A new type of aqueous aluminide ceramic coating polyethylene (ACP) separators is prepared by a simple spreader coating process using aluminum oxide (Al2O3) and boehmite (AlOOH) as the ceramic coating particles. During the preparation of the separator, water is used as the solvent and BYK (Beck Chemical Co., Ltd.) additives are used as the aqueous assistant. The as-prepared ACP separators present more outstanding synthetic properties than commercial polyethylene (PE) separators. In addition, compared with Al2O3-coated PE (PE-Al2O3) separators, AlOOH-coated PE (PE-AlOOH) separators have superior synthetic properties, including a better interface stability and a higher liquid electrolyte uptake due to the presence of hydroxyl groups (-OH). As a consequence, the LiNi0.3Co0.3Mn0.3O| Li metal half-cells with PE-AlOOH separators have a good cycling stability and a high rate performance. The advantages of the PE-AlOOH separators make them promising candidates for applications in high power lithium-ion batteries.

锂离子电池用铝化铝陶瓷水涂层隔板

通过简单的铺展涂覆工艺,使用氧化铝(Al 2 O 3)和勃姆石(AlOOH)作为陶瓷涂层颗粒,制备了新型的铝化铝陶瓷涂层聚乙烯(ACP)隔板。在制备分离器的过程中,使用水作为溶剂,并使用BYK(贝克化学有限公司)添加剂作为水性助剂。所制备的ACP隔膜比商用聚乙烯(PE)隔膜具有更出色的合成性能。此外,与涂有Al 2 O 3的PE(PE-Al 2 O 3)隔膜,AlOOH涂层的PE(PE-AlOOH)隔膜具有优异的合成性能,包括由于存在羟基(-OH)而具有更好的界面稳定性和更高的液体电解质吸收能力。结果,LiNi 0.3 Co 0.3 Mn 0.3 O |。带有PE-AlOOH隔膜的锂金属半电池具有良好的循环稳定性和高倍率性能。PE-AlOOH隔膜的优点使其成为大功率锂离子电池应用的有希望的候选者。
