Abstract: A relithiated Li intercalation material for producing Li metal or an alloy thereof or for pre-lithiating an electrode material as well as an anode and an electrolysis cell comprising same are provided. A method of producing Li metal or an alloy thereof or for pre-lithiating an electrode material is also provided. This method comprises carrying out a Li production electrolysis reaction in the electrolysis cell, wherein the electrolysis cell comprises the relithiated Li intercalation material as an anode, a current collector as a cathode, and an electrolyte comprising a lithium salt.

Abstract: Polymers used as rolling lubricating agents, to compositions including 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. 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.
