The conductive additive and binder domain (CBD) is an essential component of lithium-ion battery electrodes. It enhances the electrical connectivity and mechanical stability within the solid electrode matrix. The CBD aggregate exhibits inner porosity that significantly impacts ion transport within the electrode. Thus, the spatial distribution of CBD and its morphology play a critical role for ion transport pathways within the electrode. In order to quantify the extent of this influence, we employ high-resolution focused ion beam/scanning electron microscopy (FIB-SEM) imaging and isolate regions with just solid CBD and pore. This enables us to quantitatively correlate the CBD morphology with physical transport parameters and present a function that describes the relationship between CBD porosity and its ionic conductivity. Through our work, we provide insights into the CBD microstructure for use in future continuum-scale models.
导电添加剂和粘结剂域(CBD)是锂离子电池电极的重要组成部分。它增强了固体电极基体内的电连通性和机械稳定性。CBD聚集体表现出内部孔隙,显著影响离子在电极内的传输。因此,CBD的空间分布及其形态对电极内离子传输途径起着至关重要的作用。为了量化这种影响的程度,我们采用高分辨率聚焦离子束/扫描电子显微镜(FIB-SEM)成像并分离只有固体CBD和孔隙的区域。这使我们能够定量地将CBD的形态与物理运输参数联系起来,并提出一个描述CBD孔隙率与其离子电导率之间关系的函数。通过我们的工作,我们提供了对CBD微观结构的见解,用于未来的连续尺度模型。

Using ultra-thick electrodes could be a promising strategy to increase the energy density of lithium-ion batteries. However, thickening electrodes leads to higher resistance for electron/ion transportation within the electrodes, resulting in a decrease in capacity and power. In addition, binder migration, which is a problem in the slurry coating process, becomes more pronounced. In this paper, we propose a novel fibrous conductive additive, conductive and binding fibers (CBFs), which are simply fabricated by combining two cost-effective materials—acetylene black and polyvinylidene fluoride—using electrospinning. We also report techniques to prepare CBF-based electrodes (CBFEs) using a solvent-free dry process. Morphological and electrochemical evaluations of the CBFEs (mass loading: 100 mg cm−2) reveal that the unique electrode structure formed by CBFs leads to high battery performance. The continuous efficient conductive networks formed by CBFs prevent electrical isolation of the active material particles. In addition, the CBFs serve as frameworks in electrodes because of their adhesion, forming larger pores (∼1 μm) and enhancing ion transport. Consequently, CBFEs achieve a discharge capacity of 91.9 mA h gAM−1 at 0.2C—a 1.6-fold improvement over conventional electrodes. The features of CBFs, which combine both conductivity and binding properties, enable the realization of a low-cost and high-performance electrode.
使用超厚电极可能是提高锂离子电池能量密度的一种很有前途的策略。然而,增厚的电极会导致电极内电子/离子传输的更高电阻,从而导致容量和功率的下降。此外,粘结剂迁移,这是一个问题,在浆料涂层过程中,变得更加明显。本文提出了一种新型的纤维导电添加剂——导电结合纤维(CBFs),该纤维是由两种具有成本效益的材料乙炔黑和聚偏氟乙烯静电纺丝合成的。我们还报告了使用无溶剂干燥工艺制备cbf基电极(CBFEs)的技术。对CBFs(质量负载为100 mg cm−2)的形态学和电化学评价表明,CBFs形成的独特电极结构导致了高性能的电池。由CBFs形成的连续高效导电网络防止了活性物质颗粒的电隔离。此外,由于CBFs具有粘附性,因此可以在电极中充当框架,形成更大的孔(~ 1 μm)并增强离子传输。因此,CBFEs在0.2℃下的放电容量为91.9 mA h gAM−1,比传统电极提高了1.6倍。CBFs结合了导电性和结合性的特点,使其能够实现低成本和高性能的电极。

The increasing demand for Lithium-ion batteries (LIBs) in several applications has led to a substantial rise in their production, posing risks in the supply of critical raw materials (CRM, e.g.: Li, Ni, Co). Additionally, improper disposal of end-of-life batteries can lead to environmental pollution and loss of technological value stressing the necessity for sustainable recycling. Current methods involve shredding batteries into a black mass, further processed via pyrometallurgy (energy-intensive) and/or hydrometallurgy with inorganic acids (environmentally hazardous) to recover CRMs. A more refined approach to LIBs recycling includes the dismantling and the sorting of their components, allowing for a targeted extraction.
The spent cathodes recycling process here presented involves the simultaneous delamination from the current collector and the leaching (>95 %) of the cathode active material (CAM) in a citric acid solution, enabling also the recovery of Polyvinylidene fluoride (PVDF) and Carbon filler as unleached residues, which can be used as a composite binder for new electrodes manufacturing. Lastly, metals are recovered with high yields (>85 %) as precursors, used to resynthesise fresh CAM and close the recycling loop. To validate the proposed strategy, the recycled CAM was used in a new cathode manufacturing followed by its functional characterization in a half-cell configuration, achieving high coulombic efficiencies (>99.2 %) and satisfying specific capacities upon cycling (initial capacity: 115 mAh g−1).
锂离子电池(lib)在一些应用领域的需求不断增加,导致其产量大幅增加,对关键原材料(CRM,例如:Li, Ni, Co)的供应构成风险。此外,对报废电池的不当处理会导致环境污染和技术价值的丧失,这强调了可持续回收的必要性。目前的方法包括将电池粉碎成黑色块,通过火法冶金(能源密集型)和/或无机酸湿法冶金(对环境有害)进一步处理,以回收crm。一种更精细的lib回收方法包括拆卸和分类其成分,允许有针对性的提取。本文介绍的废阴极回收过程包括从集流器中同时分层和在柠檬酸溶液中浸出阴极活性物质(CAM) (> 95%),还可以回收聚偏氟乙烯(PVDF)和碳填料作为未脱出的残留物,它们可以用作制造新电极的复合粘合剂。最后,金属以高收率(> 85%)作为前体回收,用于重新合成新鲜CAM并关闭循环。为了验证所提出的策略,将回收的CAM用于新的阴极制造,然后在半电池配置中对其进行功能表征,获得了高库仑效率(> 99.2%)和循环时满足的特定容量(初始容量:115 mAh g−1)。

The constitutive mechanical behavior of the individual components in Lithium-ion cells has a fundamental influence on the development of internal electrical short-circuits in crash-relevant load scenarios. These short circuits can result in explosive, thermally unstable states (so called thermal runaways). The experimental characterization of mechanical properties of single components but also of entire cells is therefore a central aspect in the safety-related assessment of battery systems. This paper presents and compares experimental results of the mechanical characterization of individual cell components as well as whole pouch-cells under different loading patterns. Especially, the different mechanical behavior of the active materials NMC and graphite was investigated in dry and wet conditions. In compression tests, the presence of the electrolyte reduced the stress levels by about 100 % for the graphite layered anode (Cu) and by about 20 % for the NMC layered cathode (Al) compared to dry conditions. The separator displayed an anisotropy with tensile strengths differing by a factor of three between the longitudinal and transversal orientations. For investigating the failure of a whole pouch-cell, interrupted flat-punch and hemispherical-punch indentation tests were performed. Post-mortem CT analysis revealed that crack development is rather gradual than abrupt. The initiation and propagation of the failing cell structure were examined and related to the characteristics of the individual cell components. It could be concluded that for a physical based modeling of the deformation and fracture processes within the cell, understanding the mechanical behavior on component and on cell level is crucial.
锂离子电池中各个部件的本构力学行为对碰撞相关负载情况下内部电短路的发展具有根本性的影响。这些短路可能导致爆炸,热不稳定状态(所谓的热失控)。因此,单个部件和整个电池的机械性能的实验表征是电池系统安全相关评估的核心方面。本文介绍并比较了不同载荷模式下单个细胞组件和整个袋状细胞的力学特性的实验结果。特别研究了活性材料NMC和石墨在干湿条件下的不同力学行为。在压缩测试中,与干燥条件相比,电解质的存在使石墨层状阳极(Cu)的应力水平降低了约100%,使NMC层状阴极(Al)的应力水平降低了约20%。分离器显示出各向异性,其拉伸强度在纵向和横向之间相差三倍。为了研究整个袋胞的失效,进行了间断平冲和半冲压痕试验。尸检CT分析显示,裂纹的发展是渐进的,而不是突然的。研究了失败细胞结构的发生和繁殖,并将其与单个细胞成分的特性联系起来。可以得出结论,对于基于细胞内变形和断裂过程的物理建模,了解组件和细胞层面的力学行为至关重要。

In this article, different thermal treatment procedures were carefully investigated by electrochemical methods to find the optimized time and temperature for enhancing the electrochemical performance and activity of the graphite felt electrodes within the vanadium redox flow battery. Two prestigious and commercially used graphite felts of SGL GFD 4.65 EA and AvCarb G150 were used for this purpose. Cyclic voltammetry results initially were used to recognize the procedures with the most improved kinetics. This demonstrated the influences of treatment procedures on electrode kinetics by showing an improved electrode rate constant. In the following, area-specific resistance obtained by the polarization curves technique was used to examine the role of the thermal treatment procedure on improvement of the mass-transfer effect and, consequently, explore a treatment procedure to maximize the electrode activity. Both obtained CV and ASR data showed a better performance for thermally treated SGL 4.65 EA compared to that of AvCarb G150. Enhancing the electrode kinetics due to thermal treatment showed the largest contribution to reducing the ASR indicated by electrochemical impedance spectroscopy of the SGL 4.65 EA. The best electrode performance and activity was observed using the thermal treatment of the SGL 4.65 EA at 500/550 °C for 3/3.5 h with an ASR of 0.63/0.64 Ωcm2, respectively, lower than prior works with almost the same membrane properties. An interesting conclusion is that thermal treatment with an optimized procedure can sufficiently catalyze vanadium redox reactions on graphite felts better than those treated with electro-catalysts impressing no need for further electrode modification.
本文采用电化学方法对不同的热处理工艺进行了仔细的研究,以找到提高钒氧化还原液流电池内石墨毡电极电化学性能和活性的最佳时间和温度。为此使用了两种著名的商用石墨毡:SGL GFD 4.65 EA和AvCarb G150。循环伏安法的结果最初被用来识别动力学改善最大的过程。这证明了处理程序对电极动力学的影响,通过显示一个改进的电极速率常数。下面,利用极化曲线技术获得的面积比电阻来检验热处理工艺对改善传质效果的作用,从而探索一种使电极活性最大化的处理工艺。获得的CV和ASR数据均显示,与AvCarb G150相比,经过热处理的SGL 4.65 EA具有更好的性能。电化学阻抗谱显示,热处理对电极动力学的增强对降低ASR的贡献最大。在500/550℃条件下,对SGL 4.65 EA进行3/3.5 h的热处理,ASR为0.63/0.64 Ωcm2,其电极性能和活性最好,低于几乎相同膜性能的先前工作。一个有趣的结论是,与电催化剂处理相比,优化后的热处理工艺可以充分催化石墨毡上的钒氧化还原反应,无需进一步的电极修饰。

Battery-supercapacitor hybrid devices bridge the gap between batteries and supercapacitors, offering high energy and power densities with excellent cycling stability. However, integrating their distinct energy storage mechanisms remains challenging. A strategy to address this challenge is advanced interphase engineering at the electrode|solid electrolyte junction. In this work, we present an optimized solid electrolyte (anolyte) for a layered graphite anode, designed to enhance lithium intercalation, mitigate lithium plating, and promote the formation of a stable Solid-Electrolyte Interphase (SEI) for a Lithium-Ion Capacitor (LiC). This approach significantly improves capacity retention and long-term stability, reaching 100 % over 3000 cycles and maintaining 96.6 % of the maximum capacity at 10,000 cycles, while also maintaining the anode potential below the operating voltage of lithiated graphite (<0.25 V vs Li|Li+). These findings demonstrate a step toward high-performance hybrid capacitors with improved durability and energy storage capabilities.

Development of metal-supported solid oxide fuel cells with a thin-film electrolyte under an oxidizing atmosphere 氧化气氛下薄膜电解质金属支撑固体氧化物燃料电池的研制

Metal-supported solid oxide fuel cells (SOFCs), which have received much attention based on their high thermo-mechanical strength, are generally fabricated under a reducing atmosphere to prevent oxidation of the metal. The fabrication of metal-supported SOFCs under an oxidizing atmosphere resolves certain inherent issues related to fabrication in a reducing atmosphere, such as instability of the cathode materials and the inter-diffusion phenomenon. On the other hand, this approach limits the process temperature to prevent the excessive oxidation of the metal. In this work, a means by which to fabricate metal-supported SOFCs under an air environment is developed with a thin-film electrolyte, with deposition at room temperature. By introducing a pore-reducing layer while also controlling the viscosity of the coating solution, the surface of the anode is designed to be dense and flat, enabling the stable deposition of a dense thin-film electrolyte.

金属支撑固体氧化物燃料电池(sofc)因其高热机械强度而受到广泛关注,通常在还原性气氛下制造,以防止金属氧化。氧化气氛下金属负载sofc的制备解决了在还原气氛下制备的一些固有问题,如正极材料的不稳定性和相互扩散现象。另一方面,这种方法限制了工艺温度,以防止金属的过度氧化。在这项工作中,开发了一种在空气环境下用薄膜电解质制备金属支撑sofc的方法,并在室温下沉积。通过引入孔隙还原层,同时控制涂层溶液的粘度,阳极表面设计得致密而平坦,使致密薄膜电解质能够稳定沉积。考虑到有限的工艺温度,必须保持在1000°C以下,表现出显著的电化学性能。通过包括温度循环和事后分析在内的耐久性测试,观察到金属支撑的sofc具有显著的鲁棒性。

In this study, we developed gel polymer electrolytes (GPEs) containing cyclic carbonate side chains produced via UV-induced free radical polymerization, a fast and cost-efficient synthesis route, for Li-organic batteries. Cyclic carbonate methacrylate (CCMA) was copolymerized with diethylene glycol methyl ether methacrylate (DEGMEM) for 1 h. Then the resultant polymer films were swelled in 1 M LiPF6 in EC/DMC (50/50, v/v) with an electrolyte uptake of 500 %. These novel GPEs with an ionic conductivity of 1.1 mS cm−1 at 20 °C were electrochemically tested in Li//PTMA cells in comparison with LP30. They were found to show maximum discharge capacities (62.6 vs. 63.9 mAh g−1, GPE vs. LP30) at 0.1 C in addition to better compatibility with Li anodes (25.7 vs. 40.2 mV overpotential in Li stripping/plating tests) and a comparable electrochemical stability window. The results confirm that these GPEs are promising candidates for Li-organic batteries.
在这项研究中,我们开发了含有环状碳酸盐岩侧链的凝胶聚合物电解质(gpe),通过紫外线诱导自由基聚合制备,这是一种快速且经济的合成方法,用于有机锂电池。将环碳酸酯甲基丙烯酸酯(CCMA)与二甘醇甲基丙烯酸甲醚(DEGMEM)共聚1 h,然后在EC/DMC (50/50, v/v)的1 M LiPF6中膨胀,电解质吸收量为500%。这些新型gpe在20°C时离子电导率为1.1 mS cm−1,并在Li//PTMA电池中与LP30进行了电化学测试。在0.1 C下,它们显示出最大的放电容量(62.6 vs. 63.9 mAh g - 1, GPE vs. LP30),此外与锂阳极的相容性更好(锂剥离/镀测试中过电位25.7 vs. 40.2 mV),并且具有类似的电化学稳定性窗口。结果证实,这些gpe是锂有机电池的有希望的候选者。

Voltage reconstruction is a common technique used in estimation of degradation modes for aged Li-ion batteries. For real-life implementation, it is desirable for voltage reconstruction to work for partial charging as real-life batteries are rarely charged fully. In this pursuit, the presented work investigates a common practice of using truncated data from full charge as a representation of partial charging in voltage reconstruction. Usage of truncated data is prevalent despite known deviations between data collected from partial and full charge cycles and has resulted in a misconception that accurate voltage reconstruction is achievable using partial charging data. Therefore, voltage reconstruction errors between models parametrised using truncated data and actual partial charging data were compared. Results show a four-fold increase in error when using truncated data, which indicates that truncated data is an inappropriate proxy of partial charge. The findings also imply that partial charging is a limitation of voltage reconstruction modelling not highlighted before due to usage of truncated data. This limitation must be addressed to improve the applicability of voltage reconstruction. The study also emphasises the need to generate new battery degradation datasets with appropriate inclusion of partial charging data to enable the development of accurate and holistic models.
电压重构是估计老化锂离子电池退化模式的常用技术。在现实生活中,由于现实生活中的电池很少充满电,因此希望电压重构能够在部分充电时工作。在这一追求中,提出的工作调查了在电压重建中使用完全充电截断数据作为部分充电表示的常见做法。尽管从部分充电周期和完全充电周期收集的数据之间存在已知偏差,但截短数据的使用仍然很普遍,这导致了一种误解,即使用部分充电数据可以实现精确的电压重建。因此,比较了截断数据参数化模型与实际部分充电数据的电压重构误差。结果表明,截断后的数据误差增加了4倍,这表明截断后的数据不适合作为部分电荷的代表。研究结果还表明,部分充电是电压重建模型的限制,由于使用截断的数据,之前没有强调。为了提高电压重构的适用性,必须解决这一限制。该研究还强调需要生成新的电池退化数据集,其中适当包括部分充电数据,以便开发准确和全面的模型。

The Lithium-Ion Battery is attributed an enabling role for achieving climate policy goals by accelerating the shift of the mobility sector to renewable energy usage and improving renewable energy integration into the energy infrastructure through stationary storage. Thus, challenges related to further optimization of battery technology and its production that need to be tackled to achieve the set goals are manifold. Effective research funding planning is needed to efficiently use resources for advancing cell technologies and its production. However, despite being essential for identifying and prioritizing innovation needs based on technological performance, we perceive that an overview on how current issues in battery cell production hold for impact on a holistic operation site perspective is lacking. Thus, we aim at developing comprehensive process overview specifications for state-of-the-art lithium-ion battery cell production by applying a systematic, methodical approach as well as to derive critical problems and opportunities for targeted innovations application. We contribute to scientific literature by linking process streams and operational innovations in battery cell manufacturing to production management literature. Our findings furthermore have implications for both public research and industrial managers providing guidance on prioritizing development projects aiming at process management efficiency in battery cell manufacturing.
锂离子电池通过加速移动部门向可再生能源使用的转变,并通过固定存储改善可再生能源与能源基础设施的整合,在实现气候政策目标方面发挥了推动作用。因此,进一步优化电池技术及其生产需要解决的挑战是多方面的,以实现既定目标。有效的研究经费规划需要有效地利用资源来推进细胞技术及其生产。然而,尽管在技术性能的基础上识别和优先考虑创新需求是必不可少的,但我们认为,缺乏对电池生产中当前问题对整体运营现场影响的概述。因此,我们的目标是通过应用系统、有条不紊的方法,为最先进的锂离子电池生产开发全面的工艺概述规范,并为有针对性的创新应用得出关键问题和机会。我们通过将电池制造的工艺流程和操作创新与生产管理文献联系起来,为科学文献做出贡献。此外,我们的研究结果对公共研究和工业管理者都有启示,为电池制造过程管理效率的优先开发项目提供指导。
