The present invention relates to polymers used as rolling lubricating agents, to compositions comprising said polymers, and to alkali metal films including the polymers or compositions on the surface(s) thereof. The use of said polymers and compositions is also described for strip-rolling alkali metals or alloys thereof in order to obtain thin films. Methods for producing said thin films, which are suitable for use in electrochemical cells, are also described. The present invention proposes an improved lubricant according to formula I, which, for example, achieves enhanced conductivity, and/or enables the production of electrochemical cells having an improved life span in cycles. 本发明涉及用作轧制润滑剂的聚合物，涉及包含所述聚合物的组合物，以及涉及在其表面上包含该聚合物或组合物的碱金属膜。还描述了所述聚合物和组合物用于轧制带的碱金属或其合金以获得薄膜的用途。本发明还公开了用于制备所述薄膜的方法，所述薄膜适用于电化学电池。本发明提出根据通式I的改进的润滑剂，其例如获得改进的导电性，和/或使得能够制备具有改进的循环寿命范围的电化学电池。
