Abstract
In this study, we explored the potential of illite sourced from Yeongdong-eup, South Korea, as a filler in polymer electrolytes for all-solid-state Li-ion batteries. The illite was expanded (EI) by acid treatment and UV curing was employed to synthesize the polymer electrolytes. The Li+ ionic conductivity of the polymer electrolytes was measured at various EI contents, revealing the highest conductivity of 1.08 × 10−2 S cm−1 at 4 wt% of the EI. The electrochemical performance of NMC cells assembled with the EI-incorporated polymer electrolyte showed a good discharge capacity of over 158.6 mAh g−1 with a coulombic efficiency of 99%. These findings demonstrate the significant potential of EI as a sustainable and efficient filler material for enhancing the performance of polymer-based all-solid-state Li batteries. This study highlighted the applicability of illite sourced from South Korea and its potential contribution to the development of polymer-based all-solid-state batteries.
在这项研究中,我们探讨了韩国永同邑的伊利石作为全固态锂离子电池聚合物电解质填料的潜力。伊利石经酸处理膨胀(EI)后,采用紫外固化法合成聚合物电解质。测量了不同 EI 含量下聚合物电解质的 Li+ 离子电导率,结果表明,在 EI 含量为 4 wt% 时,电导率最高,为 1.08 × 10-2 S cm-1。使用加入了 EI 的聚合物电解质组装的 NMC 电池的电化学性能良好,放电容量超过 158.6 mAh g-1,库仑效率达到 99%。这些研究结果表明,EI 作为一种可持续的高效填充材料,在提高聚合物全固态锂电池性能方面具有巨大潜力。这项研究强调了来自韩国的伊利石的适用性及其对聚合物全固态电池开发的潜在贡献。

期刊介绍:
Coatings is an international, peer-reviewed open access journal of coatings and surface engineering. It publishes reviews, research articles, communications and technical notes. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. There is no restriction on the length of the papers. Full experimental and/or methodical details must be provided. There are, in addition, unique features of this journal:
* manuscripts regarding research proposals and research ideas will be particularly welcomed
* electronic files or software regarding the full details of the calculation and experimental procedure - if unable to be published in a normal way - can be deposited as supplementary material
