发明名称 Sustainable Current Collectors for Lithium Batteries
摘要 The claimed invention relates to a current collector product for one or more galvanic battery cells. Currently, the metal considered as current collector for the negative electrode is copper. Some of the disadvantages of copper are that it is a rare, heavy and expensive element. To alleviate at least some of the problems of the prior art battery cells, at least part of the current collector electrode supporting portion is composed of pure iron or an iron alloy with less than 10 percent by weight of impurities or alloying constituents. The claimed invention also relates to a galvanic, lithium or sodium, battery cell and to a method for producing a current collector product.

主权项 1. A current collector product for one or more galvanic battery cells, wherein the current collector product is adapted to be incorporated into one or more lithium or sodium battery cell(s) and comprises at least one supporting portion adapted for supporting an electrode material thereon to allow transfer of electrons between the current collector product and the electrode material, characterized in that at least a part of the supporting portion is composed of pure iron or an iron alloy with less than 10 percent by weight of impurities or alloying constituents.
