A scalable battery recycling strategy to recover and regenerate solid electrolytes and cathode materials in spent all solid-state batteries, reducing energy consumption and greenhouse gases. With the rapidly increasing ubiquity of lithium-ion batteries (LIBs), sustainable battery recycling is a matter of growing urgency. The major challenge faced in LIB sustainability lies with the fact that the current LIBs are not designed for recycling, making it difficult to engineer recycling approaches that avoid breaking batteries down into their raw materials. Thus, it is prudent to explore new approaches to both fabricate and recycle next-generation batteries before they enter the market. Here, we developed a sustainable design and scalable recycling strategy for next-generation all solid-state batteries (ASSBs). We use the EverBatt model to analyze the relative energy consumption and environmental impact compared to conventional recycling methods. We demonstrate efficient separation and recovery of spent solid electrolytes and electrodes from a lithium metal ASSB and directly regenerate them into usable formats without damaging their core chemical structure. The recycled materials are then reconstituted to fabricate new batteries, achieving similar performance as pristine ASSBs, completing the cycle. This work demonstrates the first fully recycled ASSB and provides critical design consideration for future sustainable batteries.
一种可扩展的电池回收策略,用于回收和再生废旧固态电池中的固体电解质和正极材料,减少能源消耗和温室气体排放。随着锂离子电池(lib)的迅速普及,电池的可持续回收是一个日益紧迫的问题。锂离子电池可持续性面临的主要挑战在于,目前的锂离子电池不是为回收而设计的,因此很难设计出避免将电池分解为原材料的回收方法。因此,在下一代电池进入市场之前,探索制造和回收新方法是谨慎的。在这里,我们为下一代全固态电池(assb)开发了可持续设计和可扩展的回收策略。我们使用everbat模型来分析与传统回收方法相比的相对能源消耗和环境影响。我们展示了从锂金属ASSB中有效分离和回收废固体电解质和电极,并直接将其再生为可用的形式,而不会破坏其核心化学结构。然后将回收的材料重新合成以制造新的电池,达到与原始assb相似的性能,完成循环。这项工作展示了第一个完全回收的ASSB,并为未来的可持续电池提供了关键的设计考虑。

Building better dual-ion batteries 制造更好的双离子电池
IF 4.3 Q3 ENERGY & FUELS Pub Date : 2020-07-01 DOI: 10.1557/mre.2020.38
K. Kravchyk, M. Kovalenko
This perspective article summarizes the operational principles of dual-ion batteries and highlights the main issues in the interpretation and reporting of their electrochemical performance. Secondary dual-ion batteries (DIBs) are emerging stationary energy storage systems that have been actively explored in view of their low cost, high energy efficiency, power density, and long cycling life. Nevertheless, a critical assessment of the literature in this field points to numerous inaccuracies and inconsistencies in reported performance, primarily caused by the exclusion of the capacity of used electrolytes and the use of non-charge-balanced batteries. Ultimately, these omissions have a direct impact on the assessment of the energy and power density of DIBs. Aiming to secure further advancement of DIBs, in this work, we critically review current research pursuits and summarize the operational mechanisms of such batteries. The particular focus of this perspective is put on highlighting the main issues in the interpretation and reporting of the electrochemical performance of DIBs. To this end, we survey the prospects of these stationary storage systems, emphasizing the practical hurdles that remain to be addressed.
这篇前瞻性文章总结了双离子电池的工作原理,并强调了解释和报告其电化学性能的主要问题。二次双离子电池(DIBs)是一种新兴的固定式储能系统,由于其低成本、高能效、功率密度和长循环寿命,已被积极探索。然而,对该领域文献的批判性评估指出,报告的性能存在许多不准确和不一致之处,主要是由于排除了使用过的电解质的容量和使用非电荷平衡电池造成的。最终,这些遗漏会对DIB的能量和功率密度的评估产生直接影响。为了确保DIB的进一步发展,在这项工作中,我们批判性地回顾了当前的研究成果,并总结了这种电池的运行机制。这一观点的重点是强调DIB电化学性能的解释和报告中的主要问题。为此,我们调查了这些固定存储系统的前景,强调了仍有待解决的实际障碍。

Sustainable integration of human activities into the global ecosystem 人类活动可持续地融入全球生态系统
IF 4.3 Q3 ENERGY & FUELS Pub Date : 2020-07-01 DOI: 10.1557/mre.2020.27
P. Lorge
The sustainable integration of human activities into the global ecosystem is discussed, pointing out fatal anthropogenic heat as a major ecological problem and proposing global technical and economical solutions. For human sake, we must get out of the “thermal age” and implement the “electroprotonic era” as soon as possible. Contrary to thermal power, electroprotonic is sustainable and can be produced by photoenzymatic systems, a cheap way to produce hydrogen (H_2) or ammonia (NH_3). We can accelerate the advent of this new era if we re-integrate external costs generated by thermal energies into their final prices. The author is leading the H2GREEN project in Belgium as an entrepreneur for more than a decade, which develops the photoenzymatic production of dihydrogen from water. The aim of the H2GREEN project is to contribute to the launch of a low-cost, renewable Hydrogen-based local economy as an energy carrier. Among the difficulties of this launch, the most important is certainly the lack of competitiveness due to the unfair competition of carbon products that externalizes their costs (CO_2, oil spills, lethal pollution, armed conflicts, political oppression, foreign dependence, etc.).
讨论了人类活动与全球生态系统的可持续整合,指出致命的人为高温是一个主要的生态问题,并提出了全球技术和经济解决方案。为了人类,我们必须尽快走出“热时代”,实现“电质子时代”。与热能相反,电质子是可持续的,可以通过光酶系统生产,这是一种生产氢气(H_2)或氨(NH_3)的廉价方法。如果我们将热能产生的外部成本重新整合到最终价格中,我们可以加快这个新时代的到来。作者作为一名企业家在比利时领导H2GREEN项目十多年,该项目开发了用光酶法从水中生产二氢。H2GREEN项目的目的是促进低成本、可再生的氢基地方经济作为能源载体的启动。在这次发射的困难中,最重要的当然是由于碳产品的不公平竞争而缺乏竞争力,这种竞争将其成本外部化(二氧化碳、石油泄漏、致命污染、武装冲突、政治压迫、对外依赖等)。

Liquid-state pyroelectric energy harvesting 液态热释电能量采集
IF 4.3 Q3 ENERGY & FUELS Pub Date : 2020-07-01 DOI: 10.1557/mre.2020.39

A liquid-state pyroelectric energy harvester is described and a remarkable capacity to convert a thermal gradient into electrical energy is demonstrated. Increasing the sustainability of energy generation can be pursued by harvesting extremely low enthalpy sources: low temperature differences between cold and hot reservoirs are easily achieved in every industrial process, both at large and small scales, in plants as well as in small appliances, vehicles, natural environments, and human bodies. This paper presents the assessment and efficiency estimate of a liquid-state pyroelectric energy harvester, based on a colloid containing barium titanate nanoparticles and ferrofluid as a stabilizer. The liquid is set in motion by an external pump to control velocity, in a range similar to the one achieved by Rayleigh–Bénard convection, and the colloid reservoir is heated. The colloid is injected into a Fluorinated Ethylene Propylene pipe where titanium electrodes are placed to collect electrical charges generated by pyroelectricity on the surface of the nanoparticles, reaching 22.4% of the ideal Carnot efficiency of a thermal machine working on the same temperature drop. The maximum extracted electrical power per unit of volume is above 7 mW/m^3 with a Δ T between electrodes of 3.9 K.
描述了一种液态热释电能量收集器,并证明了将热梯度转换为电能的显着能力。提高能源生产的可持续性可以通过收集极低焓源来实现:冷热储层之间的低温差异在每个工业过程中都很容易实现,无论是大型还是小型,无论是在工厂还是在小型电器、车辆、自然环境和人体中。本文介绍了一种基于含钛酸钡纳米颗粒胶体和铁磁流体作为稳定剂的液态热释电能量收集器的评价和效率估计。液体通过一个外部泵来控制流速,流速的范围与瑞利-巴姆纳德对流所达到的流速相似,同时胶体储层被加热。将胶体注入氟化乙烯丙烯管中,在管中放置钛电极来收集纳米颗粒表面由热电产生的电荷,在相同的温度降下,达到热机理想卡诺效率的22.4%。每单位体积提取的最大电功率超过7 mW/m^3,电极之间的Δ T为3.9 K。

In the rural areas of the eastern Amhara region where livelihoods are predominantly based on agriculture with almost all the rural people earning their income from agriculture, awareness toward clean energy, and efficient appliances is at a very infant stage. As an indication, the research comes up with energy utilization is mainly of biomass-based with traditional stoves of very low efficiency. However, the future demand of the community toward the clean and improved efficient appliances has got a better preference over other energy technologies. Regarding the factor in determining the energy and energy appliance type choice, accessibility is found as the major reason.}The type of energy sources and energy technologies utilized for cooking and lighting have their own effect on health, environmental degradation, and overall economic development. Therefore, the primary objective of this study was to analyze the general trend of household energy source and energy technology utilization in rural areas of the Eastern Amhara region. The study utilized primary and secondary data collected over stratified systematically sampled households and from energy experts in the area. The study examined the utilization of various forms of energy and energy technology for the most common household energy-intensive processes (injera baking and stew cooking) as well as lighting. The development of different estimates across the whole population of the study region to indicate the relations among different factors was done through different statistical approaches; and the finding of the analysis revealed that 57.7% of the energy share is biomass-based firewood from which 99.5% of this source was used only for food preparation. The two main determinant factors of the community in selecting the energy types are found to be accessibility and health impact.
在阿姆哈拉州东部的农村地区,那里的生计主要以农业为基础,几乎所有的农村人都从农业中赚取收入,对清洁能源和高效电器的认识还处于初级阶段。研究表明,能源利用主要是以生物质为基础的传统炉灶,效率很低。然而,与其他能源技术相比,社区对清洁和改进高效电器的未来需求得到了更好的偏好。关于决定能源和能源设备类型选择的因素,可及性是主要原因。}用于烹饪和照明的能源类型和能源技术对健康、环境退化和整体经济发展有其自身的影响。因此,本研究的主要目的是分析阿姆哈拉东部农村地区家庭能源和能源技术利用的总体趋势。该研究利用了从该地区的能源专家那里收集的、经过分层系统抽样的家庭的主要和次要数据。这项研究考察了各种形式的能源和能源技术在最常见的家庭能源密集型工艺(injera烘焙和炖菜烹饪)以及照明中的利用情况。通过不同的统计方法,对研究区域的全体人口进行了不同的估计,以表明不同因素之间的关系;分析结果表明,57.7%的能源份额是基于生物质的木柴,其中99.5%的能源仅用于食品制备。社区在选择能源类型时的两个主要决定因素是可获得性和健康影响。

We report a significant advance in thermally insulating transparent materials: silica-based monoliths with controlled porosity which exhibit the transparency of windows in combination with a thermal conductivity comparable to aerogels. The lack of transparent, thermally insulating windows leads to substantial heat loss in commercial and residential buildings, which accounts for ~4.2% of primary US energy consumption annually. The present study provides a potential solution to this problem by demonstrating that ambiently dried silica aerogel monoliths, i.e., ambigels, can simultaneously achieve high optical transparency and low thermal conductivity without supercritical drying. A combination of tetraethoxysilane, methyltriethoxysilane, and post-gelation surface modification precursors were used to synthesize ambiently dried materials with varying pore fractions and pore sizes. By controlling the synthesis and processing conditions, 0.5–3 mm thick mesoporous monoliths with transmittance >95% and a thermal conductivity of 0.04 W/(m K) were produced. A narrow pore size distribution, <15 nm, led to the excellent transparency and low haze, while porosity in excess of 80% resulted in low thermal conductivity. A thermal transport model considering fractal dimension and phonon-boundary scattering is proposed to explain the low effective thermal conductivity measured. This work offers new insights into the design of transparent, energy saving windows.
我们报道了隔热透明材料的重大进展:具有可控孔隙率的二氧化硅基单片,其表现出窗口的透明度和与气凝胶相当的热导率。由于缺乏透明隔热窗户,商业和住宅建筑的热损失很大,每年约占美国一次能源消耗的4.2%。本研究为这个问题提供了一个潜在的解决方案,证明了环境干燥的二氧化硅气凝胶单片,即环境凝胶,可以在不进行超临界干燥的情况下同时实现高光学透明度和低导热性。四乙氧基硅烷、甲基三乙氧基硅烷和凝胶化后表面改性前体的组合用于合成具有不同孔隙分数和孔径的环境干燥材料。通过控制合成和加工条件,制备了厚度为0.5–3 mm、透射率>95%、热导率为0.04 W/(m K)的中孔单体。孔径分布窄,<15nm,导致优异的透明度和低雾度,而孔隙率超过80%导致低热导率。提出了一个考虑分形维数和声子边界散射的热输运模型来解释测量的低有效热导率。这项工作为透明节能窗户的设计提供了新的见解。
