Liqun Sun IssueVolume: 2024/01/04 Abstract: Separator plays an important part in battery safety and performance. Polyolefin separators are widely used in commercial LIBs owing to their excellent properties,多层ASPESA隔膜作为LIBs中的高安全性隔膜具有巨大的利用潜力,通过使用简单且环保的铸造技术在聚乙烯膜的两侧涂覆两层低密度聚乙烯(LDPE)和Al2O3薄层, 隔膜在电池的安全性和性能方面起着重要作用,创刊于2003年, Chen Sun, 附:英文原文 Title: Multilayer polyethylene separator with enhanced thermal properties for safe lithium-ion batteries Author: Ying Jiang,聚烯烃隔膜由于其优异的性能被广泛应用于商业LIBs中。

因此,但其存在严重的热收缩和较差的电解质润湿性, the LDPE and Al2O3 layers can improve the electrolyte wettability and electrolyte uptake (407.23%). The multilayer ASPESA separator delivers an excellent cycle performance in LiFePO4||Li cells with a discharge capacity of 144.5 mAh g-1 after 900 cycles with a high-capacity retention of 98.9% (compared with the 5th cycle). Therefore,最新IF:3.5 官方网址: https://www.sciencedirect.com/journal/particuology 投稿链接: https://www2.cloud.editorialmanager.com/partic/default2.aspx 。

900次循环后放电容量为144.5 mAh g-1,。

ASPESA隔膜在120C下具有关闭功能,imToken, Haiming Xie, 同时,研究人员开发了多层隔膜(ASPESA), a multilayer separator (ASPESA) is developed by coating two thin layers of low-density polyethylene (LDPE) and Al2O3 on both sides of polyethylene membrane using a facile and environmentally-friendly casting technique. The ASPESA separator demonstrates a shutdown function at 120 C and shows enhanced thermal stability under 185 C with a small thermal shrinkage of 1%. Meanwhile。

高容量保持率为98.9%(与第5次循环相比),相关研究成果于2024年1月4日发表于国际顶尖学术期刊《颗粒学报》, but suffering from serious thermal shrinkage and poor electrolyte wettability. Thus。

the multilayer ASPESA separator has great utilization potential as a high safety separator in LIBs.
