  摘要：

  离子液体对于金属的电沉积具有重要意义，由于其负的标准电位，无法从水溶液电解质中沉积。本文中，通过1-乙基-3-甲基咪唑氯离子液体中的电沉积方法，在非织造聚合物上涂覆铝，并随后用于锂离子电池的三维集流体。我们研究了在面向工艺的条件下，离子液体（IL）用于铝电沉积的长期稳定性。通过顶空气相色谱-质谱法、热裂解-气相色谱-质谱法（Py-GC/MS）和1H/13C核磁共振谱（NMR）对降解产物进行了分析。主要分解产物源自热降解，特别是烷基链的断裂，被鉴定为氯甲烷、二氯甲烷、甲基咪唑、乙基咪唑和去质子的1-乙基-3-甲基咪唑。

  The solution of [RhCl(PPh3)(3)] in acidic 1-ethyl-3-methylimidazolium chloroaluminate(III) ionic liquid (AlCl3 molar fraction. x(AlCl3) 0.67) was investigated by H-1 and P-31H-1} NMR. One triphenyl phosphine is lost from the complex and is protonated in the acidic media, and cis-[Rh(PPh3)(2)ClX], (2), where X is probably [AlCl4](-), is formed. On, standing, 2 is converted to trans-[Rh(H)(PPh3)(2)X]. (3). The reaction of 2 and H-2 also produces trans-[Rh(H)(PPh3)(2)X], (3) H-1 and P-31H-1} NMR support the suggestion that a weak ligand such as [AlCl4](-) present in solution may interact with the metal centre. When [RhCl(PPh3)(3)] is dissolved in CH2Cl2/AlCl3/HCl for comparison, two exchanging isomers of what is probably [RhH(mu-Cl)(2)AlCl2}(mu-Cl)AlCl3}(PPh3)(2)]. (6) and (7), are formed.

  Ionic liquids are of great importance for electrodeposition of metals, which can't be deposited from aqueous electrolytes due to their negative standard potentials. In this paper non-woven polymers were coated with aluminium by electrodeposition from 1-ethyl-3-methyl-imidazolium chloride and subsequently established as 3D current collectors for lithium-ion batteries. We investigated the long-term stability of the ionic liquid (IL) for electrodeposition of aluminium under process-oriented conditions. The degradation products were analysed by headspace gas chromatography-mass spectrometry, pyrolysis-gas chromatography-mass spectrometry (Py-GC/MS) and 1H/13C nuclear magnetic resonance spectroscopy (NMR). The main decomposition products derived from thermal degradation, especially from cleavage of an alkyl chain and were identified as chloromethane, dichloromethane, methylimidazole, ethylimidazole and deprotonated 1-ethyl-3-methylimidazole.
