Optimization of Si-PVDF Slurry Mixing and Electrode Fabrication Data for Enhanced Lithium-Ion Battery Performance

In this study, we present data related to optimizing Si-PVdF slurry mixing and electrode fabrication techniques to enhance the performance of lithium-ion batteries. Three critical experimental conditions are documented in Tables 1, 2, and 3, corresponding to different stages of the research. Table 1 records data from an initial unsuccessful attempt, while Table 2 captures data from a subsequent trial that did not yield successful results. Figure 1(a) clearly depicts an unsuccessful endeavor in the slurry mixing process of Si-PVdF, utilizing a volume of 0.9 ml of NMP. The image presented exhibits notable visual characteristics that illustrate the difficulties encountered in attaining a uniform slurry, as evidenced by noticeable irregularities and accumulation within the mixture [3]. The proposed visual representation emphasizes the crucial significance of accurate quantity control of NMP (N-Methyl-2-pyrrolidone) and sheds light on the challenges encountered during the electrode fabrication process in this research phase [4]. Fig. 1(b) depicts an additional instance of an unsuccessful endeavor in the slurry mixing process of Si-PVdF, wherein 1.0 ml of NMP was employed. The sharp and detailed image captures the persistence of issues observed in Fig. 1(a), emphasizing the importance of optimizing the NMP concentration. This striking visual evidence accentuates the necessity for fine-tuning the formulation to overcome challenges and attain a consistent slurry mixture. Table 3, on the other hand, represents the outcome of a successful experiment. Each table provides information on the materials used, including Silicon (Si), Polyvinylidene fluoride (PVdF), Graphite (G), and N-methyl-2-pyrrolidone (NMP), along with their respective weights and proportions. Figure 1(c) represents a significant achievement in the research, illustrating the successful fabrication of Si-PVdF slurry following a crucial aging procedure [5]. The visual representation conveys a perception of achievement through its consistent and seamless surface quality, effectively demonstrating enhanced bonding between the slurry material and the copper foil. Additionally, the tables include electrode and copper foil weight measurements and active Si weight percentage values. The data in these tables highlight the critical role of NMP quantity and aging time in achieving a homogenous slurry and successful electrode fabrication. Notably, the successful experiment in Table 3 is marked by improved adhesion of the slurry material to the copper foil, preventing delamination. This dataset provides valuable insights into the optimization process for Si-PVdF electrode fabrication in lithium-ion batteries. It can serve as a reference for future research in battery materials science [9].本研究公开了与优化硅-聚偏氟乙烯（Si-PVdF）浆料混合及电极制备工艺以提升锂离子电池性能相关的实验数据集。本研究共记录了三组关键实验条件，分别收录于表1、表2与表3，对应研究的不同阶段。其中表1记录了首次失败尝试的相关数据，表2收录了后续一次未获成功的试验数据。图1(a)清晰展示了使用0.9 mL N-甲基-2-吡咯烷酮（N-Methyl-2-pyrrolidone，下称NMP）进行Si-PVdF浆料混合的失败案例，该图像呈现出显著的视觉特征，直观体现了实现均匀浆料的难点：混合物中存在明显的不均匀性与团聚现象[3]。该可视化结果凸显了精准控制NMP用量的关键意义，并揭示了本研究阶段电极制备过程中面临的挑战[4]。图1(b)展示了另一次Si-PVdF浆料混合的失败尝试，此次使用了1.0 mL NMP。这张清晰锐利的图像捕捉到了图1(a)中出现的问题依然存在，进一步强调了优化NMP浓度的重要性。这一直观的视觉证据凸显了对配方进行微调以克服难题、获得均匀浆料混合物的必要性。表3则代表了成功实验的结果。各表格均提供了所用材料的相关信息，包括硅（Si）、聚偏氟乙烯（PVdF）、石墨（G）以及NMP，及其各自的质量与配比。图1(c)是本研究的一项重要突破，展示了经过关键老化工艺后成功制备的Si-PVdF浆料[5]。该可视化图像凭借均匀流畅的表面质感传递出成功的信号，直观证明了浆料与铜箔之间的粘结性能得到显著提升。此外，各表格还包含了电极与铜箔的质量测量数据以及活性硅的质量百分比数值。这些表格中的数据凸显了NMP用量与老化时间对获得均匀浆料和成功制备电极的关键作用。值得注意的是，表3中的成功实验实现了浆料与铜箔之间更优异的粘结性能，有效防止了分层现象。本数据集为锂离子电池Si-PVdF电极制备的优化流程提供了宝贵的参考见解，可作为未来电池材料科学领域研究的参照依据[9]。
