional metrics, such as the impact on global CO2 emissions, resource consumption and design for reuse and recycling, will become increasingly important to the PV industry and provide opportunities for further learning. Solar photovoltaics is entering a multi-terawatt era, driven by decades of cost, performance and reliability gains. In this Perspective Alberi et al. discuss the role of historical and future learning, highlighting the increasing importance of sustainability considerations.
太阳能光伏发电(PV)正在进入一个多太瓦部署的新时代,到2050年,已经有2太瓦投入使用,预计在许多情况下将超过75太瓦。50多年来,光伏组件在降低成本、性能和可靠性方面的累积进步,使下一个时代成为可能。目前的部署规模也带来了新的需求、机遇和挑战。在这一视角下,我们构建了一条以学习为基础的前进道路,其广义定义为知识扩张与通过研发、经验和合作取得进步的结合。我们讨论了迄今为止推动光伏部署的历史主题,以及维持未来高水平部署所需的新兴领域。我们预计,在光伏电池和组件设计的进步、串联设备的出现以及对延长组件寿命的日益关注的推动下,组件的价格、性能和可靠性将继续取得进展。大规模部署也意味着大规模的可持续性和责任。因此,我们认为其他指标,如对全球二氧化碳排放的影响、资源消耗和设计的再利用和回收,将对光伏产业变得越来越重要,并提供进一步学习的机会。在几十年来成本、性能和可靠性提升的推动下,太阳能光伏发电正在进入一个多太瓦时代。在这个视角中,Alberi等人讨论了历史和未来学习的作用,强调了可持续性考虑的重要性日益增加。

Grid-scale corrosion-free Zn/Br flow batteries enabled by a multi-electron transfer reaction 由多电子转移反应实现的电网级无腐蚀Zn/Br液流电池

Flow batteries are promising for renewable energy storage due to their safety and scalability. Zinc/bromine flow batteries (Zn/Br) are popular due to their high energy densities and inexpensive electrolytes. However, they have a poor service life and lead to environmental harm as a result of the generated corrosive and volatile Br2. Here we introduce a Br2 scavenger to the catholyte, reducing the Br2 concentration to an acceptable level (~7 mM). The scavenger, sodium sulfamate (SANa), reacts rapidly with Br2 to form a mild product, N-bromo sodium sulfamate (Br-SANa; Br+). Additionally, the two-electron transfer reaction of Br-SANa/Br− (Br+/Br−) increases the energy density. We have developed a Zn/Br flow battery, paired with a Zn anode, that outperforms traditional Zn/Br flow batteries in energy density (152 Wh l−1 versus 90 Wh l−1) and cycle life (>600 versus 30 cycles), using a sulfonated polyetheretherketone membrane. We assembled a 5-kW stack that operated stably for over 700 cycles (~1,400 h). Using this reaction, we have built a large-scale battery system. Zinc-bromine flow batteries face challenges from corrosive Br2, which limits their lifespan and environmental safety. Here, the authors introduce sodium sulfamate as a Br2 scavenger, enabling a more durable and higher-energy-density Zn/Br flow battery suitable for large-scale operation.
液流电池由于其安全性和可扩展性,在可再生能源存储方面很有前景。锌/溴液流电池(Zn/Br)因其高能量密度和廉价的电解质而广受欢迎。然而,它们的使用寿命较差,并且由于产生腐蚀性和挥发性Br2而导致环境危害。我们在阴极液中加入Br2清除剂,将Br2浓度降低到可接受的水平(~7 mM)。清除剂氨基磺酸钠(SANa)与Br2迅速反应,生成温和的产物n -溴氨基磺酸钠(Br-SANa; Br+)。此外,Br- sana /Br−(Br+/Br−)的双电子转移反应增加了能量密度。我们开发了一种Zn/Br液流电池,搭配Zn阳极,使用磺化聚醚酮膜,在能量密度(152 Wh l - 1 vs 90 Wh l - 1)和循环寿命(bbb600 vs 30次循环)方面优于传统的Zn/Br液流电池。我们组装了一个5kw的堆栈,可以稳定运行700多个循环(约1,400小时)。利用这种反应,我们建立了一个大规模的电池系统。

Zinc/bromine flow batteries (Zn/Br) are popular due to their high energy densities and inexpensive electrolytes. However, they have a poor service life and lead to environmental harm as a result of the generated corrosive and volatile Br2. Here we introduce a Br2 scavenger to the catholyte, reducing the Br2 concentration to an acceptable level (~7 mM). The scavenger, sodium sulfamate (SANa), reacts rapidly with Br2 to form a mild product, N-bromo sodium sulfamate (Br-SANa; Br+). Additionally, the two-electron transfer reaction of Br-SANa/Br− (Br+/Br−) increases the energy density. We have developed a Zn/Br flow battery, paired with a Zn anode, that outperforms traditional Zn/Br flow batteries in energy density (152 Wh l−1 versus 90 Wh l−1) and cycle life (>600 versus 30 cycles), using a sulfonated polyetheretherketone membrane. We assembled a 5-kW stack that operated stably for over 700 cycles (~1,400 h). Using this reaction, we have built a large-scale battery system.
