摘要:
A selected electrolyte composition comprising aluminum and a lower molecular weight fluorinated organic anion which can be an ionic liquid. The fluorinated organic anion can be bis(trifluorosulfonyl)imide. The composition can be used in electroplating or batteries. A preferred example is use of Al(NTf 2 ) 3 with one or more other moieties. A moisture insensitive electroplating method comprising: providing at least one aluminum electroplating system comprising at least one electroplating composition which is adapted for electroplating aluminum onto a substrate; electroplating aluminum onto the substrate from the at least one electroplating composition comprising: (i) aluminum cation, and (ii) at least one anion which is a fluorinated organic anion having molecular weight of 750 g/mol or less. Optionally, the aluminum cation is in, or is not in, aluminate form. Use of highly reactive aluminum compounds such as aluminum halides can be avoided.
摘要(中):
一种选择的电解质组合物,其包含可以是离子液体的铝和较低分子量的氟化有机阴离子。 氟化有机阴离子可以是双(三氟磺酰基)酰亚胺。 该组合物可用于电镀或电池。 优选的实例是使用Al(NTf2)3与一个或多个其它部分。 一种不透湿电镀方法,包括:提供至少一种铝电镀系统,其包括至少一种适用于将铝电镀到基底上的电镀组合物; 从所述至少一种电镀组合物将铝电镀到所述基材上,所述电镀组合物包含:(i)铝阳离子,和(ii)至少一种阴离子,其是分子量为750g / mol或更低的氟化有机阴离子。 任选地,铝阳离子是或不是铝酸盐形式。 可以避免使用高活性铝化合物如卤化铝。
